Abstract
Background Quality of life (QOL) and treatment needs of patients with dementia with Lewy bodies (DLB) and their caregivers are important factors to consider when developing treatment strategies. Objective To investigate factors associated with QOL in patients with DLB, and to examine factors associated with activities of daily living (ADL) if ADL was associated with QOL. Methods We previously conducted a questionnaire survey study to investigate the treatment needs of patients with DLB and their caregivers. This pre-specified additional analysis evaluated the Physical Component Score (PCS) and Mental Component Score (MCS) of the Short Form-8 for QOL, and the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part II total score for ADL. Results In total, 231 patient- caregiver pairs and 38 physicians were included. Multivariable analysis of QOL showed that the MDS-UPDRS Part II total score (standard regression coefficient [β], - 0.432) was associated with the PCS, and presence of depression (β, - 0.330) was associated with the MCS. The severity of postural instability/gait disorder (PIGD) (β, 0.337) and rigidity (β, 0.266), presence of hallucinations (β, 0.165), male sex (β, 0.157), and use of "short stay" or "small-scale, multifunctional home care" (β, 0.156) were associated with worsened ADL. Conclusions In patients with DLB, QOL was negatively impacted by severity of ADL disability and depression, and ADL was negatively impacted by severity of PIGD and rigidity, hallucinations, male sex, and use of "short stay" or "small-scale, multifunctional home care."

Abstract
INTRODUCTION People caring for patients with dementia are prone to suffering from burden. Behavioral and psychological symptoms of dementia (BPSD) may have an impact on caregiver burden. In Latin American countries, there is a lack of research on caregiver burden. We aimed to determine which BPSD have the greatest impact on caregiver burden among Peruvian patients with dementia and to compare the effects of BPSD on caregiver burden across different types of dementia. METHODS A cross-sectional study was conducted on 231 patients living with Alzheimer's dementia (AD), behavioral variant frontotemporal dementia (bvFTD), dementia with Lewy bodies (DLB), and vascular dementia (VD) and their caregivers who attended a Peruvian memory clinic. BPSD were assessed with the Neuropsychiatric Inventory (NPI). Caregiver burden was assessed with the Zarit Burden Inventory. We used analysis of variance to compare the AD, bvFTD, DLB, and VD groups. Correlations between Zarit Burden Inventory and NPI subscale scores were assessed with Spearman's correlation. RESULTS DLB caregivers had significantly higher levels of burden than the other patient groups (p < 0.05) and higher total NPI scores than caregivers for other patient groups (p < 0.05). bvFTD caregivers had significantly higher total NPI scores than AD and VD caregivers (p < 0.05). Hallucinations, aberrant motor behavior, and apathy were the symptoms most significantly correlated with caregiver burden in those caring for DLB, bvFTD, and AD patients, respectively. CONCLUSION Neuropsychiatric symptoms are higher in DLB caregivers. Hallucinations, aberrant motor behavior, and apathy are the main symptoms correlated with burden.

Psychogeriatrics 2024; 24:589-596. [PMID: 38439217 DOI: 10.1111/psyg.13101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 02/15/2024] [Indexed: 03/06/2024]
Abstract
BACKGROUND Current evidence for the management of symptoms associated with dementia with Lewy bodies (DLB) using donepezil is limited. We conducted a meta-analysis of three randomised controlled trials of donepezil in patients with DLB to investigate the overall efficacy of donepezil on Mini-Mental State Examination (MMSE), Neuropsychiatric Inventory (NPI), and Clinician's Interview-Based Impression of Change-plus Caregiver Input (CIBIC-plus). METHODS A meta-analysis was performed using the data of 312 patients administered placebo or 10 mg donepezil. Overall mean score differences for MMSE, NPI-2, and NPI-10 from baseline to week 12 and their 95% confidence intervals (CI) were estimated. For CIBIC-plus, which was transformed from a seven-point grade to a dichotomous outcome (improvements/no improvements), odds ratio (OR) and its 95% CI were estimated. Random-effects models were used, and heterogeneity was evaluated using the Cochrane's Q test and I2 statistic. RESULTS Heterogeneity was suspected for NPI-2 (P < 0.05; I2 = 87.2%) and NPI-10 (P < 0.05; I2 = 67.7%) while it was not suspected for MMSE (P = 0.23; I2 = 32.4%) and CIBIC-plus (P = 0.26; I2 = 19.8%). The overall mean MMSE score difference (mean difference: 1.50; 95% CI, 0.67-2.34) and the overall odds of improving CIBIC-plus (OR: 2.20; 95% CI, 1.13-4.26) from baseline to week 12 were higher in the donepezil group than in the placebo group. CONCLUSION Results of our meta-analysis indicated overall efficacy of donepezil on cognitive impairment and global clinical status in patients with DLB.

Abstract
BACKGROUND Donepezil has been approved in Japan for the treatment of dementia with Lewy bodies (DLB) based on clinical trials showing its beneficial effects on cognitive impairment. This phase IV study evaluated the efficacy of donepezil by focusing on global clinical status during a 12-week double-blind phase. METHODS Patients with probable DLB were randomly assigned to the placebo (n = 79) or 10 mg donepezil (n = 81) groups. The primary endpoint was changes in global clinical status, assessed using the Clinician's Interview-Based Impression of Change plus Caregiver Input (CIBIC-plus). We also assessed four CIBIC-plus domains (general condition, cognitive function, behaviour, and activities of daily living) and changes in cognitive impairment and behavioural and neuropsychiatric symptoms measured using the Mini-Mental State Examination (MMSE) and the Neuropsychiatric Inventory (NPI), respectively. RESULTS Although donepezil's superiority was not shown in the global clinical status, a significant favourable effect was detected in the cognitive domain (P = 0.006). MMSE scores improved in the donepezil group after adjustments in post hoc analysis (MMSE mean difference, 1.4 (95% confidence interval (CI), 0.42-2.30), P = 0.004). Improvements in NPIs were similar between the groups (NPI-2: -0.2 (95% CI, -1.48 to 1.01), P = 0.710; NPI-10: 0.1 (95% CI, -3.28 to 3.55), P = 0.937). CONCLUSION The results support the observation that the efficacy of 10 mg donepezil in improving cognitive function is clinically meaningful in DLB patients. The evaluation of global clinical status might be affected by mild to moderate DLB patients enrolled in this study. No new safety concerns were detected.

Abstract
BACKGROUND AND PURPOSE Visual hallucinations are a common, potentially distressing experience of people with Lewy body disease (LBD). The underlying brain changes giving rise to visual hallucinations are not fully understood, although previous models have posited that alterations in the connectivity between brain regions involved in attention and visual processing are critical. METHODS Data from 41 people with LBD and visual hallucinations, 48 with LBD without visual hallucinations and 60 similarly aged healthy comparator participants were used. Connections were investigated between regions in the visual cortex and ventral attention, dorsal attention and default mode networks. RESULTS Participants with visual hallucinations had worse cognition and motor function than those without visual hallucinations. In those with visual hallucinations, reduced functional connectivity within the ventral attention network and from the visual to default mode network was found. Connectivity strength between the visual and default mode network correlated with the number of correct responses on a pareidolia task, and connectivity within the ventral attention network with visuospatial performance. CONCLUSIONS Our results add to evidence of dysfunctional connectivity in the visual and attentional networks in those with LBD and visual hallucinations.

Abstract
Background and Purpose: Caring for someone with Lewy body disease (LBD) is difficult. This study describes the development and validity testing of the LBD Caregiver Activities Scale (LBD-CAS). Methods: Caregiver interviews informed the development of the LBD-CAS. Experts estimated the content validity of items (I-CVI) and provided feedback about the scale. Family caregivers evaluated items for face validity. Results: Expert I-CVI ratings yielded 49 items with scores of 0.83 or higher. Four items with I-CVI scores <.83 were retained due to conceptual significance. The overall scale CVI was 0.86. Items evaluated by caregivers for face validity showed excellent variability in responses, with no major ceiling or floor effects. Conclusions: LBD-CAS showed evidence of content and face validity for the assessment of activities performed by LBD caregivers. Further psychometric testing is recommended.

Abstract
Dementia with Lewy bodies and Parkinson's disease dementia are common neurodegenerative diseases that share similar neuropathological profiles and spectra of clinical symptoms but are primarily differentiated by the order in which symptoms manifest. The question of whether a distinct molecular pathological profile could distinguish these disorders is yet to be answered. However, in recent years, studies have begun to investigate genomic, epigenomic, transcriptomic and proteomic differences that may differentiate these disorders, providing novel insights in to disease etiology. In this review, we present an overview of the clinical and pathological hallmarks of Lewy body dementias before summarizing relevant research into genetic, epigenetic, transcriptional and protein signatures in these diseases, with a particular interest in those resolving "omic" level changes. We conclude by suggesting future research directions to address current gaps and questions present within the field.

