Abstract
INTRODUCTION Apolipoprotein E E4 allele (APOE E4) and slow gait are independently associated with cognitive impairment and dementia. However, it is unknown whether their coexistence is associated with poorer cognitive performance and its underlying mechanism in neurodegenerative diseases. METHODS Gait speed, APOE E4, cognition, and neuroimaging were assessed in 480 older adults with neurodegeneration. Participants were grouped by APOE E4 presence and slow gait. Mediation analyses were conducted to determine if brain structures could explain the link between these factors and cognitive performance. RESULTS APOE E4 carriers with slow gait had the lowest global cognitive performance and smaller gray matter volumes compared to non-APOE E4 carriers with normal gait. Coexistence of APOE E4 and slow gait best predicted global and domain-specific poorer cognitive performances, mediated by smaller gray matter volume. DISCUSSION Gait slowness in APOE E4 carriers with neurodegenerative diseases may indicate extensive gray matter changes associated with poor cognition. HIGHLIGHTS APOE E4 and slow gait are risk factors for cognitive decline in neurodegenerative diseases. Slow gait and smaller gray matter volumes are associated, independently of APOE E4. Worse cognition in APOE E4 carriers with slow gait is explained by smaller GM volume. Gait slowness in APOE E4 carriers indicates poorer cognition-related brain changes.

Abstract
Apolipoprotein E (apoE), a polymorphic plasma protein, plays a pivotal role in lipid transportation. The human apoE gene possesses three major alleles (ε2, ε3, and ε4), which differ by single amino acid (cysteine to arginine) substitutions. The ε4 allele represents the primary genetic risk factor for Alzheimer's disease (AD), whereas the ε2 allele protects against the disease. Knowledge of a patient's apoE genotype has high diagnostic value. A recent study has introduced an LC-MRM-MS-based proteomic approach for apoE isoform genotyping using stable isotope-labeled peptide internal standards (SIS). Here, our goal was to develop a simplified LC-MRM-MS assay for identifying apoE genotypes in plasma samples, eliminating the need for the use of SIS peptides. To determine the apoE genotypes, we monitored the chromatographic peak area ratios of isoform-specific peptides relative to a peptide that is common to all apoE isoforms. The assay results correlated well with the standard TaqMan allelic discrimination assay, and we observed a concordance between the two methods for all but three out of 172 samples. DNA sequencing of these three samples has confirmed that the results of the LC-MRM-MS method were correct. Thus, our simplified UPLC-MRM-MS assay is a feasible and reliable method for identifying apoE genotypes without using SIS internal standard peptides. The approach can be seamlessly incorporated into existing quantitative proteomics assays and kits, providing additional valuable apoE genotype information. The principle of using signal ratios of the protein isoform-specific peptides to the peptide common for all of the protein isoforms has the potential to be used for protein isoform determination in general.

Abstract
Vitamin D (VitD) deficiency can exacerbate AD progression and may cause changes in brain metabolite levels that can be detected by magnetic resonance spectroscopy (MRS). The purpose of this study was to determine whether chronic VitD deficiency in an AD mouse model caused persistent metabolite levels changes in the hippocampus associated with memory performance. Six-month-old APPSwe/PS1ΔE9 (APP/PS1) mice (N = 14 mice/group) were fed either a VitD deficient (VitD-) diet or a control diet. Metabolite level changes in the hippocampus were evaluated by 1H MRS using a 9.4 T MRI. Ventricle volume was assessed by imaging and spatial memory was evaluated using the Barnes maze. All measurements were made at 6, 9, 12, and 15 months of age. At 15 months of age, amyloid plaque load and astrocyte number were evaluated histologically (N = 4 mice/group). Levels of N-acetyl aspartate and creatine were lower in VitD- mice compared to control diet mice at 12 months of age. VitD deficiency did not change ventricle volume. Lactate levels increased over time in VitD- mice and increases from 12 to 15 months were negatively correlated with changes in primary latency to the target hole in the Barns Maze. VitD- mice showed improved spatial memory performance compared to control diet mice. VitD- mice also had more astrocytes in the cortex and hippocampus at 15 months than control diet mice. This study suggests that severe VitD deficiency in APP/PS1 mice may lead to compensatory changes in metabolite and astrocyte levels that contribute to improved performance on spatial memory tasks.

Abstract
BACKGROUND Within the spectrum of Lewy body disorders (LBD), both Parkinson's disease (PD) and dementia with Lewy bodies (DLB) are characterized by gait and balance disturbances, which become more prominent under dual-task (DT) conditions. The brain substrates underlying DT gait variations, however, remain poorly understood in LBD. OBJECTIVE To investigate the relationship between gray matter volume loss and DT gait variations in LBD. METHODS Seventy-nine participants including cognitively unimpaired PD, PD with mild cognitive impairment, PD with dementia (PDD), or DLB and 20 cognitively unimpaired controls were examined across a multi-site study. PDD and DLB were grouped together for analyses. Differences in gait speed between single and DT conditions were quantified by dual task cost (DTC). Cortical, subcortical, ventricle, and cerebellum brain volumes were obtained using FreeSurfer. Linear regression models were used to examine the relationship between gray matter volumes and DTC. RESULTS Smaller amygdala and total cortical volumes, and larger ventricle volumes were associated with a higher DTC across LBD and cognitively unimpaired controls. No statistically significant interaction between group and brain volumes were found. Adding cognitive and motor covariates or white matter hyperintensity volumes separately to the models did not affect brain volume and DTC associations. CONCLUSION Gray matter volume loss is associated with worse DT gait performance compared to single task gait, across cognitively unimpaired controls through and the LBD spectrum. Impairment in DT gait performance may be driven by age-related cortical neurodegeneration.

Abstract
INTRODUCTION Falls are common for people with lower-limb amputations (PLLA). Low balance confidence is also prevalent, is worse in PLLA not reporting walking automaticity, and is known to negatively affect prosthesis use, social engagement, and quality of life. Moreover, walking with a prosthesis requires continuous attention. Low balance confidence may act as a distractor imposing an additional cognitive load on the already cognitively demanding task of walking with a prosthesis. METHODS Adults with unilateral, transtibial amputations were recruited. The Activities-specific Balance Confidence (ABC) scale quantified balance confidence. The L Test assessed basic walking abilities under single-task (ST) (usual) and dual-task (DT) (walking while counting backwards) conditions. The relative change in gait and secondary task performance between conditions (ie, DT cost) was calculated. Separate multivariable linear regressions examined the association of balance confidence on the L Test. RESULTS Forty-four PLLA (56.6 ± 12.6 years) participated. An independent association of the ABC to ST ( P < 0.001, R 2 = 0.56) and DT ( P = 0.008, R 2 = 0.43) L Test performance was observed. A 1% ABC increase was related with a 0.24 (95% confidence interval, 0.35-0.14) and 0.23 (95% confidence interval, 0.39-0.06) second reduction with the ST and DT L Test, respectively. No association to DT cost was observed. CONCLUSIONS Balance confidence influences basic walking abilities yet does not modulate the added cognitive load associated with DT. Interventions that address balance confidence may be beneficial throughout rehabilitation. This research is novel and offers the possibility for alternative avenues for focus in rehabilitation and falls prevention in a population at high risk for falls.

Abstract
BACKGROUND Older adults presenting with dual-decline in cognition and walking speed face a 6-fold higher risk for dementia compared with those showing no decline. We hypothesized that the metabolomics profile of dual-decliners would be unique even before they show signs of decline in cognition and gait speed. OBJECTIVE The objective of this study was to determine if plasma metabolomics signatures can discriminate dual-decliners from no decliners, purely cognitive decliners, and purely motor decliners prior to decline. METHODS A retrospective cross-sectional study using baseline plasma for untargeted metabolomics analyses to investigate early signals of later dual-decline status in study participants (n = 76) with convenient sampling. Dual-decline was operationalized as decline in gait speed (>10 cm/s) and cognition (>2 points decline in Montreal Cognitive Assessment score) on at least two consecutive 6-monthly assessments. The participants' decliner status was evaluated 3 years after the blood sample was collected. Pair-wise comparison of detected compounds was completed using principal components and hierarchical clustering analyses. RESULTS Analyses did not detect any cluster separation in untargeted metabolomes across baseline groups. However, follow-up analyses of specific molecules detected 4 compounds (17-Hydroxy-12-(hydroxymethyl)-10-oxo-8 oxapentacyclomethyl hexopyranoside, Fleroxacin, Oleic acid, and 5xi-11,12-Dihydroxyabieta-8(14),9(11),12-trien-20-oic acid) were at significantly higher concentration among the dual-decliners compared to non-decliners. The pure cognitive decliner group had significantly lower concentration of six compounds (1,3-nonanediol acetate, 4-(2-carboxyethyl)-2-methoxyphenyl beta-D-glucopyranosiduronic acid, oleic acid, 2E-3-[4-(sulfo-oxy)phenyl] acrylic acid, palmitelaidic acid, and myristoleic acid) compared to the non-decliner group. CONCLUSIONS The unique metabolomics profile of dual-decliners warrants follow-up metabolomics analysis. Results may point to modifiable pathways.

