Abstract
As the older adult population expands, an increasing number of patients affected by geriatric syndromes are seen by cardiovascular clinicians. One such syndrome that has been associated with poor outcomes is cognitive frailty: the simultaneous presence of cognitive impairment, without evidence of dementia, and physical frailty, which results in decreased cognitive reserve. Driven by common pathophysiologic underpinnings (eg, inflammation and neurohormonal dysregulation), cardiovascular disease, cognitive impairment, and frailty also share the following risk factors: hypertension, diabetes, obesity, sedentary behavior, and tobacco use. Cardiovascular disease has been associated with the onset and progression of cognitive frailty, which may be reversible in early stages, making it essential for clinicians to diagnose the condition in a timely manner and prescribe appropriate interventions. Additional research is required to elucidate the mechanisms underlying the development of cognitive frailty, establish preventive and therapeutic strategies to address the needs of older patients with cardiovascular disease at risk for cognitive frailty, and ultimately facilitate targeted intervention studies.

Abstract
The aim of this scoping review was to present an overview of the existing epidemiological evidence in retired male and female elite rugby players regarding the prevalence rates of musculoskeletal, cardiovascular, neurocognitive, psychological and gynaecological health conditions. A systematic search was carried out across MEDLINE (via PubMed), SPORTDiscus (via EBSCOhost), PsycINFO (via EBSCOhost) and EMBASE for musculoskeletal (eg, osteoarthritis), cardiovascular (eg, hypertension), neurocognitive (eg, dementia) and psychological health (eg, disordered eating, alcohol misuse) conditions in retired elite male and female rugby players and gynaecological health conditions (menorrhagia) in retired female rugby players. Primary research studies describing the prevalence rates of health conditions in retired elite male and female rugby players written in English, Dutch or French and with full text available online were included. Five hundred and seventy-three citations were originally identified and 16 studies were ultimately included in our review. No studies on health conditions in retired elite female rugby players were found. Four individual studies showed there was a significant higher prevalence rate of osteoarthritis in retired elite male rugby players compared with control groups. Various neurocognitive health conditions were investigated and showed, among others, a prevalence rate of 57% for mild cognitive disorder. The prevalence of self-reported depression and hazardous alcohol use in retired elite male rugby players was significantly higher than in control groups matched for age and education. Our review found relatively high prevalence rates of musculoskeletal health conditions such as osteoarthritis and psychological health conditions such as depression and hazardous alcohol use in retired elite male rugby players. More research needs to be conducted to understand better the health conditions of retired elite rugby players, especially among retired elite female players.

Abstract
People living with dementia (PLWD) experience pain like other older adults, but with changes due to dementia, they rely more on family caregivers for pain assessment. Many different elements contribute to a pain assessment. Changes in characteristics of PLWD may be associated with changes in the use of these different pain assessment elements. The current study reports associations between PLWD's agitation, cognitive function, and dementia severity and the frequency with which family caregivers use pain assessment elements. In a sample of family caregivers (N = 48), statistically significant associations were found between worsening cognitive function and greater use of rechecking for pain after intervention (rho = 0.36, p = 0.013), and between lower cognitive scores on a subscale of dementia severity and asking others if they have noticed a behavior change in the PLWD (rho = 0.30, p = 0.044). Limited statistically significant associations suggest that, overall, family caregivers of PLWD do not use pain assessment elements more frequently with changes in characteristics of PLWD.

[PMID: 37166562 DOI: 10.1007/s40520-023-02429-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Accepted: 04/26/2023] [Indexed: 05/12/2023]
Abstract
BACKGROUND Delirium is associated with dementia, which shares symptoms of cognitive dysfunctions. Notably, pathological mechanisms of Alzheimer's disease (AD) appear involved in both conditions. Insulin resistance has been reported to be a risk factor for AD, leading to neurodegeneration and cognitive impairment by affecting amyloid-beta (Aβ) metabolism, tau phosphorylation, and neuro-inflammation. Thus, insulin resistance may provide pathophysiological clues to the occurrence of delirium. AIM To investigate the relationship between preoperative insulin resistance, insulin concentrations in the cerebrospinal fluid (CSF), and delirium in elderly patients with hip fracture. METHODS The study included 138 elderly patients with or without pre-existing dementia who underwent hip fracture surgery. Delirium was diagnosed with the confusion assessment method performed daily from pre-operation to 5 days post-operation. CSF and blood samples were collected at the beginning of spinal anesthesia. The concentrations of insulin, amyloid-beta1-42 (Aβ42), total tau (t-tau), and phosphorylated tau (p-tau)181 were determined by ELISA. Homeostasis model assessment (HOMA-IR) was used to assess insulin resistance. RESULTS Sixty-one (44%) of 138 hip fracture patients developed delirium peri-operatively. Compared to non-delirium group, the preoperative HOMA-IR index in delirium was much higher (median 3.3 vs 2.8, p = 0.001), but the CSF insulin concentration was significantly decreased (median 1.5 vs 2.2 mU/L, p < 0.001). Binary logistic regression analysis showed that HOMA-IR index and CSF insulin concentration were independent risk factors for delirium (p < 0.05). HOMA-IR index was negatively correlated with CSF insulin concentrations (rho = - 0.55, p < 0.001). Multiple linear regression analysis showed that AD core biomarkers were significantly correlated with HOMA-IR index and CSF insulin level (p < 0.05). CONCLUSION This study innovatively examined insulin concentrations in serum and cerebrospinal fluid in patients with delirium. Our findings suggest that preoperative insulin resistance may affect the occurrence of delirium. The potential association between insulin resistance and delirium may be related to insulin resistance affecting the metabolism of AD biomarkers.