Abstract
INTRODUCTION Dementia with Lewy bodies (DLB) is an incurable form of dementia associated with detriments to the daily life of patients and carers from their family. Symptoms of orthostatic hypotension, syncope, and falls are supportive of DLB diagnosis. These symptoms may also be present among people with sick sinus syndrome (SSS), and subsequent pacemaker treatment to manage bradyarrhythmia is associated with improved cognitive function. The prevalence of SSS seems to be higher among people with underlying Lewy body pathology compared to the general age-matched population (5.2% vs. 0.17%). To our knowledge, how people with DLB and their family carers may experience pacemaker treatment to manage bradyarrhythmia has not been previously reported. Therefore, the aim of this study was to explore how people with DLB experience daily life following a pacemaker implant to manage associated symptoms of bradyarrhythmia. METHODS A qualitative case study design was used. Two men with DLB and their spouse carers were repeatedly interviewed as a dyad within 1 year following implant of a dual-chamber rate-adaptive (DDD-CLS) pacemaker to manage SSS in the men. Content analysis was used to assess the qualitative interview data collected. RESULTS Three categories emerged: (1) gaining control, (2) maintaining a social life, and (3) being influenced by concurrent diseases. Less syncope/falls and remote pacemaker monitoring increased a sense of control in everyday life, while perceived physical and/or cognitive improvements influenced social participation. The men were still affected by concurrent diseases, which continuously influenced each couple's daily life. CONCLUSION Identifying and managing concurrent bradyarrhythmia through a pacemaker implant could improve well-being for people with DLB.

Abstract
Importance Psychotic symptoms greatly increase the burden of disease for people with neurodegenerative disorders and their caregivers. Cholinesterase inhibitors (ChEIs) may be effective treatment for psychotic symptoms in these disorders. Previous trials only evaluated neuropsychiatric symptoms as a secondary and an overall outcome, potentially blurring the outcomes noted with ChEI use specifically for psychotic symptoms. Objective To quantitatively assess the use of ChEIs for treatment of individual neuropsychiatric symptoms, specifically hallucinations and delusions, in patients with Alzheimer disease (AD), Parkinson disease (PD), and dementia with Lewy bodies (DLB). Data Sources A systematic search was performed in PubMed (MEDLINE), Embase, and PsychInfo, without year restrictions. Additional eligible studies were retrieved from reference lists. The final search cutoff date was April 21, 2022. Study Selection Studies were selected if they presented the results of placebo-controlled randomized clinical trials, including at least 1 donepezil, rivastigmine, or galantamine treatment arm in patients with AD, PD, or DLB; if they applied at least 1 neuropsychiatric measure including hallucinations and/or delusions; and if a full-text version of the study was available in the English language. Study selection was performed and checked by multiple reviewers. Data Extraction and Synthesis Original research data were requested on eligible studies. A 2-stage meta-analysis was then performed, using random-effects models. Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed for extracting data and assessing the data quality and validity. Data extraction was checked by a second reviewer. Main Outcomes and Measures Primary outcomes were hallucinations and delusions; secondary outcomes included all other individual neuropsychiatric subdomains as well as the total neuropsychiatric score. Results In total, 34 eligible randomized clinical trials were selected. Individual participant data on 6649 individuals (3830 [62.6%] women; mean [SD] age, 75.0 [8.2] years) were obtained from 17 trials (AD: n = 12; PD: n = 5; individual participant data were not available for DLB). An association with ChEI treatment was shown in the AD subgroup for delusions (-0.08; 95% CI, -0.14 to -0.03; P = .006) and hallucinations (-0.09; 95% CI, -0.14 to -0.04; P = .003) and in the PD subgroup for delusions (-0.14; 95% CI, -0.26 to -0.01; P = .04) and hallucinations (-0.08, 95% CI -0.13 to -0.03; P = .01). Conclusions and Relevance The results of this individual participant data meta-analysis suggest that ChEI treatment improves psychotic symptoms in patients with AD and PD with small effect sizes.

Abstract
OBJECTIVES This narrative review describes the clinical features of apathy and depression in individuals with neurocognitive disorders (NCDs), with the goal of differentiating the two syndromes on the basis of clinical presentation, diagnostic criteria, neuropathological features, and contrasting responses to treatments. METHODS Literature was identified using PubMed, with search terms to capture medical conditions of interest; additional references were also included based on our collective experience and knowledge of the literature. RESULTS Evidence from current literature supports the distinction between the two disorders; apathy and depression occur with varying prevalence in individuals with NCDs, pose different risks of progression to dementia, and have distinct, if overlapping, neurobiological underpinnings. Although apathy is a distinct neuropsychiatric syndrome, distinguishing apathy from depression can be challenging, as both conditions may occur concurrently and share several overlapping features. Apathy is associated with unfavorable outcomes, especially those with neurodegenerative etiologies (e.g., Alzheimer's disease) and is associated with an increased burden for both patients and caregivers. Diagnosing apathy is important not only to serve as the basis for appropriate treatment, but also for the development of novel targeted interventions for this condition. Although there are currently no approved pharmacologic treatments for apathy, the research described in this review supports apathy as a distinct neuropsychiatric condition that warrants specific treatments aimed at alleviating patient disability. CONCLUSIONS Despite differences between these disorders, both apathy and depression pose significant challenges to patients, their families, and caregivers; better diagnostics are needed to develop more tailored treatment and support.

[PMID: 36273804 DOI: 10.1111/psyg.12899] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Revised: 09/22/2022] [Accepted: 10/10/2022] [Indexed: 01/05/2023]
Abstract
BACKGROUND The number of patients with dementia is increasing worldwide. Modifying risk factors may significantly reduce the prevalence and cost of dementia. The number of remaining teeth, occlusal force, denture use, and periodontal disease status are associated with the risk of developing dementia. The oral environment may be a risk factor for dementia. This study aimed to investigate the association between the oral environment and cerebral blood flow in patients with mild cognitive impairment and dementia (either Alzheimer type dementia (ATD) or dementia with Lewy bodies (DLB)). We aimed to identify differences in the oral environment according to the underlying neurodegenerative disease. METHODS The participants were 25 patients with ATD and 25 patients with DLB who visited the Department of Dementia and Geriatric Medicine, Kanagawa Dental University Hospital. Patients were diagnosed with ATD and DLB by well-trained specialists certified by the Japanese Dementia Society and categorised as Level 3 or 4 by the Functional Assessment Staging of Alzheimer Disease scale. The correlation between oral environment (number of teeth, periodontal tissue, and oral function) and cerebral blood flow in each brain area calculated by single photon emission computed tomography was examined. RESULTS The DLB group showed a significant correlation between masticatory performance and cerebral blood flow in some areas, while no such correlation was observed in the ATD group. Significant correlations were found between periodontal pocket depth and bleeding on probing and cerebral blood flow in some areas in both groups, although the correlation was considerable in the ATD group. CONCLUSIONS The results of this study suggest that the association between changes in the oral environment and cerebral blood flow may differ among patients with ATD and DLB, depending on the underlying causative disease.

Abstract
INTRODUCTION Dementia with Lewy bodies (DLB) significantly increases the economic burden on caregivers and society, but few studies have focused on the costs. This study aims to evaluate the current economic costs of DLB and its related factors. METHODS A total of 193 patients diagnosed with probable DLB were consecutively enrolled from 6 memory clinics between August 2017 to July 2021. Data were collected from August to December of 2021, patients' per capita annual economic costs related to DLB in the year preceding the interview were evaluated, and factors related to the costs were assessed using regression analysis. RESULTS Patients with DLB led to per capita annual total costs of US $21,378.3 in 2021, with direct medical costs, direct non-medical costs and indirect costs of US $3471.4, US $3946.4 and US $13,960.5, respectively, accounting for 16.2%, 18.5% and 65.3%, of total costs. Factors related to the costs of DLB showed that impairments in activities of daily living (ADL) and caregivers' subjective burden had a greater impact on the total, direct medical and indirect costs. CONCLUSION The economic burden of DLB in China is huge, and indirect costs account for the largest proportion, serious impairment of the ADL and the subjective burden of caregivers, which possibly has a greater effect on costs. The substantial contributions made by family members and other unpaid caregivers of DLB should be fully recognized in strategic policy discussions and in case-level planning and assessments.