Abstract
Falls prevention and management in older adults is a critical global challenge. One of the key risk factors for falls is the use of certain medications. Therefore, to prevent medication-related falls, the following is recommended in the recent World Guidelines for Falls Prevention and Management: (1) assess for fall history and the risk of falls before prescribing potential fall-risk-increasing drugs (FRIDs), (2) use a validated, structured screening and assessment tool to identify FRIDs when performing a medication review, (3) include medication review and appropriate deprescribing of FRIDs as a part of the multifactorial falls prevention intervention, and (4) in long-term care residents, if multifactorial intervention cannot be conducted due to limited resources, the falls prevention strategy should still always include deprescribing of FRIDs.In the present statement paper, the working group on medication-related falls of the World Guidelines for Falls Prevention and Management, in collaboration with the European Geriatric Medicine Society (EuGMS) Task and Finish group on FRIDs, outlines its position on how to implement and execute these recommendations in clinical practice.Preferably, the medication review should be conducted as part of a comprehensive geriatric assessment to produce a personalized and patient-centered assessment. Furthermore, the major pitfall of the published intervention studies so far is the suboptimal implementation of medication review and deprescribing. For the future, it is important to focus on gaining which elements determine successful implementation and apply the concepts of implementation science to decrease the gap between research and practice.

Abstract
Importance Exercise, cognitive training, and vitamin D may enhance cognition in older adults with mild cognitive impairment (MCI). Objective To determine whether aerobic-resistance exercises would improve cognition relative to an active control and if a multidomain intervention including exercises, computerized cognitive training, and vitamin D supplementation would show greater improvements than exercise alone. Design, Setting, and Participants This randomized clinical trial (the SYNERGIC Study) was a multisite, double-masked, fractional factorial trial that evaluated the effects of aerobic-resistance exercise, computerized cognitive training, and vitamin D on cognition. Eligible participants were between ages 65 and 84 years with MCI enrolled from September 19, 2016, to April 7, 2020. Data were analyzed from February 2021 to December 2022. Interventions Participants were randomized to 5 study arms and treated for 20 weeks: arm 1 (multidomain intervention with exercise, cognitive training, and vitamin D), arm 2 (exercise, cognitive training, and placebo vitamin D), arm 3 (exercise, sham cognitive training, and vitamin D), arm 4 (exercise, sham cognitive training, and placebo vitamin D), and arm 5 (control group with balance-toning exercise, sham cognitive training, and placebo vitamin D). The vitamin D regimen was a 10 000 IU dose 3 times weekly. Main Outcomes and Measures Primary outcomes were changes in ADAS-Cog-13 and Plus variant at 6 months. Results Among 175 randomized participants (mean [SD] age, 73.1 [6.6] years; 86 [49.1%] women), 144 (82%) completed the intervention and 133 (76%) completed the follow-up (month 12). At 6 months, all active arms (ie, arms 1 through 4) with aerobic-resistance exercise regardless of the addition of cognitive training or vitamin D, improved ADAS-Cog-13 when compared with control (mean difference, -1.79 points; 95% CI, -3.27 to -0.31 points; P = .02; d = 0.64). Compared with exercise alone (arms 3 and 4), exercise and cognitive training (arms 1 and 2) improved the ADAS-Cog-13 (mean difference, -1.45 points; 95% CI, -2.70 to -0.21 points; P = .02; d = 0.39). No significant improvement was found with vitamin D. Finally, the multidomain intervention (arm 1) improved the ADAS-Cog-13 score significantly compared with control (mean difference, -2.64 points; 95% CI, -4.42 to -0.80 points; P = .005; d = 0.71). Changes in ADAS-Cog-Plus were not significant. Conclusions and Relevance In this clinical trial, older adults with MCI receiving aerobic-resistance exercises with sequential computerized cognitive training significantly improved cognition, although some results were inconsistent. Vitamin D supplementation had no effect. Our findings suggest that this multidomain intervention may improve cognition and potentially delay dementia onset in MCI. Trial Registration ClinicalTrials.gov Identifier: NCT02808676.

Abstract
BACKGROUND/OBJECTIVE While several psychotropic and cardiovascular drugs have been identified as fall-risk-increasing drugs (FRIDs) in older adults, the intervening mechanisms linking FRIDs and falls are unclear. It is plausible that gait performance is an intermediate variable on the causal pathway between FRIDs and falls. The current evidence on the relationship between medication use and gait performance in older adults is scarce. We aimed to assess the association between FRIDs and gait performance in community-dwelling older adults. METHODS This was a cross-sectional analysis using data from the Gait and Brain Study, a study of community-dwelling older adults aged 65 years old and over (N = 345). The following drug classes were assessed: antidepressants, benzodiazepines, alpha-blockers, beta-blockers, vasodilators, diuretics, statins and aspirin. Medication use was ascertained through validated questionnaires and electronic medical records. Multiple linear regression models were used to assess the association between each of the drug classes and gait speed and gait variability. Gait variability was expressed as the coefficient of variation (CV = mean/standard deviation) of stride time. Models were adjusted for age, sex, education, body mass index (BMI), mini-mental status exam (MMSE) score, Geriatric Depression Scale (GDS) score, general activity level, use of other FRIDs and comorbidity propensity score. RESULTS Diuretic use was associated with significantly reduced gait speed (B = -7.97 cm/s, 95% CI: -13.94, -2.00, P = 0.009). Statin use was associated with significantly increased stride time CV (B = 0.13, 95% CI: 0.02, 0.24, P = 0.026). Other drugs did not have a statistically significant relationship with gait speed or variability. CONCLUSION The association between diuretic use and reduced gait speed is consistent with existing evidence on diuretic use and increased fall risk. The association between statins and increased stride time variability is notable given inconclusive evidence in previous studies. Our results provide initial estimates of the association between FRIDs and gait performance in older adults for future longitudinal studies.

Abstract
BACKGROUND Neuropsychiatric symptoms (NPS) are a core feature of most neurodegenerative and cerebrovascular diseases. White matter hyperintensities and brain atrophy have been implicated in NPS. We aimed to investigate the relative contribution of white matter hyperintensities and cortical thickness to NPS in participants across neurodegenerative and cerebrovascular diseases. METHODS Five hundred thirteen participants with one of these conditions, i.e. Alzheimer's Disease/Mild Cognitive Impairment, Amyotrophic Lateral Sclerosis, Frontotemporal Dementia, Parkinson's Disease, or Cerebrovascular Disease, were included in the study. NPS were assessed using the Neuropsychiatric Inventory - Questionnaire and grouped into hyperactivity, psychotic, affective, and apathy subsyndromes. White matter hyperintensities were quantified using a semi-automatic segmentation technique and FreeSurfer cortical thickness was used to measure regional grey matter loss. RESULTS Although NPS were frequent across the five disease groups, participants with frontotemporal dementia had the highest frequency of hyperactivity, apathy, and affective subsyndromes compared to other groups, whilst psychotic subsyndrome was high in both frontotemporal dementia and Parkinson's disease. Results from univariate and multivariate results showed that various predictors were associated with neuropsychiatric subsyndromes, especially cortical thickness in the inferior frontal, cingulate, and insula regions, sex(female), global cognition, and basal ganglia-thalamus white matter hyperintensities. CONCLUSIONS In participants with neurodegenerative and cerebrovascular diseases, our results suggest that smaller cortical thickness and white matter hyperintensity burden in several cortical-subcortical structures may contribute to the development of NPS. Further studies investigating the mechanisms that determine the progression of NPS in various neurodegenerative and cerebrovascular diseases are needed.

Abstract
BACKGROUND Acute change in gait speed while performing a mental task [dual-task gait cost (DTC)], and hyperintensity magnetic resonance imaging signals in white matter are both important disability predictors in older individuals with history of stroke (poststroke). It is still unclear, however, whether DTC is associated with overall hyperintensity volume from specific major brain regions in poststroke. METHODS This is a cohort study with a total of 123 older (69 ± 7 years of age) participants with history of stroke were included from the Ontario Neurodegenerative Disease Research Initiative. Participants were clinically assessed and had gait performance assessed under single- and dual-task conditions. Structural neuroimaging data were analyzed to measure both, white matter hyperintensity (WMH) and normal appearing volumes. Percentage of WMH volume in frontal, parietal, occipital, and temporal lobes as well as subcortical hyperintensities in basal ganglia + thalamus were the main outcomes. Multivariate models investigated associations between DTC and hyperintensity volumes, adjusted for age, sex, years of education, global cognition, vascular risk factors, APOE4 genotype, residual sensorimotor symptoms from previous stroke and brain volume. RESULTS There was a significant positive global linear association between DTC and hyperintensity burden (adjusted Wilks' λ = .87, P = .01). Amongst all WMH volumes, hyperintensity burden from basal ganglia + thalamus provided the most significant contribution to the global association (adjusted β = .008, η2 = .03; P = .04), independently of brain atrophy. CONCLUSIONS In poststroke, increased DTC may be an indicator of larger white matter damages, specifically in subcortical regions, which can potentially affect the overall cognitive processing and decrease gait automaticity by increasing the cortical control over patients' locomotion.