Treatment needs of dementia with Lewy bodies according to patients, caregivers, and physicians: a cross-sectional, observational, questionnaire-based study in Japan. Alzheimers Res Ther 2022; 14:188. [PMID: 36522749 PMCID: PMC9751509 DOI: 10.1186/s13195-022-01130-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Accepted: 11/23/2022] [Indexed: 12/23/2022]
Abstract
BACKGROUND Understanding the treatment needs of patients with dementia with Lewy bodies (DLB) is essential to develop treatment strategies. We examined the treatment needs of patients with DLB and their caregivers and the extent to which the attending physicians understand these treatment needs. METHODS This was a cross-sectional, observational study conducted using questionnaires for patients, caregivers, and physicians. The study participants included patients, their caregivers, and their attending physicians who were experts in DLB. Fifty-two symptoms that are frequent and clinically important in DLB were pre-selected and classified into seven symptom domains. Treatment needs of patients and caregivers were defined as "symptom that causes them most distress," and the frequency of each answer was tabulated. To assess the physician's understanding of the treatment needs of patients and caregivers, patient-physician and caregiver-physician concordance rates for each answer regarding treatment needs were calculated according to symptom domains. RESULTS In total, 263 pairs of patients-caregivers and 38 physicians were surveyed. The mean age of patients was 79.3 years, and their mean total score on the Mini-Mental State Examination was 20.9. Thirty-five and 38 symptoms were selected as symptoms causing patients and caregivers most distress, respectively. Memory impairment was most frequently selected for the treatment needs of patients, followed by constipation and bradykinesia. Memory impairment was also most frequently selected by caregivers, followed by visual hallucinations. For the symptom domain that causes patients or caregivers most distress, only about half of the patient-physician pairs (46.9%) and caregiver-physician pairs (50.8%) were matched. Logistic regression analysis identified that concordance rates for treatment needs between patient-physician and caregiver-physician were lower when autonomic dysfunction and sleep-related disorders were selected as the symptom domains that cause most distress. CONCLUSION There was considerable variability in the treatment needs of patients with DLB and their caregivers. Attending physicians had difficulty understanding the top treatment needs of their patients and caregivers, despite their expertise in DLB, because of various clinical manifestations. Attending physicians should pay more attention to autonomic dysfunction and sleep-related disorders in the treatment of DLB. TRIAL REGISTRATION UMIN Clinical Trials Registry, UMIN000041844.

Abstract
Aim This study aims to classify, describe, and compare the problems reported by care partners of adults with Alzheimer’s disease (AD) and Lewy body dementia (LBD) using the International Classification of Functioning Disability and Health (ICF) Methods Problems that care partners experience were collected during a problem-solving training intervention. The meaningful concepts were then extracted and linked to the ICF using a standardized linking technique. Results 402 meaningful concepts were extracted from 128 problems reported by care partners. 79.4% of the concepts were linkable to the ICF. “Body functions” was most frequently addressed followed by “Activities and participation.” LBD care partners reported more problems (M = 23.6 ± 13.4) on average than AD care partners (M = 19.4 ± 12.1). LBD care partners reported greater relative proportions of problems in mental function (emotional and sleep functions) than AD care partners. Conclusion This study suggests that the experience of LBD care partners may include significantly more challenges and may be more emotionally demanding than the care experience of AD care partners. Interventions designed to support care partners of adults with dementia may need to be tailored to meet the needs of care partners based on the care receiver’s type of dementia.

Abstract
Lewy body disease (LBD) is a devastating condition with cognitive and physical deficits that pose a challenge to family caregivers. The purpose of this study was to identify the needs and concerns of family caregivers of persons with LBD. A convenience sample of LBD caregivers were interviewed regarding their caregiving needs, concerns, strategies, and advice. A content analysis approach was used to organize data into themes from an existing needs and concerns framework. Findings included the need for more information about the disease, strategies for managing LBD-related emotions and behaviors, support and assistance with physical and instrumental care, and strategies for managing one's own personal responses to caregiving. Findings highlight the need for a Lewy body specific caregiver assessment tool and future caregiver interventions.

Abstract
BACKGROUND Patient-centered care requires understanding patient preferences and needs, but research on the clinical care preferences of individuals living with dementia and caregivers is sparse, particularly in dementia with Lewy bodies (DLB). METHODS Investigators conducted telephone interviews with individuals living with DLB and caregivers from a Lewy body dementia specialty center. Interviews employed a semistructured questionnaire querying helpful aspects of care and unmet needs. Investigators used a qualitative descriptive approach to analyze transcripts and identify themes. RESULTS Twenty individuals with DLB and 25 caregivers participated. Twenty-three of the caregivers were spouses, 2 were daughters. Aspects of clinical care valued by individuals with DLB and caregivers included clinician time, diagnosis, education, symptom management, communication, and caring staff. Unmet needs or challenges included patient/caregiver education, education of nonspecialist clinicians and community care providers, scheduling difficulties, caregiver support, financial concerns, assistance with advance care planning and finding local resources, and effective treatments for DLB symptoms. CONCLUSION AND RELEVANCE Improving care for individuals with DLB and their families will require a multipronged strategy including education for nonspecialist care providers, increasing specialty care access, improved clinical care services, research to support disease prognosis and treatment decisions, and local and national strategies for enhanced caregiver support.

Abstract
BACKGROUND Dementia with Lewy bodies (DLB) is characterized by neuropsychiatric symptoms, which can be distressing to caregivers. However, little is known about their subjective distress in terms of caregiver self-efficacy. Thus, we examined the differences in caregiver self-efficacy and their associated factors between DLB and Alzheimer's disease (AD) caregivers. METHODS We conducted a comprehensive questionnaire for DLB and AD caregivers. Caregiver self-efficacy was evaluated using three domains (Self-Efficacy for Obtaining Respite: SE-OR, Self-Efficacy for Responding to Disruptive Patient Behaviours: SE-RDPB, Self-Efficacy for Controlling Upsetting Thoughts about Caregiving: SE-CUT) of the Revised Scale for Caregiving Self-Efficacy (RSCSE). In addition, data on the following features of caregivers were assessed: depression, sleep disturbance, caregiver burden, executive function, loneliness, social support, and distress associated with neuropsychiatric symptoms. The patients were assessed for general cognitive tasks, executive function, and neuropsychiatric symptoms. RESULTS Compared with AD caregivers, DLB caregivers experienced a significantly higher burden in terms of not only various clinical factors, but also all three domains of caregiver self-efficacy. Among the caregiver-associated factors, different domains were predictors of self-efficacy in DLB and AD caregivers (distress due to sleep disturbances in DLB patients; distress due to delusions in AD patients). Among the patient-associated factors, different domains were also predictors of self-efficacy in DLB and AD caregivers (sleep disturbances in DLB patients; delusions in AD patients). Among both the caregivers and the patients, executive function was a significant predictor of one RSCSE domain (SE-CUT). CONCLUSIONS A reduction in caregiver self-efficacy may contribute to a severe subjective burden among DLB caregivers. Furthermore, two neuropsychiatric symptoms (delusions and sleep disturbances) affected caregiver self-efficacy differently depending on whether care was being provided to a DLB or AD patient. Understanding the association between specific neuropsychiatric symptoms and caregiver self-efficacy may be useful for conducting interventions for DLB patients.

Abstract
BACKGROUND Pre-loss grief increases as dementia advances. Caregivers who experience pre-loss grief face risks to their own physical and psychological health. OBJECTIVE The study examined factors associated with pre-loss grief in caregivers of older adults with dementia with Lewy bodies (DLB) to determine whether overall caregiver experiences differ based on the stages of DLB in care recipients. The study also compared pre-loss grief in caregivers of DLB patients with that in caregivers of patients with Alzheimer's disease (AD) and other dementias. METHOD Using a cross-sectional design, 714 caregivers of older adults with dementia (488 DLB, 81 AD, 145 other dementias) completed an online survey on pre-loss grief. Multivariate linear regression identified risk factors associated with pre-loss grief and analysis of variance examined whether pre-loss grief in caregivers differed significantly based on type of dementia or stage of DLB. RESULTS Being the caregiver of a spouse, lower level of caregiver well-being, lower psychological well-being of the caregiver, and higher level of burden were associated (p < 0.005) with increased pre-loss grief in caregivers of older adults with DLB. There was no significant difference in caregiver burden, well-being, or depression according to the various stages of DLB (mild, moderate, severe, deceased) in the care recipients. There was no significant difference in pre-loss grief in caregivers of DLB care recipients compared to caregivers of patients with other dementias. CONCLUSION Assessment of DLB caregivers and appropriate interventions should be conducted to reduce their burden and emotional distress to decrease the incidence of pre-loss grief.

Abstract
Individuals with dementia with Lewy bodies (DLB) commonly die from dementia-related causes, but little is known regarding caregiver experiences during the end-of-life period in DLB. This reflects a critical knowledge gap given the high frequency of informal caregiving for individuals with dementia, high caregiver burden in DLB, and the fact that most individuals with DLB die from this disease. Investigators conducted telephone interviews with family members of individuals who died with DLB in the last 5 years. Investigators used a qualitative descriptive approach to analyze interview transcripts. Participants included 15 children, 13 spouses, and 2 other family members. Interviews averaged 31 min. Major themes included caregivers as the main drivers of care for individuals with DLB throughout the disease course and at the end of life, the impact of DLB features (e.g., fluctuations, hallucinations, and delusions) on end-of-life experiences, experiences relating to the caregiving role, death and post-death experiences, and supports employed by caregivers in the end-of-life period. End-of-life experiences for caregivers of individuals with DLB built on the accumulated burden of the disease course, where caregivers were often responsible for driving DLB care-from making the diagnosis to educating healthcare professionals and double-checking medical decisions. While some end-of-life experiences were consistent with those described in dementia palliative care more generally (e.g., financial stresses, poor sleep, being overwhelmed, and needing increased education and support), many DLB features specifically affected end-of-life caregiver experiences, such as the presence of delusions. Improving caregiver experiences at the end of life in DLB will require improved diagnosis and care for individuals with DLB throughout the disease course and also better strategies for treating behavioral symptoms. More research is needed regarding drivers of quality end-of-life experiences for individuals with DLB and their families and how drivers and strategies may differ between dementias.

Abstract
BACKGROUND AND OBJECTIVES Persons with dementia experience behavioral symptoms, such as agitation and repeating questions, which have been reported as one of the most burdensome and stressful aspects of providing care for dementia caregivers. However, no published studies have assessed the subjective experience of behavioral symptoms and distress from people with dementia. RESEARCH DESIGN AND METHODS The current pilot study examined the feasibility of people with dementia providing self-reported behaviors and behavioral-related distress. Data from a larger, on-going research study was used consisting of people with mild to moderate dementia (n = 12) residing in a long-term memory care facility. RESULTS Participants were able to provide reliable (∝=.91) self-reported data concerning their own behaviors and behavioral-related distress with variability among responses. The most frequently self-reported behaviors included agitation (66.7%) and complaining/criticizing things (58.3%) while the least reported behaviors were refusing to be left alone (8.3%) and yelling/swearing (8.3%). The highest behavioral distress reported was agitation (58.3%) while the least was wandering (8.3%). DISCUSSION AND IMPLICATIONS Understanding the subjective, perceived experience of people with dementia provides valuable information on the illness experience. Additional research is needed to examine the role and impact of self-reported behaviors and the resulting behavioral- related distress on outcomes of well-being. Subjective reports of behavioral-related distress could predict well-being, above and beyond that of traditional objective measures, creating the potential for novel non-pharmacological intervention development for people with dementia.

Abstract
BACKGROUND The DEmEntia with LEwy bOdies Project (DEvELOP) aims to phenotype patients with dementia with Lewy bodies (DLB) and study the symptoms and biomarkers over time. Here, we describe the design and baseline results of DEvELOP. We investigated the associations between core and suggestive DLB symptoms and different aspects of disease burden, i.e., instrumental activities of daily living (IADL) functioning, quality of life (QoL), and caregiver burden. METHODS We included 100 DLB patients (69 ± 6 years, 10%F, MMSE 25 ± 3) in the prospective DEvELOP cohort. Patients underwent extensive assessment including MRI, EEG/MEG, 123FP-CIT SPECT, and CSF and blood collection, with annual follow-up. Core (hallucinations, parkinsonism, fluctuations, RBD) and suggestive (autonomous dysfunction, neuropsychiatric symptoms) symptoms were assessed using standardized questionnaires. We used multivariate regression analyses, adjusted for age, sex, and MMSE, to evaluate how symptoms related to the Functional Activities Questionnaire, QoL-AD questionnaire, and Zarit Caregiver Burden Interview. RESULTS In our cohort, RBD was the most frequently reported core feature (75%), while visual hallucinations were least frequently reported (39%) and caused minimal distress. Suggestive clinical features were commonly present, of which orthostatic hypotension was most frequently reported (64%). Ninety-five percent of patients showed EEG/MEG abnormalities, 88% of 123FP-CIT SPECT scans were abnormal, and 53% had a CSF Alzheimer's disease profile. Presence of fluctuations, lower MMSE, parkinsonism, and apathy were associated with higher IADL dependency. Depression, constipation, and lower IADL were associated with lower QoL-AD. Apathy and higher IADL dependency predisposed for higher caregiver burden. CONCLUSION Baseline data of our prospective DLB cohort show clinically relevant associations between symptomatology and disease burden. Cognitive and motor symptoms are related to IADL functioning, while negative neuropsychiatric symptoms and functional dependency are important determinants of QoL and caregiver burden. Follow-up is currently ongoing to address specific gaps in DLB research.

Abstract
BACKGROUND Caregivers of persons living with Alzheimer's disease (AD), dementia with Lewy bodies (DLB), and Parkinson's disease dementia (PDD) are faced with numerous challenges. However, little is known about the caregiving experience across different dementias. OBJECTIVE The aims of this cross-sectional study were to examine the differences in the caregiver experience between DLB, PDD, and AD. METHODS Respondents were caregivers (N = 515; 384 DLB, 69 AD, 62 PDD) who completed a 230-question survey including sociodemographics, disease severity, neuropsychiatric symptoms, and measures of grief, burden, depression, quality of life, social support, well-being, care confidence, and mastery/self-efficacy. RESULTS There were no differences in caregiver age, sex, race, or education, or in the distribution of disease severity between diagnostic groups. Constructs were highly intercorrelated with positive attributes (caregiver QoL, care recipient QoL, social support, well-being, mastery and care confidence) being inversely correlated with negative attributes (burden, grief, and depression). Across dementia etiologies, no differences were reported for quality of life, social support, depression, well-being, psychological well-being, mastery, care confidence, burden or grief. Instead, we found that the caregiver's experience was dependent on caregiver characteristics, person living with dementia characteristics and their most disturbing symptom, with behavior, personality changes, and sleep having the greatest effect on constructs. CONCLUSION Caregiver ratings of psychosocial constructs may be more dependent on care recipient-caregiver dyad characteristics and the current symptoms than the underlying cause of those symptoms. Interventions to improve the caregiving experience should be developed to address specific psychosocial constructs rather than focusing on disease etiology or stage.

Abstract
BACKGROUND Funding bodies are placing increased emphasis on patient and public involvement in research, but the research priorities of individuals and caregivers living with dementia with Lewy bodies (DLB) are unknown. METHOD Investigators conducted telephone interviews with individuals living with DLB and caregivers. Participants were recruited from a Lewy Body Dementia Association Research Center of Excellence. Interviews employed a semi-structured questionnaire querying research needs in different categories and then asking participants to select their top priorities. Investigators used a qualitative descriptive approach to analyze transcripts and identify themes. RESULTS Twenty individuals with DLB and 25 caregivers participated. Seventeen from each group participated as part of a patient-caregiver dyad. Twenty-three of the caregivers were spouses, two were daughters. Individuals with DLB and caregivers identified research needs relating to focusing on awareness, determining the cause of DLB, improving diagnosis, and investigating what to expect/disease stages. Participants also highlighted DLB symptoms needing additional research, therapies to prevent, cure, or slow the progression of DLB, and research targeting daily function and quality of life, caregiving, and improving education. CONCLUSIONS These findings support the research priorities defined in the National Institutes of Health dementia care summits in addition to ADRD priority-setting summits. Research is needed across all domains of DLB. Funding should be informed by the priorities of all relevant stakeholders and support research investigating causes, natural history, biomarkers, and treatment in addition to research targeting themes regarding living with disease (e.g. independence, quality of life, caregiving, and education).

Abstract
More than half of the patients with Alzheimer's disease (AD) have comorbidities including TDP-43 and Lewy bodies, which are also associated with frontotemporal lobar degeneration and dementia with Lewy bodies, respectively. These comorbidities may help explain the overlapping neuropsychiatric symptoms between AD and other dementias. Data on 221 AD patients with Neuropsychiatric Inventory-Questionnaire were obtained from the National Alzheimer's Coordinating Center. TDP-43 was associated with aberrant motor activity, whereas Lewy bodies were associated with anxiety, irritability, sleep behavior, and appetite problems. The associations between these comorbidities and neuropsychiatric symptoms were more significant for patients with sparse diffuse plaques.