Abstract
BACKGROUND Falls and fall-related injuries are common in older adults, have negative effects on functional independence and quality of life and are associated with increased morbidity, mortality and health related costs. OBJECTIVE To synthesize evidence-based and expert consensus-based 2022 world guidelines for the management and prevention of falls in older adults. These recommendations consider a person-centred approach that includes the preferences of the patient, caregivers and other stakeholders, gaps in previous guidelines, recent developments in e-health and both local context and resources. RECOMMENDATIONS All older adults should be advised on falls prevention and physical activity. Opportunistic case finding for falls risk is recommended for communitydwelling older adults. An algorithm is proposed to stratify falls risk and interventions for persons at low, moderate or high risk. Those considered at high risk should be offered a comprehensive multifactorial falls risk assessment with a view to co-design and implement personalised multidomain interventions. Other recommendations cover details of assessment and intervention components and combinations, and recommendations for specific settings and populations. CONCLUSIONS The core set of recommendations provided will require flexible implementation strategies that consider both local context and resources.

Abstract
Changes in functional brain connectivity (FBC) may indicate how lifestyle modifications can prevent the progression to dementia; FBC identifies areas that are spatially separate but temporally synchronized in their activation and is altered in those with mild cognitive impairment (MCI), a prodromal state between healthy cognitive aging and dementia. Participants with MCI were randomly assigned to one of five study arms. Three times per week for 20-weeks, participants performed 30-min of (control) cognitive training, followed by 60-min of (control) physical exercise. Additionally, a vitamin D3 (10,000 IU/pill) or a placebo capsule was ingested three times per week for 20-weeks. Using the CONN toolbox, we measured FBC change (Post-Pre) across four statistical models that collapsed for and/or included some or all study arms. We conducted Pearson correlations between FBC change and changes in physical and cognitive functioning. Our sample included 120 participants (mean age: 73.89 ± 6.50). Compared to the pure control, physical exercise (model one; p-False Discovery Rate (FDR) < 0.01 & < 0.05) with cognitive training (model two; p-FDR = < 0.001), and all three interventions combined (model four; p-FDR = < 0.01) demonstrated an increase in FBC between regions of the Default-Mode Network (i.e., hippocampus and angular gyrus). After controlling for false discovery rate, there were no significant correlations between change in connectivity and change in cognitive or physical function. Physical exercise alone appears to be as efficacious as combined interventional strategies in altering FBC, but implications for behavioral outcomes remain unclear.

Abstract
INTRODUCTION Mild cognitive impairment (MCI) affects obstacle negotiation capabilities, potentially increasing the risk of falls in older adults. However, it is unclear whether smaller brain volumes typically observed in older individuals with MCI are related to the observed hazardous obstacle negotiation in this population. METHODS A total of 93 participants (71.9 ± 5.36 years of age; MCI = 53/control = 40) from the Gait and Brain Study were analyzed. Gray matter (GM) volumes from the frontal, temporal, and parietal lobes were entered in the analysis. Gait performance was recorded using a 6-m electronic walkway during two cognitive load conditions while approaching and stepping over an obstacle: (1) single-task and (2) while counting backwards by 1s from 100 (dual-task). Anticipatory adjustments in gait performance to cross an "ad hoc" obstacle were electronically measured during pre-crossing phases: early (3 steps before the late phase) and late (3 steps before obstacle). Association between the percentage of change in average gait speed and step length from early to late (i.e., anticipatory adjustments) and GM volumes was investigated using multivariate models adjusted for potential confounders. RESULTS Anticipatory adjustments in gait speed (Wilks' lambda: 0.35; Eta2: 0.64; p = 0.01) and step length (Wilks' lambda: 0.33; Eta2: 0.66; p = 0.01) during dual-task conditions were globally associated with GM volumes in MCI. Individuals with MCI with smaller GM volumes in the left inferior frontal gyrus, left hippocampus, right hippocampus, and right entorhinal cortex made significantly fewer anticipatory gait adjustments prior to crossing the obstacle. CONCLUSION Frontotemporal atrophy may affect obstacle negotiation capabilities potentially increasing the risk of falls in MCI.

Abstract
BackgroundParkinson’s disease (PD) and dementia with Lewy bodies (DLB) are part of a spectrum of Lewy body disorders, who exhibit a range of cognitive and gait impairments. Cognitive-motor interactions can be examined by performing a cognitive task while walking and quantified by a dual task cost (DTC). White matter hyperintensities (WMH) on magnetic resonance imaging have also been associated with both gait and cognition. Our goal was to examine the relationship between DTC and WMH in the Lewy body spectrum, hypothesizing DTC would be associated with increased WMH volume.MethodsSeventy-eight participants with PD, PD with mild cognitive impairment (PD-MCI), PD with dementia or DLB (PDD/DLB), and 20 cognitively unimpaired participants were examined in a multi-site study. Gait was measured on an electronic walkway during usual gait, counting backward, animal fluency, and subtracting sevens. WMH were quantified from magnetic resonance imaging using an automated pipeline and visual rating. A median split based on DTC was performed. Models included age as well as measures of global cognition and cardiovascular risk.ResultsCompared to cognitively unimpaired participants, usual gait speed was lower and DTC was higher in PD-MCI and PDD/DLB. Low DTC participants had higher usual gait speed. WMH burden was greater in high counting DTC participants. Frontal WMH burden remained significant after adjusting for age, cardiovascular risk and global cognition.ConclusionIncreased DTC was associated with higher frontal WMH burden in Lewy body disorders after adjusting for age, cardiovascular risk, and global cognition. Higher DTC was associated with age.

Abstract
BACKGROUND AND PURPOSE The pathophysiology of Parkinson's disease (PD) negatively affects brain network connectivity, and in the presence of brain white matter hyperintensities (WMHs) cognitive and motor impairments seem to be aggravated. However, the role of WMHs in predicting accelerating symptom worsening remains controversial. The objective was to investigate whether location and segmental brain WMH burden at baseline predict cognitive and motor declines in PD after 2 years. METHODS Ninety-eight older adults followed longitudinally from Ontario Neurodegenerative Diseases Research Initiative with PD of 3-8 years in duration were included. Percentages of WMH volumes at baseline were calculated by location (deep and periventricular) and by brain region (frontal, temporal, parietal, occipital lobes and basal ganglia + thalamus). Cognitive and motor changes were assessed from baseline to 2-year follow-up. Specifically, global cognition, attention, executive function, memory, visuospatial abilities and language were assessed as were motor symptoms evaluated using the Movement Disorder Society Unified Parkinson's Disease Rating Scale Part III, spatial-temporal gait variables, Freezing of Gait Questionnaire and Activities Specific Balance Confidence Scale. RESULTS Regression analysis adjusted for potential confounders showed that total and periventricular WMHs at baseline predicted decline in global cognition (p < 0.05). Also, total WMH burden predicted the decline of executive function (p < 0.05). Occipital WMH volumes also predicted decline in global cognition, visuomotor attention and visuospatial memory declines (p < 0.05). WMH volumes at baseline did not predict motor decline. CONCLUSION White matter hyperintensity burden at baseline predicted cognitive but not motor decline in early to mid-stage PD. The motor decline observed after 2 years in these older adults with PD is probably related to the primary neurodegenerative process than comorbid white matter pathology.

Abstract
Dual cognitive and mobility impairments are associated with an increased risk of dementia. Recent studies examining temporal trajectories of mobility and cognitive function in aging found that dual decline is associated with higher dementia risk than memory decline or gait decline only. Although initial data show that individuals with dual decline or impairment have excessive cardiovascular and metabolic risk factors, the causes of dual decline or what underlies dual decline with a high risk of dementia remain largely unknown. In December 2021, the National Institute on Aging Intramural and Extramural Programs jointly organized a workshop on Biology Underlying Moving and Thinking to explore the hypothesis that older persons with dual decline may develop dementia through a specific pathophysiological pathway. The working group discussed assessment methods for dual decline and possible mechanisms connecting dual decline with dementia risk and pinpointed the most critical questions to be addressed from a translational perspective.

Abstract
BACKGROUND Altered white matter (WM) tract integrity may contribute to mild cognitive impairment (MCI) and gait abnormalities. OBJECTIVE The purpose of this study was to determine whether diffusion tensor imaging (DTI) metrics were altered in specific portions of WM tracts in people with MCI and to determine whether gait speed variations were associated with the specific DTI metric changes. METHODS DTI was acquired in 44 people with MCI and 40 cognitively normal elderly controls (CNCs). Fractional anisotropy (FA) and radial diffusivity (RD) were measured along 18 major brain WM tracts using probabilistic tractography. The average FA and RD along the tracts were compared between the groups using MANCOVA and post-hoc tests. The tracts with FA or RD differences between the groups were examined using an along-tract exploratory analysis to identify locations that differed between the groups. Associations between FA and RD in whole tracts and in the segments of the tracts that differed between the groups and usual/dual-task gait velocities and gross cognition were examined. RESULTS Lower FA and higher RD was observed in right cingulum-cingulate gyrus endings (rh.ccg) of the MCI group compared to the CNC group. These changes were localized to the posterior portions of the rh.ccg and correlated with gait velocities. CONCLUSION Lower FA and higher RD in the posterior portion of the rh.ccg adjacent to the posterior cingulate suggests decreased microstructural integrity in the MCI group. The correlation of these metrics with gait velocities suggests an important role for this tract in maintaining normal cognitive-motor function.