Abstract
Dementia with Lewy bodies (DLB) is the second most common neurodegenerative cause of dementia, behind Alzheimer's disease (AD). It is now established that cerebral inflammation has a key role in the aetiology and progression of AD, but this has yet to be confirmed in DLB. We aimed to determine the neuroinflammatory profile in the cerebral cortex of a large cohort of DLB cases. Thirty post-mortem confirmed DLB cases and twenty-nine matched controls were immunolabelled (Brodmann area 21) and quantified for: neuropathology-αSYN, Aβ, P-tau; microglial phenotype-Iba1, HLA-DR, CD68, FcƴR (CD64, CD32a, CD32b, CD16); presence of T lymphocytes-CD3; and anti-inflammatory markers-IL4R, CHI3L1. Status spongiosis, as a marker of neuropil degeneration, was quantified using Haematoxylin and Eosin staining. We found no significant difference between groups in protein load for Iba1, HLA-DR, CD68, CD64, CD32b, IL4R, or CHI3L1, despite increased neuropathology in DLB. CD32a load was significantly lower, and CD16 load higher, in DLB compared with controls. There was no difference in status spongiosis between groups. Significantly more DLB cases than controls showed T-lymphocyte recruitment. Overall, we conclude that microglial activation is not a prominent feature of DLB, and that this may be associated with the relatively modest neuropil degeneration observed in DLB. Our findings, based on the largest post-mortem cohort to date exploring neuroinflammation in DLB, demonstrate a dissociation between protein deposition, neurodegeneration and microglial activation. The relative preservation of cortical structures in DLB suggests the dementia could be more amenable to potential therapies.

Abstract
BACKGROUND Lewy body dementia, consisting of both dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD), is considerably under-recognised clinically compared with its frequency in autopsy series. AIMS This study investigated the clinical diagnostic pathways of patients with Lewy body dementia to assess if difficulties in diagnosis may be contributing to these differences. METHOD We reviewed the medical notes of 74 people with DLB and 72 with non-DLB dementia matched for age, gender and cognitive performance, together with 38 people with PDD and 35 with Parkinson's disease, matched for age and gender, from two geographically distinct UK regions. RESULTS The cases of individuals with DLB took longer to reach a final diagnosis (1.2 v. 0.6 years, P = 0.017), underwent more scans (1.7 v. 1.2, P = 0.002) and had more alternative prior diagnoses (0.8 v. 0.4, P = 0.002), than the cases of those with non-DLB dementia. Individuals diagnosed in one region of the UK had significantly more core features (2.1 v. 1.5, P = 0.007) than those in the other region, and were less likely to have dopamine transporter imaging (P < 0.001). For patients with PDD, more than 1.4 years prior to receiving a dementia diagnosis: 46% (12 of 26) had documented impaired activities of daily living because of cognitive impairment, 57% (16 of 28) had cognitive impairment in multiple domains, with 38% (6 of 16) having both, and 39% (9 of 23) already receiving anti-dementia drugs. CONCLUSIONS Our results show the pathway to diagnosis of DLB is longer and more complex than for non-DLB dementia. There were also marked differences between regions in the thresholds clinicians adopt for diagnosing DLB and also in the use of dopamine transporter imaging. For PDD, a diagnosis of dementia was delayed well beyond symptom onset and even treatment.

Abstract
BACKGROUND Dementia with Lewy bodies (DLB) is the second most common form of dementia. Current symptomatic treatment with medications remains inadequate. Deep brain stimulation of the nucleus basalis of Meynert (NBM DBS) has been proposed as a potential new treatment option in dementias. OBJECTIVE To assess the safety and tolerability of low frequency (20 Hz) NBM DBS in DLB patients and explore its potential effects on both clinical symptoms and functional connectivity in underlying cognitive networks. METHODS We conducted an exploratory randomised, double-blind, crossover trial of NBM DBS in six DLB patients recruited from two UK neuroscience centres. Patients were aged between 50 and 80 years, had mild-moderate dementia symptoms and were living with a carer-informant. Patients underwent image guided stereotactic implantation of bilateral DBS electrodes with the deepest contacts positioned in the Ch4i subsector of NBM. Patients were subsequently assigned to receive either active or sham stimulation for six weeks, followed by a two week washout period, then the opposite condition for six weeks. Safety and tolerability of both the surgery and stimulation were systematically evaluated throughout. Exploratory outcomes included the difference in scores on standardised measurements of cognitive, psychiatric and motor symptoms between the active and sham stimulation conditions, as well as differences in functional connectivity in discrete cognitive networks on resting state fMRI. RESULTS Surgery and stimulation were well tolerated by all six patients (five male, mean age 71.33 years). One serious adverse event occurred: one patient developed antibiotic-associated colitis, prolonging his hospital stay by two weeks. No consistent improvements were observed in exploratory clinical outcome measures, but the severity of neuropsychiatric symptoms reduced with NBM DBS in 3/5 patients. Active stimulation was associated with functional connectivity changes in both the default mode network and the frontoparietal network. CONCLUSION Low frequency NBM DBS can be safely conducted in DLB patients. This should encourage further exploration of the possible effects of stimulation on neuropsychiatric symptoms and corresponding changes in functional connectivity in cognitive networks. TRIAL REGISTRATION NUMBER NCT02263937.

Reduced Awareness of Memory Deficit is Associated With Increased Medicare Home Health Care Use in Dementia. Alzheimer Dis Assoc Disord 2020; 33:62-67.

Abstract
OBJECTIVE The objective of this study was to examine whether reduced awareness of memory deficits in individuals with dementia is associated with more frequent need for Medicare home health care services. METHODS Cross-sectional analyses were conducted in a multicenter, clinic-based cohort. In total, 192 participants diagnosed with dementia and their informants were independently asked whether or not the participant demonstrated cognitive symptoms of dementia related to memory and word-finding. Participant self-awareness was measured as the discrepancy between participant and caregiver report of these symptoms. Annual Medicare home health benefit use data was obtained from Medicare claims matched by year to the Predictors study visit. RESULTS Participants that used home health services had lower awareness scores than those who did not. Awareness remained independently associated with home health use in a logistic regression adjusted for age, gender, education, caregiver relationship, global cognition, dementia subtype, and medical comorbidities. IMPLICATIONS Reduced self-awareness of memory deficits in individuals with dementia is associated with more frequent use of Medicare home health services. The disproportionate use of in-home assistance as a function of awareness level may reflect dangers faced by patients, and challenges faced by caregivers, when patients have limited awareness of their memory deficits. Current results have implications for clinical care, caregiver education, and models of health care utilization.

Abstract
Objective The objective of this study was to examine clinical characteristics, cognitive decline, and predictors for time to dementia in prodromal dementia with Lewy bodies with mild cognitive impairment (MCI‐LB) compared with prodromal Alzheimer's disease (MCI‐AD). Methods We included 73 MCI‐LB patients (12% female; 68 ± 6 years; Mini Mental State Examination, 27 ± 2) and 124 MCI‐AD patients (48% female; 68 ± 7 years; Mini Mental State Examination, 27 ± 2) from the Amsterdam Dementia Cohort. Follow‐up was available for 61 MCI‐LB patients and all MCI‐AD patients (3 ± 2 years). We evaluated dementia with Lewy bodies core features, neuropsychiatric symptoms, caregiver burden (Zarit caregiver burden interview), MRI, apolipoprotein genotype, and cerebrospinal fluid biomarkers (tau/Aβ1–42 ratio). Longitudinal outcome measures included cognitive slopes (memory, attention, executive functions, and language and visuospatial functions) and time to dementia. Results Parkinsonism was the most frequently present core feature in MCI‐LB (69%). MCI‐LB patients more often had neuropsychiatric symptoms and scored higher on ZARIT when compared with the MCI‐AD patients. Linear mixed models showed that at baseline, MCI‐LB patients performed worse on nonmemory cognitive domains, whereas memory performance was worse in MCI‐AD patients. Over time, MCI‐LB patients declined faster on attention, whereas MCI‐AD patients declined faster on the Mini Mental State Examination and memory. Cox proportional hazards regressions showed that in the MCI‐LB patients, lower attention (hazard ratio [HR] = 1.6; 95% confidence interval [CI], 1.1–2.3) and more posterior cortical atrophy (HR = 3.0; 95% CI, 1.5–5.8) predicted shorter time to dementia. In the MCI‐AD patients, worse performance on memory (HR = 1.1; 95% CI, 1.0–1.2) and executive functions (HR = 1.3; 95% CI, 1.0–1.6) were independently associated with time to Alzheimer's dementia. Conclusion MCI‐LB patients have distinct neuropsychiatric and cognitive profiles with prominent decline in attention when compared with MCI‐AD patients. Our results highlight the importance of early diagnosis because symptoms already have an impact in the prodromal stages. © 2020 The Authors.

Abstract
OBJECTIVES To explore and compare levels of mental health, care burden, and relationship satisfaction among caregiving spouses of people with mild cognitive impairment or dementia in Parkinson disease (PD-MCI or PDD) or dementia with Lewy bodies (DLB). METHODS Spouses (n = 136) completed measures of mood, stress, resilience, general health, quality of life, care burden, and relationship satisfaction, as well as sociodemographic factors. Additionally, data on motor and neuropsychiatric symptom severity of people with PD-MCI, PDD, or DLB were obtained in a subsample. RESULTS Most spouses were married women (>85%) who provided a median of 4 years of care and 84 hours of weekly care. Among these, relationship dissatisfaction, stress, anxiety, care burden, and feelings of resentment were common. Spouses of people with PDD and DLB had significantly higher rates of burden, resentment, and depression compared to spouses of people with PD-MCI. Furthermore, unique group differences emerged whereby spouses of people with PDD had significantly longer duration of care provision, higher stress, more relationship dissatisfaction, and fewer positive interactions, compared to PD-MCI group, whereas anxiety and lower levels of mental health were prominent in spouses of people with DLB, compared to PD-MCI group. Despite this, the majority of spouses reported good quality of life, resilience, and satisfaction with the caring role. CONCLUSION Both PDD and DLB significantly contribute to poorer mental health and higher levels of care burden in spouses. Clinicians should actively screen the risk of burden, stress, depression, and anxiety among caregiving spouses of people with these conditions.

[PMID: 29023987 DOI: 10.1002/gps.4812] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2017] [Accepted: 08/23/2017] [Indexed: 11/12/2022]
Abstract
INTRODUCTION Neuropsychiatric symptoms (NPS) are common at all stages of Alzheimer disease (AD). Delusions in AD are associated with negative clinical consequences and may signal rapid disease progression. Hence, we sought to determine the prevalence of delusions in drug-naïve (no cholinesterase inhibitor or neuroleptic medications) AD patients. METHODS In this meta-analysis, a search of the EMBASE, MEDLINE, and PsycINFO databases was performed. We selected studies reporting delusion prevalence measured by the Neuropsychiatric Inventory (NPI) in drug-naïve AD patients. An aggregate delusion event rate with 95% confidence interval (CI) was calculated. The I2 statistic was used to assess the magnitude of between-study heterogeneity. Single variable meta-regressions allowed examination of the effect of moderating factors and heterogeneity. Quantitative measures were used to appraise for publication bias. RESULTS We identified 6 studies with 591 participants allowing calculation of the aggregate delusional prevalence rate. Irrespective of dementia severity, the aggregate event rate for delusions was 29.1% (95% CI: 20-41%; I2 = 84.59). No publication bias was observed. CONCLUSION This meta-analysis calculates a 29.1% prevalence rate of delusions in AD patients. There is a trend towards increasing delusion prevalence in concordance with increasing severity of dementia. Given delusions are associated with poorer outcomes, the obtained prevalence should motivate clinicians to screen carefully for delusions. Current literature limitations warrant future studies, with sub-analyses on dementia severity, and other neurobiological factors known to influence the presence of delusions.

Abstract
BACKGROUND AND OBJECTIVES Dementia caregiving has been associated with increased burden, depression, grief, a decreased sense of well-being and quality of life, and a weakening of social support. Little is known about the experience of caregiving in Dementia with Lewy Bodies (DLB). The present study examines differences in the caregiving experience of spouse versus adult child caregivers of individuals with DLB. RESEARCH DESIGN AND METHODS In this cross-sectional analytic study of spouses (n = 255) and adult children (n = 160) caregivers of individuals with DLB, participants completed an online survey of burden, grief, depression, well-being, quality of life, and social support. RESULTS Adult child caregivers were more likely to care for women (p < .001) and see the care recipient less often (p < .001) than spouses. Adult child caregivers reported lower quality of life (p < .001) and more caregiver burden (p < .009), but also greater social support (p < .001) than spouses. Between group analyses of caregiver type by disease severity demonstrated that spousal caregivers experience greater grief with advancing disease (p = .005), while adult child caregivers increase social support with advancing disease (p < .001). DISCUSSION AND IMPLICATIONS Spouses and adult children experience DLB caregiving differently. This was explained by the younger age of the adult child caregiver, frequency of contact with the care recipient, and differences in the care recipient's characteristics, frequency of neuropsychiatric symptoms, and disease severity. DLB caregiver support for this population should target psychoeducation for complicated neuropsychiatric symptoms in the care recipient. Screening all DLB caregivers for burden, grief, and depression is suggested to identify those that may benefit most from intervention. Spouses specifically may benefit from interventions that target increasing social support, while adult child caregivers may benefit from interventions aimed at mitigating burden and improving quality of life.

Abstract
OBJECTIVE To explore the subjective experience of living with dementia with Lewy bodies (DLB). DESIGN A qualitative study of in-depth interviews using interpretative phenomenological analysis. SETTING A memory clinic in Malmö, southern Sweden. PARTICIPANTS A purposive sample of five male participants with DLB between the ages of 78 and 88 years and disease duration of 1.5-7 years. RESULTS Three themes were identified in relation to the participants' experiences of living with DLB: (1) disease impact, in terms of symptom experience and restricted participation and activities; (2) self-perception and coping strategies; (3) importance of others, such as healthcare, family and friends. CONCLUSIONS This study provides a broad insight into the first-hand experience of living with DLB and how it compares with other dementia types. Findings highlight factors characterising the disease experience and well-being, and how persons with DLB address challenges arising secondary to disease. These findings are important for both research and clinical practice, demonstrating the feasibility of direct involvement of DLB persons in identifying important aspects of care, which include improved healthcare services.

Consecutive sessions of transcranial direct current stimulation do not remediate visual hallucinations in Lewy body dementia: a randomised controlled trial. Alzheimers Res Ther 2019; 11:9.

Abstract
BACKGROUND Complex visual hallucinations are common in Lewy body dementia (LBD) and can cause significant patient and caregiver distress. Current treatments are primarily pharmacological in nature and have limited efficacy and associated side effects. The objective of this study was to assess the effects of consecutive sessions of transcranial direct current stimulation (tDCS) on visual hallucination frequency and severity in LBD, at short-term and long-term follow-up stages. METHODS The study was a randomised, double-blind, placebo-controlled trial involving 40 participants with LBD (Mage = 75.52 years, SDage = 8.69 years) which was conducted at a single site between November 2013 and December 2017. Participants received two consecutive 20-min sessions of active (0.048 mA/cm2) or placebo tDCS, separated by a 30-min break, over 5 consecutive days. The anodal electrode was applied to the right parietal cortex (P4) and the cathodal electrode was applied to the occipital cortex (Oz). The primary outcome measure was the Neuropsychiatric Inventory (NPI) hallucinations subscale, as completed by a caregiver/informant at baseline and day 5 (short-term) follow-up, and month 1 and month 3 (long-term) follow-up. Secondary outcome measures included visual cortical excitability, as measured using transcranial magnetic stimulation, computerised attentional and visuoperceptual tasks, and measures of global cognition and cognitive fluctuations. RESULTS Complete study data were obtained from 36 participants. There was an overall improvement in visual hallucinations (NPI) for both groups at day 5 relative to baseline, with a medium-to-large effect size; however, compared to placebo, active tDCS did not result in any improvements in visual hallucinations (NPI) at day 5 relative to baseline, or at month 1 or month 3 follow-up time points. Additionally, comparisons of secondary outcome measures showed that active tDCS did not result in any improvements on any measure (visual cortical excitability, attentional and visuoperceptual tasks or cognitive measures) at any time point. CONCLUSIONS Repeated consecutive sessions of parietal anodal tDCS, and occipital cathodal tDCS, do not improve visual hallucinations or visuoperceptual function, or alter visual cortical excitability in LBD.