Abstract
BACKGROUND The prevalence of falls and related injuries is double in older adults with cognitive impairment compared with cognitively healthy older adults. A growing body of literature shows that falls prevention interventions in the cognitively impaired are difficult to implement and that the feasibility and adherence to interventions depend on a number of factors including informal caregiver involvement. However, no systematic review exists on the topic. OBJECTIVE Our objective is to determine whether involvement of informal caregivers can reduce falls in older adults with cognitive impairment. METHODS Rapid review following Cochrane collaboration guidelines. RESULTS Seven randomized controlled trials were identified involving 2,202 participants. We identified the following areas where informal caregiving may have an important role in fall prevention in older adults with cognitive impairment: 1) enhancing adherence to the exercise program; 2) identifying and recording falls incidents and circumstances; 3) identifying and modifying possible environmental falls risk factors inside patient's home; and 4) playing an active role in modifying lifestyle in terms of diet/nutrition, limiting antipsychotics, and avoiding movements risking falls. However, informal caregiver involvement was identified as an incidental finding in these studies and the level of evidence ranged from low to moderate. CONCLUSION Informal caregiver involvement in planning and delivering interventions to reduce falls has been found to increase the adherence of individuals with cognitive impairment in falls prevention programs. Future research should address whether involvement of informal caregivers may improve efficacy of prevention programs by reducing the number of falls as a primary outcome.

Abstract
BACKGROUND Cognitive impairment is prevalent in people with lower limb amputations (PLLA) and is associated with adverse outcomes, such as falls and worse rehabilitation outcomes. Physical function tests are essential to examine abilities; however, no research in PLLA has clarified the magnitude of cognitive demands amongst available tests in users novice at walking with a prosthesis. RESEARCH QUESTION Is there an association between cognitive and physical function for PLLA novice at walking with a prosthesis? METHODS People from inpatient prosthetic rehabilitation were recruited. Inclusion criteria were: age ≥ 50 years, unilateral transtibial amputation and able to walk independently. Gait velocity and the L Test under single-task (usual) and dual-task (walking while counting backwards) conditions assessed functional mobility. The Four Square Step Test (FSST) examined dynamic balance. The Montreal Cognitive Assessment (MoCA) and the Trail Making Test (TMT-B) assessed global cognitive status and executive function, respectively. Multivariable linear regressions evaluated the association of cognition on physical function. RESULTS Twenty-two people participated (age: 62.3 ± 8.9 years, male: 68.18%). The mean MoCA score was 26.23 ± 2.90. A 1-point MoCA increase was independently associated with faster gait velocity (cm/s) [single-task: 5.45 (95%CI: 2.35-8.54, AdjR2 =0.46), dual-task: 5.04 (95%CI: 1.33-8.75, AdjR2 =0.20) and a quicker L Test (s) [single-task: - 4.75 (95%CI: 7.22-2.28, AdjR2 =0.45), dual-task: - 5.27 (95%CI: 8.74-1.80, AdjR2 =0.38)]. A 1-second TMT-B increase was also independently associated with worse L Test performance [single-task: 0.21 s (95%CI: 0.03-0.39, AdjR2 =0.20), dual-task: 0.29 s (95%CI: 0.06-0.51, AdjR2 =0.30)]. No association was observed between MoCA or TMT-B on the FSST (p > 0.13). SIGNIFICANCE Better global cognitive function and executive function were independently associated with faster gait velocity and improved functional mobility, but not dynamic balance. The present study demonstrates a unique relationship between cognition and physical function that warrants further research on the cognitive demands among clinical tests of physical function in PLLA.

Abstract
OBJECTIVE To systematically review the literature on the effect of dual-task testing on the balance and gait of people with lower limb amputations (PLLA). LITERATURE SURVEY Databases MEDLINE, EMBASE, CINAHL, PsycINFO, Web of Science, and Scopus were searched in duplicate (inception to December 1, 2020). METHODOLOGY Inclusion criteria: participants were adults with transtibial, knee-disarticulation, transfemoral, or bilateral lower limb amputations; balance or gait was paired with a secondary task; and studies were peer-reviewed and published in English. Two authors independently reviewed articles and consensus was required. A standardized data extraction sheet was used to gather study relevant information in duplicate. Methodological quality of reporting was examined using the Downs and Black Scale. A meta-analysis was unable to be performed owing to substantial participant and protocol heterogeneity among the studies included. SYNTHESIS Of 3950 articles screened, 22 met inclusion criteria. Four assessed dual-task balance and 18 dual-task gait. During single-task standing, PLLA demonstrated higher sway distance and sway velocity than controls (CN); however, a greater dual-task effect was observed only for sway velocity. Gait pace, rhythm, variability, asymmetry, and postural control were observed to be worse in PLLA relative to CN during single-task. Dual-task gait testing resulted in a disproportionally reduced pace and rhythm and increased asymmetry in PLLA compared to CN. CONCLUSIONS People with lower limb amputations have impaired balance and gait, which is affected by dual-task to a greater degree compared to healthy adults. An examination of how PLLA-specific factors such as level of amputation, reason for amputation, and experience with a prosthesis affect dual-task performance has not yet been thoroughly explored. Future research should continue to characterize the cognitive-mobility link to better understand the challenges associated with the use of a prosthesis.

Abstract
BACKGROUND/OBJECTIVES CAN-THUMBS UP is designed as a comprehensive and innovative fully remote program to 1) develop an interactive and compelling online Brain Health Support Program intervention, with potential to positively influence dementia literacy, self-efficacy and lifestyle risk factors; 2) enroll and retain a community-dwelling Platform Trial Cohort of individuals at risk of dementia who will participate in the intervention; 3) support an open platform trial to test a variety of multidomain interventions that might further benefit individuals at risk of dementia. This manuscript presents the Brain Health Support Program Study protocol. DESIGN/SETTING Twelve-month prospective multi-center longitudinal study to evaluate a fully remote web-based educational intervention. Participants will subsequently be part of a Platform Trial Cohort and may be eligible to participate in further dementia prevention clinical trials. PARTICIPANTS Three hundred fifty older adults who are cognitively unimpaired or have mild cognitive impairment, with at least 1 well established dementia risk factor. INTERVENTION Participants engage in the Brain Health Support Program intervention for 45-weeks and complete pre/post intervention measures. This intervention is designed to convey best available evidence for dementia prevention, consists of 181 chapters within 8 modules that are progressively delivered, and is available online in English and French. The program has been developed as a collaborative effort by investigators with recognized expertise in the program's content areas, along with input from older-adult citizen advisors. MEASUREMENTS This study utilizes adapted remote assessments with accessible technologies (e.g. videoconferencing, cognitive testing via computer and mobile phone, wearable devices to track physical activity and sleep, self-administered saliva sample collection). The primary outcome is change in dementia literacy, as measured by the Alzheimer's Disease Knowledge Scale. Secondary outcomes include change in self-efficacy; engagement using the online program; user satisfaction ratings; and evaluation of usability and acceptance. Exploratory outcomes include changes in attitudes toward dementia, modifiable risk factors, performance on the Neuropsychological Test Battery, performance on self-administered online cognitive assessments, and levels of physical activity and sleep; success of the national recruitment plan; and the distribution of age adjusted polygenic hazard scores. CONCLUSIONS This fully remote study provides an accessible approach to research with all study activities being completed in the participants' home environment. This approach may reduce barriers to participation, provide an easier and less demanding participant experience, and reach a broader geography with recruitment from all regions of Canada. CAN-THUMBS UP represents a Canadian contribution to the global World-Wide FINGERS program (alz.org/wwfingers).

Abstract
INTRODUCTION Understanding synergies between neurodegenerative and cerebrovascular pathologies that modify dementia presentation represents an important knowledge gap. METHODS This multi-site, longitudinal, observational cohort study recruited participants across prevalent neurodegenerative diseases and cerebrovascular disease and assessed participants comprehensively across modalities. We describe univariate and multivariate baseline features of the cohort and summarize recruitment, data collection, and curation processes. RESULTS We enrolled 520 participants across five neurodegenerative and cerebrovascular diseases. Median age was 69 years, median Montreal Cognitive Assessment score was 25, median independence in activities of daily living was 100% for basic and 93% for instrumental activities. Spousal study partners predominated; participants were often male, White, and more educated. Milder disease stages predominated, yet cohorts reflect clinical presentation. DISCUSSION Data will be shared with the global scientific community. Within-disease and disease-agnostic approaches are expected to identify markers of severity, progression, and therapy targets. Sampling characteristics also provide guidance for future study design.

Abstract
BACKGROUND Little is known about the association between executive function and the magnitude of improvement from personalised exercise interventions on gait performance among older-old adults. AIM We examined whether the effectiveness of personalised intervention on gait performance is dependent on the patient's baseline dysexecutive syndrome, as assessed by the Frontal Assessment Battery. METHODS A total of 175 older community-dwellers (83.57 ± 5.2 years; 70.2% female) were recruited from the day centre for after-care and rehabilitation in the Nantes Ambulatory Centre of the Clinical Gerontology (France), and were followed during a pre-post-intervention, single-arm retrospective design. The intervention consisted of an individual personalised rehabilitation program over a period of 7 weeks, with twice-weekly sessions (45 min each). Gait speed in four conditions (preferred, fast, and under two dual-task conditions), Timed Up and Go test, and handgrip strength test were assessed. RESULTS Using a pre-post analysis of covariance, a significant increase in dual-task gait speed while counting (+ 0.10 m/s; + 15%) and in dual-fluency gait speed (+ 0.06 m/s; + 10%), and in Timed Up and Go performance (- 2.9 s; + 17.8%) was observed after the rehabilitation program, regardless the baseline executive status. DISCUSSION An individual personalized intervention is effective to improve mobility performance and the dual-task gait speed in older-old adults. The magnitude of those effects is independent of the patient's baseline characteristics including the executive function status. CONCLUSIONS Even the most deficient baseline characteristics of patients should not be viewed as clinical barrier for implementing a beneficial individual intervention in high-risk older adults.

Abstract
Background Multidomain trials to prevent dementia by simultaneously targeting multiple risk factors with non-pharmacological lifestyle interventions show promise. Designing trials to evaluate the efficacy of individual interventions and their combinations is methodologically challenging. Determining the efficacy is, nevertheless, important to individuals, payers, and for resource allocations to support intervention implementation. Main body The central rationale for seminal trials improving cardiovascular health or reducing falls risk in older adults is that multifactorial conditions may be amenable to improvement by simultaneously targeting multiple modifiable risk factors. Similar reasoning underlies lifestyle interventions to reduce dementia risk using combinations of physical exercise, cognitive training, diet, amelioration of vascular-metabolic risk factors, and improving sleep quality. Randomizing individuals with at least two modifiable risk factors to “standardly tailored” interventions to mitigate their risk factors, versus a comparator arm, will yield an unbiased estimate of the cumulative average effect of modifying more versus fewer risk factors. The between-group difference in the cognitive primary outcome will reflect both the main effects of the mitigated risk factors, as well as their synergistic effects. However, given the positive trial results, there are inherent challenges in quantifying post hoc which components, or combination of components, were responsible for improvements in cognition. Here, we elaborate on these methodological challenges and important considerations in using a standardly tailored design with two arms (one consisting of multidomain interventions tailored to participants’ risk profiles and another consisting of active control conditions). We compare this approach to fully factorial designs and highlight the disadvantages and advantages of each. We discuss partial solutions, including analytical strategies such as risk reduction scores that measure reductions in the number or severity of risk factors in each study arm. Positive results can support the causal inference that between-group differences in the primary cognitive outcome were due to risk factor modification. Conclusion Standardly tailored designs are pragmatic and feasible evaluations of multidomain interventions to reduce dementia risk. We propose sensitivity and exploratory analyses of between-group reductions in the severity of risk factors, as a methodology to bolster causal inferences that between-group differences in the primary cognitive outcome are due to the risk factors modified.

Abstract
Alterations in tissue microstructure in normal-appearing white matter (NAWM), specifically measured by diffusion tensor imaging (DTI) fractional anisotropy (FA), have been associated with cognitive outcomes following stroke. The purpose of this study was to comprehensively compare conventional DTI measures of tissue microstructure in NAWM to diverse vascular brain lesions in people with cerebrovascular disease (CVD) and to examine associations between FA in NAWM and cerebrovascular risk factors. DTI metrics including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) were measured in cerebral tissues and cerebrovascular anomalies from 152 people with CVD participating in the Ontario Neurodegenerative Disease Research Initiative (ONDRI). Ten cerebral tissue types were segmented including NAWM, and vascular lesions including stroke, periventricular and deep white matter hyperintensities, periventricular and deep lacunar infarcts, and perivascular spaces (PVS) using T1-weighted, proton density-weighted, T2-weighted, and fluid attenuated inversion recovery MRI scans. Mean DTI metrics were measured in each tissue region using a previously developed DTI processing pipeline and compared between tissues using multivariate analysis of covariance. Associations between FA in NAWM and several CVD risk factors were also examined. DTI metrics in vascular lesions differed significantly from healthy tissue. Specifically, all tissue types had significantly different MD values, while FA was also found to be different in most tissue types. FA in NAWM was inversely related to hypertension and modified Rankin scale (mRS). This study demonstrated the differences between conventional DTI metrics, FA, MD, AD, and RD, in cerebral vascular lesions and healthy tissue types. Therefore, incorporating DTI to characterize the integrity of the tissue microstructure could help to define the extent and severity of various brain vascular anomalies. The association between FA within NAWM and clinical evaluation of hypertension and disability provides further evidence that white matter microstructural integrity is impacted by cerebrovascular function.

Abstract
BACKGROUND our aim was to assess the effectiveness of medication review and deprescribing interventions as a single intervention in falls prevention. METHODS DESIGN systematic review and meta-analysis. DATA SOURCES Medline, Embase, Cochrane CENTRAL, PsycINFO until 28 March 2022. ELIGIBILITY CRITERIA randomised controlled trials of older participants comparing any medication review or deprescribing intervention with usual care and reporting falls as an outcome. STUDY RECORDS title/abstract and full-text screening by two reviewers. RISK OF BIAS Cochrane Collaboration revised tool. DATA SYNTHESIS results reported separately for different settings and sufficiently comparable studies meta-analysed. RESULTS forty-nine heterogeneous studies were included. COMMUNITY meta-analyses of medication reviews resulted in a risk ratio (RR) of 1.05 (95% confidence interval, 0.85-1.29, I2 = 0%, 3 studies(s)) for number of fallers, in an RR = 0.95 (0.70-1.27, I2 = 37%, 3 s) for number of injurious fallers and in a rate ratio (RaR) of 0.89 (0.69-1.14, I2 = 0%, 2 s) for injurious falls. HOSPITAL meta-analyses assessing medication reviews resulted in an RR = 0.97 (0.74-1.28, I2 = 15%, 2 s) and in an RR = 0.50 (0.07-3.50, I2 = 72% %, 2 s) for number of fallers after and during admission, respectively. LONG-TERM CARE meta-analyses investigating medication reviews or deprescribing plans resulted in an RR = 0.86 (0.72-1.02, I2 = 0%, 5 s) for number of fallers and in an RaR = 0.93 (0.64-1.35, I2 = 92%, 7 s) for number of falls. CONCLUSIONS the heterogeneity of the interventions precluded us to estimate the exact effect of medication review and deprescribing as a single intervention. For future studies, more comparability is warranted. These interventions should not be implemented as a stand-alone strategy in falls prevention but included in multimodal strategies due to the multifactorial nature of falls.PROSPERO registration number: CRD42020218231.

Abstract
Background
The COVID-19 pandemic has caused significant disruption to research activities across Canada. The Training and Capacity Building (T&CB) Program of the Canadian Consortium on Neurodegeneration in Aging (CCNA) conducted a survey be-tween May 11th, 2020 and May 19th, 2020 to identify the chal-lenges faced by CCNA trainees because of the pandemic and how to best support trainees in response to those challenges.
Methods
Graduate students and postdoctoral researchers working under the supervision of CCNA investigators (n=113) were invited to complete a web-based survey of 13 questions. Trainees were asked questions about the impact of COVID-19 on their research activities, degree progression, funding status, and suggestions for support from the T&CB Program during the COVID-19 pandemic.
Results
A total of 41 trainees responded to the survey (response rate: 36.3%); 83% of respondents reported that they experienced changes to their research activities as a result of COVID-19, and 50% anticipated that their degree completion would be delayed. Respondents requested information from the T&CB Program on funding for non-COVID-19 projects, alternative datasets, and short educational workshops.
Conclusion
The majority of CCNA trainees surveyed experienced sig-nificant changes to their research activities as a result of the COVID-19 pandemic. The T&CB Program responded by switching to online programming and facilitating remote research. Further engagement with trainees is needed to ensure continued progress of research in age-related neurodegenera-tive disease in Canada post-pandemic.