Abstract
BACKGROUND AND PURPOSE Complex, well-formed, and detailed visual hallucinations (VHs) are among the core clinical features of dementia with Lewy bodies (DLB). We investigated the diagnostic value of VHs in different types of very mild degenerative dementia. METHODS Participants were required to complete a structured interview form recording their basic data, clinical history, neuropsychological tests, and neuropsychiatric symptoms. Basic demographic characteristics of the participants were summarized and compared. The frequency and association factors of VHs were compared among three major degenerative dementia groups, namely, Alzheimer's disease (AD), Parkinson's disease dementia (PDD), and DLB. RESULTS A total of 197 patients with dementia and a clinical dementia rating of 0.5 were investigated, comprising 124 with AD, 35 with PDD, and 38 with DLB. A significantly higher frequency of VHs was found in the DLB group compared with the other groups (DLB, PDD, and AD = 31.6%, 11.4%, and 4.0%; p < 0.001). A multivariable logistic regression test for associations of positive VHs revealed that DLB was the only independently predictive factor (odds ratio: 13.62; p < 0.001). CONCLUSION Our findings revealed a high diagnostic value of VHs in very mild degenerative dementia. VHs in this stage of dementia were significantly associated with DLB, and more than 30% of patients with very mild dementia caused by DLB presented with VHs.

Abstract
Dementia with Lewy bodies (DLB) is the second most common neurodegenerative dementia following Alzheimer disease. It stems from the formation of Lewy bodies, which contain aggregates of the misfolded protein, α-synuclein. These deposit in areas of the nervous system and brain, leading to neuronal cell death and causing clinically apparent symptoms. Because of its clinical overlap with other forms of dementia, DLB is often underdiagnosed and misdiagnosed. There is currently no cure for DLB and treatments are aimed at ameliorating specific symptoms.

Abstract
UNLABELLED ABSTRACTBackground:Very few recent studies are available that compare caregiver burden, sleep quality, and stress in caregivers of different types of dementia. We aimed to investigate caregiver burden, sleep quality, and stress in caregivers of patients with frontotemporal lobar degeneration and dementia with Lewy bodies, as compared with caregivers of patients with Alzheimer's disease. METHODS This study was carried out from March 2011 to January 2014. In total, 492 dyads of patient and caregiver (frontotemporal lobar degeneration, n = 131; dementia with Lewy bodies, n = 36; Alzheimer's disease, n = 325) participated in this study. We compared patients with respect to the Neuropsychiatric Inventory and caregivers with respect to the Zarit Caregiver Burden Interview, Pittsburgh Sleep Quality Index, Patient Health Questionnaire-9, and Generalized Anxiety Disorder scale. RESULTS Frontotemporal lobar degeneration and dementia with Lewy bodies patients presented significantly more neuropsychiatric symptoms compared to Alzheimer's disease patients. Caregivers of frontotemporal lobar degeneration and dementia with Lewy bodies patients experienced significantly more burden compared to Alzheimer's disease caregivers. Furthermore, among caregivers of both frontotemporal lobar degeneration and dementia with Lewy bodies patients burden was predicted by the neuropsychiatric symptoms, PHQ-9 scores, and GAD-7 scores. CONCLUSIONS The frequency and severity of behavioral disturbances in patient and caregiver stress accounted for the increased caregiver burden, which suggests that frontotemporal lobar degeneration and dementia with Lewy bodies caregivers should receive more support than is currently available.

Abstract
OBJECTIVE To study the level of carer reported distress in mild dementia, over a 3-year period. METHODS This study is part of the Norwegian DemVest-study and utilises data from carers of people with mild dementia (n = 223). Those diagnosed with dementia with Lewy bodies (DLB, n = 63) and Alzheimer's disease (AD, n = 97) were included together with other dementia types (n = 63). The Relatives' Stress Scale was used to assess the level of reported distress in carers. Descriptive and a linear mixed effects models including diagnosis, time, and the interaction between time and diagnosis were performed. RESULTS Carer distress in mild dementia increased significantly over time (P = 0.011), particularly from baseline until 2 (P = 0.001) years follow-up. Carer distress in people caring for those with AD increased significantly, from baseline until 2 (P = 0.047) and 3 (P = 0.019) years follow-up. Distress in carers of people with DLB was high at baseline and remained relatively stable across the 3-year period. However, admission to a nursing home during the first year of follow-up was associated with a significantly lower reported carer distress in those caring for a person with DLB (P = 0.002), compared with those caring for a person with DLB living at home. CONCLUSION Being a carer to a person with mild dementia is associated with increasing distress. However, the burden of distress changes with the diagnosis, time, and situation, which highlights the dynamic nature of the caring role. Findings have important implications for health services for people diagnosed with mild dementia and their carers.

Abstract
BACKGROUND AND PURPOSE Apathy is an important neuropsychiatric feature of Parkinson's disease (PD), which often emerges before the onset of motor symptoms. Patients with rapid eye movement sleep behaviour disorder (RBD) have a high probability of developing PD in future. Neuropsychiatric problems are common in RBD, but apathy has not previously been detailed in this key prodromal population. METHODS Eighty-eight patients with polysomnographically proven RBD, 65 patients with PD and 33 controls were assessed for apathy using the Lille Apathy Rating Scale. Cognition and depression were also quantified. The sensitivity of the Unified Parkinson's Disease Rating Scale screening questions for apathy and depression was calculated. RESULTS A total of 46% of patients with RBD were apathetic, compared with 31% of patients with PD in our sample. Most patients with RBD with depression were apathetic but more than half of apathetic patients were not depressed. The sensitivity of the single Unified Parkinson's Disease Rating Scale screening question was only 33% for mild apathy and 50% for severe apathy. CONCLUSIONS Apathy is common in RBD and is underestimated by a single self-report question. Recognition of apathy as a distinct neuropsychiatric feature in RBD could aid targeted treatment interventions and might contribute to the understanding of prodromal PD.

Abstract
BACKGROUND/OBJECTIVE The aim of this study was to describe the rate and clinical predictors of cognitive decline in dementia with Lewy bodies (DLB), and compare the findings with Alzheimer's disease (AD) and Parkinson's disease dementia (PDD) patients. METHODS Longitudinal scores for the Mini-Mental State Examination (MMSE) in 1,290 patients (835 DLB, 198 PDD, and 257 AD) were available from 18 centers with up to three years longitudinal data. Linear mixed effects analyses with appropriate covariates were used to model MMSE decline over time. Several subgroup analyses were performed, defined by anti-dementia medication use, baseline MMSE score, and DLB core features. RESULTS The mean annual decline in MMSE score was 2.1 points in DLB, compared to 1.6 in AD (p = 0.07 compared to DLB) and 1.8 in PDD (p = 0.19). Rates of decline were significantly higher in DLB compared to AD and PDD when baseline MMSE score was included as a covariate, and when only those DLB patients with an abnormal dopamine transporter SPECT scan were included. Decline was not predicted by sex, baseline MMSE score, or presence of specific DLB core features. CONCLUSIONS The average annual decline in MMSE score in DLB is approximately two points. Although in the overall analyses there were no differences in the rate of decline between the three neurodegenerative disorders, there were indications of a more rapid decline in DLB than in AD and PDD. Further studies are needed to understand the predictors and mechanisms of cognitive decline in DLB.

Abstract
OBJECTIVE Neuropsychiatric symptoms (NPSs) are common in dementia, and they have been identified as important care-recipient variables in terms of their impact on caregiver burden. The aim of this review was to describe how individual NPSs in dementia, assessed using the Neuropsychiatric Inventory, are associated with caregiver burden. METHODS We performed a systematic review of English language, peer-reviewed articles retrieved from MEDLINE, PSYCINFO, and EMBASE. RESULTS A total of 13 studies met the inclusion criteria. Four studies examined the association between individual NPSs and caregiver burden using the Spearman rank correlation test, while three used Pearson's correlation test. Of the remaining studies, five used multiple regression analyses and one the chi-squared test. The majority of included studies did not differentiate between dementia subtypes in the analysis or mainly included only caregivers of people with Alzheimer's disease. The Clinical Dementia Rating score and mean Mini-Mental State Examination score indicate mild to moderate dementia. The majority of caregivers were women, most of whom were children (53.8%) or spouses (36%). The data indicated that irritability, followed by agitation, sleep disturbances, anxiety, apathy, and delusion seem to impact caregiver burden the most. CONCLUSION Our principal finding is that irritability, agitation, sleep disturbances, anxiety, apathy, and delusion seem to exert the most impact on caregiver burden. Heterogeneity in the measures and statistical analyses used, however, makes it difficult to make conclusive interpretations. Future research in this field would benefit from standardization of the scientific methodology in use. Copyright © 2017 John Wiley & Sons, Ltd.