Abstract
BACKGROUND falls and fall-related injuries are common in older adults, have negative effects on functional independence and quality of life and are associated with increased morbidity, mortality and health related costs. Current guidelines are inconsistent, with no up-to-date, globally applicable ones present. OBJECTIVES to create a set of evidence- and expert consensus-based falls prevention and management recommendations applicable to older adults for use by healthcare and other professionals that consider: (i) a person-centred approach that includes the perspectives of older adults with lived experience, caregivers and other stakeholders; (ii) gaps in previous guidelines; (iii) recent developments in e-health and (iv) implementation across locations with limited access to resources such as low- and middle-income countries. METHODS a steering committee and a worldwide multidisciplinary group of experts and stakeholders, including older adults, were assembled. Geriatrics and gerontological societies were represented. Using a modified Delphi process, recommendations from 11 topic-specific working groups (WGs), 10 ad-hoc WGs and a WG dealing with the perspectives of older adults were reviewed and refined. The final recommendations were determined by voting. RECOMMENDATIONS all older adults should be advised on falls prevention and physical activity. Opportunistic case finding for falls risk is recommended for community-dwelling older adults. Those considered at high risk should be offered a comprehensive multifactorial falls risk assessment with a view to co-design and implement personalised multidomain interventions. Other recommendations cover details of assessment and intervention components and combinations, and recommendations for specific settings and populations. CONCLUSIONS the core set of recommendations provided will require flexible implementation strategies that consider both local context and resources.

Abstract
Few large nationwide studies have investigated the relationship between shiftwork and cognitive performance, and little is known about whether and how psychological distress may impact this relationship. This study aimed to examine: (1) the cross-sectional relationship between shiftwork (yes/no) and some aspects of cognitive performance (declarative memory and executive functioning) and (2) the potential moderating effect of psychological distress among 20,610 community-dwelling adults from the comprehensive cohort of the Canadian Longitudinal Study on Aging (CLSA). Differences by sex and retirement status were also explored. Shiftwork was significantly associated with poorer performance for executive functioning (interference condition: ß = 0.47, 95% CI: 0.31 to 0.63; MAT: ß = -0.85, 95% CI: -1.21 to -0.50) but not for declarative memory. Completely and not/partly retired males showed poorer cognitive performance on executive functioning. However, no evidence of a moderating effect by psychological distress was found. Our findings confirm the association between shiftwork and cognitive performance and highlight important health correlates of shiftwork.

Abstract
Background To review the validated instruments that assess gait, balance, and functional mobility to predict falls in older adults across different settings. Methods Umbrella review of narrative- and systematic reviews with or without meta-analyses of all study types. Reviews that focused on older adults in any settings and included validated instruments assessing gait, balance, and functional mobility were included. Medical and allied health professional databases (MEDLINE, PsychINFO, Embase, and Cochrane) were searched from inception to April 2022. Two reviewers undertook title, abstract, and full text screening independently. Review quality was assessed through the Risk of Bias Assessment Tool for Systematic Reviews (ROBIS). Data extraction was completed in duplicate using a standardised spreadsheet and a narrative synthesis presented for each assessment tool. Results Among 2736 articles initially identified, 31 reviews were included; 11 were meta-analyses. Reviews were primarily of low quality, thus at high risk of potential bias. The most frequently reported assessments were: Timed Up and Go, Berg Balance Scale, gait speed, dual task assessments, single leg stance, functional Reach Test, tandem gait and stance and the chair stand test. Findings on the predictive ability of these tests were inconsistent across the reviews. Conclusions In conclusion, we found that no single gait, balance or functional mobility assessment in isolation can be used to predict fall risk in older adults with high certainty. Moderate evidence suggests gait speed can be useful in predicting falls and might be included as part of a comprehensive evaluation for older adults. Supplementary Information The online version contains supplementary material available at 10.1186/s12877-022-03271-5.

Abstract
OBJECTIVE To compare the effects of a multicomponent exercise program and a dual-task exercise program on the number of falls (fall rate) and number of fallers (fall incidence) and on parameters associated with fall risk in older adults living in long-term nursing homes (LTNH). STUDY DESIGN This is a secondary analysis of a single-blind randomized controlled trial involving 85 older adults in nine LTNHs (Gipuzkoa, Spain). Participants allocated to the multicomponent group underwent a twice-a-week 3-month individualized and progressive resistance and balance program. The dual-task group performed simultaneous cognitive training with the same multicomponent exercises. MAIN OUTCOMES Fall rate and incidence were analyzed using Poisson regression (adjusting for cognitive function and previous fall rate) and Kaplan-Meier analysis, respectively. Handgrip asymmetry, single- and dual-task TUG velocity and cost were assessed using two-way ANOVA for repeated measures and paired Student's t-tests. RESULTS The dual-task group showed a 3.8 times greater risk of falling than the multicomponent group during the intervention, and a 2.59 times greater risk during the 12-month follow-up. There were no between-group differences in fall incidence. There were between-group differences in handgrip strength asymmetry in favor of the multicomponent group. While only the multicomponent group improved on the TUG test, the dual-task group improved on dual-task cost. CONCLUSIONS Compared with the dual-task program, the multicomponent exercise program showed more benefits in reducing falls and in parameters associated with fall risk in LTNH residents. Future studies are warranted to confirm our results and continue to explore physical and cognitive interventions to prevent falls in LTNHs.

Abstract
IMPORTANCE Older adults with mild cognitive impairment (MCI) have the highest risk of progressing to dementia. Evidence suggests that nonpharmacological, single-domain interventions can prevent or delay progressive declines, but it is unclear whether greater cognitive benefits arise from multidomain interventions. OBJECTIVE To determine whether multidomain interventions, composed of 2 or more interventions, are associated with greater improvements in cognition among older adults with MCI than a single intervention on its own. DATA SOURCES MEDLINE, Embase, PsycInfo, AgeLine, CINAHL, and Cochrane Central Register of Controlled Trials were systematically searched from database inception to December 20, 2021. STUDY SELECTION Included studies contained (1) an MCI diagnosis; (2) nonpharmacological, multidomain interventions that were compared with a single active control; (3) older adults aged 65 years and older; and (4) randomized clinical trials. DATA EXTRACTION AND SYNTHESIS Data were screened and extracted by 3 independent reviewers. Following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, random-effects meta-analyses were used to calculate effect sizes from the standardized mean difference (SMD) and 95% CIs. MAIN OUTCOMES AND MEASURES Postintervention cognitive test scores in 7 cognitive domains were compared between single-domain and multidomain groups. Exposure to the intervention was analyzed. RESULTS A total of 28 studies published between 2011 and 2021, including 2711 older adults with MCI, reported greater effect sizes in the multidomain group for global cognition (SMD, 0.41; 95% CI, 0.23-0.59; P < .001), executive function (SMD, 0.20; 95% CI, 0.04-0.36; P = .01), memory (SMD, 0.29; 95% CI, 0.14-0.45; P < .001), and verbal fluency (SMD, 0.30; 95% CI, 0.12-0.49; P = .001). The Mini-Mental State Examination (SMD, 0.40; 95% CI, 0.17-0.64; P < .001), category verbal fluency test (SMD, 0.34; 95% CI, 0.13-0.56; P = .002), Trail Making Test-B (SMD, 0.46; 95% CI, 0.13-0.80; P = .007), and Wechsler Memory Scale-Logical Memory I (SMD, 0.47; 95% CI, 0.15-0.80; P < .001) and II (SMD, 0.26; 95% CI, 0.07-0.45; P < .001) favored the multidomain group. Exposure to the intervention varied between studies: the mean (SD) duration was 71.3 (36.0) minutes for 19.8 (14.6) weeks with sessions taking place 2.5 (1.1) times per week, and all interventions lasted less than 1 year. CONCLUSIONS AND RELEVANCE In this study, short-term multidomain interventions (<1 year) were associated with improvements in global cognition, executive function, memory, and verbal fluency compared with single interventions in older adults with MCI.

Abstract
PURPOSE Medication use, and gait impairment are two major risk factors for falls in older adults. There are several mechanisms linking fall risk-increasing drugs (FRIDs) and increased fall risk. One pathway involves gait performance as an intermediate variable. It is plausible that FRIDs indirectly increase fall risk by causing gait impairment. The purpose of this review was to systematically review the existing evidence on the association between FRIDs and gait performance in community-dwelling older adults without neurological movement disorders. METHODS Two searches were performed using MeSH terms and keywords in the electronic databases MEDLINE, EMBASE, PsycINFO, CINAHL and grey literature. We included clinical trials and observational studies that assessed the association between a FRID class and any quantitative measure of gait performance. Quality assessment was performed using the Newcastle-Ottawa scale for observational studies and the Cochrane risk-of-bias tool for clinical trials. Study characteristics and findings were summarized in a descriptive approach for each drug class. RESULTS A total of 11,197 studies were retrieved from both searches at the first step and a total of 23 studies met the final inclusion criteria. Fourteen studies assessed the association between psychotropic FRIDs and gait performance and nine assessed cardiovascular FRIDs. Four out of five studies found that drugs with sedative properties are associated with reduced gait speed in older adults. Three out of four studies found no association between statin use and gait speed. There is insufficient evidence on the association between FRIDs and other gait performance measures. CONCLUSION Caution should be taken when prescribing drugs with sedative properties to older adults at risk of falls. Further research is required to assess the impact of the use FRIDs on gait performance measures other than gait speed.

Abstract
Change in empathy is an increasingly recognised symptom of neurodegenerative diseases and contributes to caregiver burden and patient distress. Empathy impairment has been associated with brain atrophy but its relationship to white matter hyperintensities (WMH) is unknown. We aimed to investigate the relationships amongst WMH, brain atrophy, and empathy deficits in neurodegenerative and cerebrovascular diseases. Five hundred thirteen participants with Alzheimer's disease/mild cognitive impairment, amyotrophic lateral sclerosis, frontotemporal dementia (FTD), Parkinson's disease, or cerebrovascular disease (CVD) were included. Empathy was assessed using the Interpersonal Reactivity Index. WMH were measured using a semi-automatic segmentation and FreeSurfer was used to measure cortical thickness. A heterogeneous pattern of cortical thinning was found between groups, with FTD showing thinning in frontotemporal regions and CVD in left superior parietal, left insula, and left postcentral. Results from both univariate and multivariate analyses revealed that several variables were associated with empathy, particularly cortical thickness in the fronto-insulo-temporal and cingulate regions, sex (female), global cognition, and right parietal and occipital WMH. Our results suggest that cortical atrophy and WMH may be associated with empathy deficits in neurodegenerative and cerebrovascular diseases. Future work should consider investigating the longitudinal effects of WMH and atrophy on empathy deficits in neurodegenerative and cerebrovascular diseases.

Abstract
BACKGROUND Mild behavioral impairment (MBI) and dual-task gait cost (DTGC) are two non-cognitive markers of dementia that capture behavioral and motor symptoms. We investigated the relationship between MBI and DTGC in a sample of non-demented older adults. METHODS This was a cross-sectional observational study of 193 participants (10 cognitively normal, 48 subjective cognitive decline (SCD), 135 mild cognitive impairment (MCI); 52.8% female) from 13 Canadian sites from the Comprehensive Assessment of Neurodegeneration and Dementia (COMPASS-ND) study. The Neuropsychiatric Inventory Questionnaire (NPI-Q) was used to define MBI severity using a published algorithm. DTGC, the percentage difference between dual-task and preferred walking speeds, was assessed under three cognitive tasks: animal naming, counting backwards, and serial seven subtractions. Associations were tested in the entire cohort and in the MCI subgroup using multivariable linear regression adjusted for age, sex, education, and diagnosis. The role of global cognition, executive function, verbal and working memory in the association were investigated using tests of mediation and moderation. RESULTS MBI symptoms were present in 46.6% of participants (mean age = 72.4 years). Greater overall MBI burden was associated with lower gait speed across all conditions. Furthermore, a one-point increase in global MBI symptom severity was associated with a 0.8% increase in DTGC in the animal fluency condition, a 0.9% increase in the counting backwards condition and a 1.1% increase in the serial sevens condition. These associations were strongest in the subgroup of MCI participants. Executive function but not global cognition or verbal and working memory mediated the association between MBI and DTGC in all three conditions. CONCLUSIONS MBI is associated with gait speed and DTGC in this group of non-demented individuals, independent of the presence or absence of MCI. These findings provide evidence of the relationship between these non-cognitive dementia markers of behavior and gait beyond cognitive impairment.

Abstract
BACKGROUND Hospitalization is a moment of extreme vulnerability for frail older adults. There is scarce evidence on the effectiveness of geriatric co-management or transitional care interventions in Latin America. AIMS To assess whether geriatric co-management combined with an interdisciplinary transitional care intervention could reduce 30-day hospital readmission rate compared to usual care in hospitalized frail older patients in a tertiary hospital in Argentina. METHODS Single-blinded randomized controlled trial. Usual care treatment arm: all procedures performed during hospitalization were overseen by a senior internal medicine specialist and complied with pre-defined protocols. Patients had access to specialist care if needed, as well as hospital-at-home or home-based primary care services after discharge. Intervention treatment arm: in addition to usual care, a geriatric co-management team performed a comprehensive geriatric assessment during hospitalization, provided tailored recommendations to minimize geriatric syndromes and planned transition of care. A health and social care counselor oversaw continuity of care in patients' homes after discharge. RESULTS We included 120 participants in each of the intervention and usual care (control) arms. Thirty-day hospital readmissions were 47.7% lower in the intervention arm (18.3% vs 35.0%; P = 0.040); and emergency room visits within the first 6 months after discharge were 27.8% lower (43.3% vs 60.0%; P = 0.010). There was a non-statistically significant decrease in 6-month mortality in the intervention arm (25.0% vs 35.0%; P = 0.124). CONCLUSION Geriatric co-management of frail older patients during hospitalization combined with an interdisciplinary transitional care intervention reduced 30-day hospital readmissions and emergency visits 6 months after discharge. TRIAL REGISTRATION NUMBER Trial registration number: RENIS IS003081.

Abstract
BACKGROUND Altered gait is a frequent feature of Alzheimer's disease (AD), as is vitamin D deficiency. Treatment with memantine and vitamin D can protect cortical axons from exposure to amyloid-β and glutamate toxicity, suggesting this combination may mitigate altered gait in AD. OBJECTIVE Investigate the effects of vitamin D deprivation and subsequent treatment with memantine and vitamin D enrichment on gait performance in APPswe/PS1dE9 mice. METHODS Male APPswe/PS1dE9 mice were split into four groups (n = 14 each) at 2.5 months of age. A control group was fed a standard diet throughout while the other three groups started a vitamin D-deficient diet at month 6. One group remained on this deficient diet for the rest of the study. At month 9, the other two groups began treatment with either memantine alone or memantine combined with 10 IU/g of vitamin D. Gait was assessed using CatWalk at months 6, 9, 12, and 15. RESULTS Vitamin D deprivation led to a 13% increase in hind stride width by month 15 (p < 0.001). Examination of the treatment groups at month 15 revealed that mice treated with memantine alone still showed an increase in hind stride width compared to controls (p < 0.01), while mice treated with memantine and vitamin D did not (p = 0.21). CONCLUSION Vitamin D deprivation led to impaired postural control in the APPswe/PS1dE9 model. Treatment with memantine and vitamin D, but not memantine alone, prevented this impairment. Future work should explore the potential for treatments incorporating vitamin D supplementation to improve gait in people with AD.

Abstract
Alzheimer’s disease is a major cause of morbidity and mortality. Currently, there are no disease-modifying pharmacotherapies for this condition. Aducanumab, an amyloid beta-directed monoclonal antibody that targets aggregated forms of amyloid-beta in the brains of people with Alzheimer’s disease, has raised hopes that such a therapy has been discovered, but its approval by the US Food and Drug Administration has engendered a good deal of controversy. A similar application for approval has been submitted to Health Canada. In response to this, a group of Canadian clinical dementia experts representing a number of organizations, including the Canadian Geriatrics Society, was convened by the Canadian Consortium on Neurodegeneration in Aging (CCNA) to discuss the evidence currently available on this agent and seek consensus on what advice they would offer Health Canada on the application. There was wide-spread agreement that it would be premature for aducanumab to receive approval for the treatment of Alzheimer’s disease. It was also noted that the Canadian health-care system is poorly prepared at this time to deal with a disease-modifying therapeutic with targeting, administration, and monitoring characteristics like aducanumab. In this paper, the consensus reached is presented along with its underlying rationale.

Abstract
BACKGROUND Adverse drug reactions are a common cause of potentially avoidable harm, particularly in older adults. AIMS To evaluate the feasibility and efficacy of a pilot multifactorial intervention to reduce potentially inappropriate medication (PIM) use in older adults. METHODS We conducted a phase 2, feasibility, open-label study in the ambulatory setting of an integrated healthcare network in Buenos Aires, Argentina. We recruited primary care physicians (PCPs) and measured PIM use in a sample of their patients (65 years or older). Educational workshops for PCPs were organized with the involvement of clinician champions. Practical deprescribing algorithms were designed based on Beers criteria. Automatic email alerts based on specific PIMs recorded in each patient's electronic health record were used as a reminder tool. PCPs were responsible for deprescribing decisions. We randomly sampled 879 patients taking PIMs from eight of the most commonly used drug classes at our institution and compared basal (6 months prior to the intervention) and final (12 months after) prevalence of PIM use using a test of proportions. RESULTS There was a significant reduction (p < 0.05) in all drug classes evaluated. Non-Steroidal Anti-Inflammatory Drugs (basal prevalence 5.92%; final 1.59%); benzodiazepines (10.13%; 6.94%); histamine antagonists (7.74%; 3.07%); opioids (2.16%; 1.25%); tricyclic antidepressants (8.08%; 4.10%); muscle relaxants (7.74%; 3.41%), anti-hypertensives (3.53%; 1.82%) and oxybutynin (2.96%; 1.82%). The absolute reduction in the overall prevalence was 8.5 percentage points (relative reduction of 51.4%). CONCLUSION This multifactorial intervention is feasible and effective in reducing the use of potentially inappropriate medication in all drug classes evaluated.