Abstract
OBJECTIVE Patients with dementia with Lewy bodies (DLB) often experience visual hallucinations, which are related to decreased quality of life for patients and increased caregiver distress. The pathologic changes that contribute to visual hallucinations are not known, but several hypotheses implicate deficient attentional processing. The superior colliculus has a role in visual attention and planning eye movements and has been directly implicated in several models of visual hallucinations. Therefore, the present study sought to identify neurodegenerative changes that may contribute to hallucinations in DLB. METHODS Postmortem superior colliculus tissue from 13 comparison, 10 DLB, and 10 Alzheimer disease (AD) cases was evaluated using quantitative neuropathologic methods. RESULTS α-Synuclein and tau deposition were more severe in deeper layers of the superior colliculus. DLB cases had neuronal density reductions in the stratum griseum intermedium, an important structure in directing attention toward visual targets. In contrast, neuronal density was reduced in all laminae of the superior colliculus in AD. CONCLUSION These findings suggest that regions involved in directing attention toward visual targets are subject to neurodegenerative changes in DLB. Considering several hypotheses of visual hallucinations implicating dysfunctional attention toward external stimuli, these findings may provide evidence of pathologic changes that contribute to the manifestation of visual hallucinations in DLB.

Abstract
BACKGROUND/AIMS Hypersomnia is common in dementia with Lewy bodies (DLB). We assessed the efficacy, safety, and tolerability of armodafinil for hypersomnia associated with DLB. METHODS We performed a 12-week pilot trial of armodafinil therapy (125-250 mg orally daily) in DLB outpatients with hypersomnia. The patients underwent neurologic examinations, a neuropsychological battery, laboratory testing, electrocardiography, and polysomnography. Efficacy was assessed at 2, 4, 8, and 12 weeks. Safety assessment included laboratory examinations, QTc interval, and heart rate. Tolerability was assessed by analysis of adverse events. Data were analyzed using the last-observation-carried-forward method. RESULTS Of 20 participants, 17 completed the protocol. The median age was 72 years, most of the participants were men (80%), and most had spouses as caregivers. The Epworth Sleepiness Scale (p < 0.001), Maintenance of Wakefulness Test (p = 0.003), and Clinical Global Impression of Change (p < 0.001) scores improved at week 12. The Neuropsychiatric Inventory total score (p = 0.003), visual hallucinations (p = 0.003), and agitation (p = 0.02) improved at week 4. Caregiver overall quality of life improved at week 12 (p = 0.004). No adverse events occurred. CONCLUSION These pilot data suggest improvements in hypersomnia and wakefulness and reasonable safety and tolerability of armodafinil therapy in hypersomnolent patients with DLB. Our findings inform the use of pharmacologic strategies for managing hypersomnolence in these patients.

Abstract
OBJECTIVE To characterise the differences in caregiver distress between carers of people diagnosed with dementia with Lewy bodies (DLB) and people with Alzheimer's disease (AD), with a view to differentiating and improving support for caregivers. METHODS This study is a part of two larger Norwegian studies, DemVest (n = 265) and The Norwegian Dementia Register (n = 2220), with data from caregivers and people diagnosed with AD (n = 100) and DLB (n = 86) between 2005 and 2013. The average age was 74.9 years (SD = 7.8). Caregiver distress was rated by the Relative Stress Scale. Diagnosis of the person receiving care was based on a comprehensive standardised assessment program (International Classification of Diseases, Revision 10 or Diagnostic and Statistical Manual for Mental Disorders, fourth edition). Additional data collected from people receiving care were neuropsychiatric symptoms, comorbidity and activities of daily living (ADL) score. Linear regression analyses were applied, first unadjusted and then in stepwise-adjusts in addition to descriptive analyses. RESULTS Caregivers to people with AD (20.2%) and 40% of caregivers for people with DLB experienced moderate or high caregiver burden with an increased risk of psychiatric disorders in the early stage of dementia. High Relative Stress Scale (RSS) total scores in caregivers was significantly associated with neuropsychiatric symptoms (Neuropsychiatric Inventory, p = 0.004) and also with impaired ADL functioning (Rapid Disability Rating Scale-2, p < 0.0005). CONCLUSION Caregiver distress differed (RSS total, p = 0.005) between people caring for someone with AD (15.0) and those caring for someone with DLB (19.9). These findings have direct implications for the needs and resources that could be available for these individuals and indicate the need for further research into caregiver burden in carers to people with DLB.

Abstract
Abstract. Apathy is a diminished goal-directed behavior stemming from a lack of motivation. It is one of the most common symptoms in dementia. While the Apathy Evaluation Scale (AES) has proved to be a psychometrically robust measure for assessing apathy, the German version (AESD) requires further validation. Associations of apathy with important variables in dementia care, such as cognitive impairment or caregiver burden, were repeatedly found, though contradictory findings have also been reported. The present study assessed apathy in 100 community-dwelling persons with dementia. Their informal and formal caregivers used the German informant version of the Apathy Evaluation Scale (AESD-I) to investigate the severity of dementia and cognitive deficits as measured with the Mini-Mental State Examination (MMSE) and Global Deterioration Scale (GDS), respectively. A reliability analysis was performed to estimate the internal consistency of the AESD-I, and the data were tested for potential correlations with results from a shortened version of the AESD-I (AESD16-I). Cronbach’s α was .880 for the AESD-I and .904 for the AESD16-I. The prevalence of apathy was 77%, its severity was on average moderate to high. Significant (p < .05) negative correlations were shown between the AESD16-I, the Barthel Index (BI), and the Quality of Life-Alzheimer’s Disease (QOL-AD). Correlations between the AESD16-I, GDS, and Zarit Burden Interview were positive. After Bonferroni correction, the only correlations that remained significant were between the AESD16-I and BI and QOL-AD. The present study underlines the favorable psychometric properties of the AESD-I and confirms the high prevalence of apathy with considerable severity in the sample of community-dwelling persons with dementia. In addition, it contributes to the diversity of evidence on clinical correlates of apathy which require further clarification.

Abstract
Background: The ability to perform instrumental activities of daily living deteriorates early in dementia and affects people with dementia and their carers. However, little is known about individual instrumental activities of daily living impairments. This study therefore investigated instrumental activities of daily living deficits in mild dementia by exploring the relationship between instrumental activities of daily living initiative and performance and general cognition, people with dementia quality of life and carer stress. Moreover, this study explored the contribution of social instrumental activities of daily livings, which to date have received little or no attention. Methods: Twenty carers were administered a revised Interview for Deterioration for Daily Living Activities in Dementia and measures of carer stress (General Health Questionnaire-12) and quality of life in dementia (Quality of Life in Alzheimer’s Disease). The people with dementia completed measures of general cognition (Mini-Mental State Examination and Montreal Cognitive Assessment). Data were analysed using frequency and bivariate correlation analyses and basic thematic analysis was employed to the qualitative data on carer stress. Results: Carer interviews showed that instrumental activities of daily living impairments were associated more with performance than with initiative deficits. Increased social isolation and reluctance to engage in hobbies were particularly stressful to carers and impacted negatively on the people with dementia quality of life, yet were not reported as critical in the qualitative assessment. Conclusions: This study shows that people with mild dementia are impaired to different degrees on their initiative and performance of instrumental activities of daily livings and that impairments relating to social activities particularly relate to well-being. The revised Interview for Deterioration for Daily Living Activities in Dementia with its social instrumental activities of daily livings can help shift the focus of interventions to address those activities that are frequently impaired in mild dementia and relate to people with dementia and carer well-being.

Abstract
Background Visual hallucinations are a core clinical feature of dementia with Lewy bodies (DLB), and this symptom is important in the differential diagnosis and prediction of treatment response. The pareidolia test is a tool that evokes visual hallucination-like illusions, and these illusions may be a surrogate marker of visual hallucinations in DLB. We created a simplified version of the pareidolia test and examined its validity and reliability to establish the clinical utility of this test. Methods The pareidolia test was administered to 52 patients with DLB, 52 patients with Alzheimer’s disease (AD) and 20 healthy controls (HCs). We assessed the test-retest/inter-rater reliability using the intra-class correlation coefficient (ICC) and the concurrent validity using the Neuropsychiatric Inventory (NPI) hallucinations score as a reference. A receiver operating characteristic (ROC) analysis was used to evaluate the sensitivity and specificity of the pareidolia test to differentiate DLB from AD and HCs. Results The pareidolia test required approximately 15 minutes to administer, exhibited good test-retest/inter-rater reliability (ICC of 0.82), and moderately correlated with the NPI hallucinations score (rs = 0.42). Using an optimal cut-off score set according to the ROC analysis, and the pareidolia test differentiated DLB from AD with a sensitivity of 81% and a specificity of 92%. Conclusions Our study suggests that the simplified version of the pareidolia test is a valid and reliable surrogate marker of visual hallucinations in DLB.