Abstract
BACKGROUND People with advanced dementia often exhibit responsive behaviors such as apathy, depression, agitation, aggression, and psychosis. Non-pharmacological approaches (e.g., listening to music, watching television, doing arts and crafts) are now considered as a first-line strategy to manage responsive behaviors in clinical practice due to the potential risks associated with the antipsychotic medications. To date, no evaluations of immersive non-head mounted virtual reality (VR) experience as a non-pharmacologic approach for people with advanced dementia living in nursing homes have been reported. OBJECTIVE To evaluate the feasibility (acceptance and safety) of VR experience. METHODS A single site case series (nonrandomized and unblinded) with a convenience sample (N = 24; age = 85.8±8.6 years; Cognitive Performance Scale score = 3.4±0.6) measuring depression and agitation before and after the intervention. The intervention was a 30-min long research coordinator- facilitated VR experience for two weeks (10 sessions). RESULTS The intervention was feasible (attrition rate = 0% ; adverse events = 0). A reduction in depression and in agitation was observed after the intervention. However, we suggest extreme caution in interpreting this result considering the study design and small sample size. CONCLUSION This study provides the basis for conducting a randomized controlled trial to evaluate the effect of VR experience on responsive behaviors in nursing homes. Since our intervention uses a smart remote-controlled projector without a headset, infectious exposure can be avoided following the COVID-19 pandemic-induced physical distancing policy in care homes.

Abstract
BACKGROUND Studies have shown benefits of exercise interventions on preferred and fast gait speed in healthy older adults, but the impact of a personalised rehabilitation program targeting a large cohort of non-disabled older-old adults has rarely been examined. AIMS The purpose was to determine whether personalised intervention-related improvements in gait and mobility performance in older-old adults were dependent on cognitive status and/or history of falls. METHODS Based on a pre-post design, 483 older-old persons (mean age: 83.3 ± 5.1 years) were followed during a personalised rehabilitation program over a period of 7 weeks, with twice-weekly sessions (45 min each). Gait speed in four conditions (preferred, fast, and under two dual-task conditions), static postural sway, Timed Up and Go test, Five Times Sit to Stand test, the ability to rise from the floor, and handgrip strength test were assessed. RESULTS Using a pre-post analysis of covariance, a significant increase in preferred gait speed (+ 20.1%), fast gait speed (+ 15.8%), and dual-task speed while counting (+ 13.4%) was observed after the rehabilitation, regardless of the baseline cognitive status and fall history. Similar improvements in TUG and maximal handgrip force were observed, with a significant reduction of performance time (-19.5%) or an increase of handgrip strength (+ 6.2%). DISCUSSION Results suggest the effectiveness of personalised intervention to improve a battery of physical performance measures in older-old adults, even for the frailest participants. CONCLUSION Implementing a personalised intervention for targeting the high-risk older-old adults in priority is critical regarding the clinically meaningful change in gait speed.

Abstract
BACKGROUND Low socioeconomic status has been associated with individual health-related problems; however, no study has specifically investigated the impact of socioeconomic disparities on gait performance using an index that considers the population aggregation, as the Human Development Index (HDI). Thus, the aim of the present study was to assess gait parameters of older people living in cities with differences in socioeconomic conditions, identified by HDI. METHODS Cross-sectional design study conducted with a sample of 233 older people from two Brazilians regions: Coari, state of Amazonas, Brazil (n= 124, low-HDI-Bra) and Ribeirão Preto, state of São Paulo, Brazil (n= 109, very high-HDI-Bra). The gait performance was assessed by an electronic walkway, and the interest variables were gait speed, cadence, stride time, step length and stride width. RESULTS Low-HDI-Bra group presented worse gait performance as identified by slower gait speed (p = < .001), slower cadence (p = < .001), higher stride time (p = < .001), shorter step length (p = < .001), compared with the very high-HDI-Bra group. There was a positive association between HDI, and gait spend, cadence and step length, and there was a negative association between HDI and stride time and stride width. CONCLUSIONS Long-term exposure to socioeconomic inequalities found in low HDI cities may impair gait performance in late life. Such information may be relevant to create public politics that use the gait parameter based on the region where the people live.

Abstract
BACKGROUND Vitamin D deficiency and altered body composition are common in Alzheimer's disease (AD). Memantine with vitamin D supplementation can protect cortical axons against amyloid-β exposure and glutamate toxicity. OBJECTIVE To study the effects of vitamin D deprivation and subsequent treatment with memantine and vitamin D enrichment on whole-body composition using a mouse model of AD. METHODS Male APPswe/PS1dE9 mice were divided into four groups at 2.5 months of age: the control group (n = 14) was fed a standard diet throughout; the remaining mice were started on a vitamin D-deficient diet at month 6. The vitamin D-deficient group (n = 14) remained on the vitamin D-deficient diet for the rest of the study. Of the remaining two groups, one had memantine (n = 14), while the other had both memantine and 10 IU/g vitamin D (n = 14), added to their diet at month 9. Serum 25(OH)D levels measured at months 6, 9, 12, and 15 confirmed vitamin D levels were lower in mice on vitamin D-deficient diets and higher in the vitamin D-supplemented mice. Micro-computed tomography was performed at month 15 to determine whole-body composition. RESULTS In mice deprived of vitamin D, memantine increased bone mineral content (8.7% increase, p < 0.01) and absolute skeletal tissue mass (9.3% increase, p < 0.05) and volume (9.2% increase, p < 0.05) relative to controls. This was not observed when memantine treatment was combined with vitamin D enrichment. CONCLUSION Combination treatment of vitamin D and memantine had no negative effects on body composition. Future studies should clarify whether vitamin D status impacts the effects of memantine treatment on bone physiology in people with AD.

Abstract
BACKGROUND falls and fall-related injuries are common in older adults, have negative effects both on quality of life and functional independence and are associated with increased morbidity, mortality and health care costs. Current clinical approaches and advice from falls guidelines vary substantially between countries and settings, warranting a standardised approach. At the first World Congress on Falls and Postural Instability in Kuala Lumpur, Malaysia, in December 2019, a worldwide task force of experts in falls in older adults, committed to achieving a global consensus on updating clinical practice guidelines for falls prevention and management by incorporating current and emerging evidence in falls research. Moreover, the importance of taking a person-centred approach and including perspectives from patients, caregivers and other stakeholders was recognised as important components of this endeavour. Finally, the need to specifically include recent developments in e-health was acknowledged, as well as the importance of addressing differences between settings and including developing countries. METHODS a steering committee was assembled and 10 working Groups were created to provide preliminary evidence-based recommendations. A cross-cutting theme on patient's perspective was also created. In addition, a worldwide multidisciplinary group of experts and stakeholders, to review the proposed recommendations and to participate in a Delphi process to achieve consensus for the final recommendations, was brought together. CONCLUSION in this New Horizons article, the global challenges in falls prevention are depicted, the goals of the worldwide task force are summarised and the conceptual framework for development of a global falls prevention and management guideline is presented.

Abstract
Although the current low workforce availability of care of the elderly (COE) physicians, geriatric medicine specialists, and geriatric psychiatrists is undeniable, the ongoing demographic shift means this situation will only worsen. This evolving crisis is outlined clearly in the article "Updated Inventory and Projected Requirements for Specialist Physicians in Geriatrics" by Basu et al. found in this issue of the Canadian Geriatrics Journal.

Abstract
The purpose of this study was to test the feasibility of delivering Improvised Active Music Therapy sessions in measuring the impact of acquisition of rhythmic complexity levels on gait performance in individuals with Parkinson’s disease. In this single subject multiple baseline design, the study measured the ability of three right-handed participants with Parkinson’s disease to acquire greater density of syncopation, as a measure of rhythmic complexity levels, while playing uninterrupted improvised music on a simplified electronic drum-set. The music content of the sessions was transformed into digital music data in real-time using Musical Instrument Digital Interface. The Musical Instrument Digital Interface data were analyzed to determine the participants’ and the Music Therapist’s density of syncopation (on acoustic guitar) during baseline and treatment conditions. Results from visual analyses and Pearson’s correlations on the outcomes indicated conflicting and inconclusive outcomes about whether higher acquisition of rhythmic complexity levels improves gait performance in individuals with Parkinson’s disease. Despite this, evidence was found to support the overall value of Improvised Active Music Therapy sessions on gait performance. The study design, the intervention, and outcome measures were found to be feasible and could be scaled-up into a larger trial.

Abstract
Identification of biological changes underlying the early symptoms of Alzheimer's disease (AD) will help to identify and stage individuals prior to symptom onset. The limbic system, which supports episodic memory and is impaired early in AD, is a primary target. In this study, brain metabolism and microstructure evaluated by high field (7 Tesla) proton magnetic resonance spectroscopy (1H-MRS) and diffusion tensor imaging (DTI) were evaluated in the limbic system of eight individuals with mild cognitive impairment (MCI), nine with AD, and sixteen normal elderly controls (NEC). Left hippocampal glutamate and posterior cingulate N-acetyl aspartate concentrations were reduced in MCI and AD compared to NEC. Differences in DTI metrics indicated volume and white matter loss along the cingulum in AD compared to NEC. Metabolic and microstructural changes were associated with episodic memory performance assessed using Craft Story 21 Recall and Benson Complex Figure Copy. The current study suggests that metabolite concentrations measured using 1H-MRS may provide insight into the underlying metabolic and microstructural processes of episodic memory impairment.