Abstract
Primary care professionals play a critical role in the care of their patients. In clinical practice, early detection and diagnosis of Mild Cognitive Impairment, Alzheimer's disease and related dementia are often missed or delayed. Disclosure of diagnosis is not timely or not revealed. Though the methods that could improve early detection and diagnosis have remained the same over the decades with little change, they provide opportunities for early intervention, treatment and improvement in patient care. Emerging research suggests that though the disease process begins years prior to the clinical diagnosis, the healthcare system and health care professionals remain distant and reluctant to provide the service of annual cognitive assessment, which has been recommended by the Medicare program for older adults aged 65 years and older. Findings support that Alzheimer's disease and related cognitive impairments have gone under detected, underdiagnosed and undertreated. This article seeks to provide valuable and equitable information in the form of a clinician's guide for removing the barriers to early detection and diagnosis of cognitive impairments and offers an unprecedented opportunity to improve the clinical outcomes and care of older adults with various levels of cognitive decline, including mild cognitive impairment, Alzheimer's disease, and related dementias. This article provides information on understanding and addressing the challenges faced by health care professionals, including primary care clinicians; removing the barriers to cognitive assessments; educating this professional group on the importance of brain health, early detection, and diagnosis for their older adult patients; and providing these professionals with the ability to transfer their knowledge into more defined care planning. Until cognitive screening has been fully accepted and implemented for the optimal the care of older adults, health-related efforts should include the promotion and education of brain health, early detection, and diagnosis in the education of health care providers.

Abstract
Smartphones offer unique opportunities to trace the convoluted behavioral patterns accompanying healthy aging. Here we captured smartphone touchscreen interactions from a healthy population (N = 684, ∼309 million interactions) spanning 16 to 86 years of age and trained a decision tree regression model to estimate chronological age based on the interactions. The interactions were clustered according to their next interval dynamics to quantify diverse smartphone behaviors. The regression model well-estimated the chronological age in health (mean absolute error = 6 years, R2 = 0.8). We next deployed this model on a population of stroke survivors (N = 41) to find larger prediction errors such that the estimated age was advanced by 6 years. A similar pattern was observed in people with epilepsy (N = 51), with prediction errors advanced by 10 years. The smartphone behavioral model trained in health can be used to study altered aging in neurological diseases. A smartphone data-driven model was trained to estimate chronological age The model trained in health performed well to estimate the age The same model estimated advanced aging in stroke and epilepsy Smartphone-based model of healthy behavior may help understand aging in diseases

Abstract
BACKGROUND The relationship between diabetes mellitus and neurodegenerative disorders has been of great interest. Macrophage migration inhibitory factor (MIF) is a pro-inflammatory cytokine in which a variety of signaling cascades are activated through it. MIF has been involved in the pathogenesis of several diseases and can predict early pre-symptomatic stages of neurodegeneration in diabetic patients. OBJECTIVE To investigate whether serum MIF could predict brain neurodegeneration at the early pre-symptomatic stages in diabetic patients. METHODS We examined adults with type 2 diabetes mellitus and compared with normal control adults using a short form of the IQCODE and biochemical examination, including assessment of HA1C, fasting blood glucose, lipid profile, and MIF which was measured by ELISA technique. Correlations between parameters were studied. Computational PathLinker bioinformatic tool was used to search for potential pathway reconstructions for the insulin/amyloid-β/MIF signaling. RESULTS We demonstrated that MIF level was increased in the serum at the early pre-symptomatic stages of neurodegenerative disorder in diabetic patients. In addition, network analysis demonstrates that insulin receptor substrate 1 can ameliorate amyloid-β protein precursor through COP9 signalosome complex subunit 5 that enhances MIF elevation. CONCLUSION Diagnosis processes could not be used as routine examinations for still pre-symptomatic neurodegenerative disorders. This may be due to the time constraints and the heavy dependence on the physician's experience. Therefore, serum MIF level could predict brain neurodegeneration at the early pre-symptomatic stages in diabetic patients which may support its potential utility as a clinically useful biomarker.

Abstract
Background Perioperative neurocognitive disorder includes postoperative cognitive dysfunction (POCD) and postoperative delirium (POD). Concerning inconclusive consequences of POCD compared with POD, we explored the association between either POCD or POD and functional decline as well as healthcare utilization. Methods Patients aged at least 60 years who underwent a major operation were enrolled. POCD was defined as a decrease in the Montreal Cognitive Assessment (MoCA) score (≥ 2) 1 week after surgery. Postoperative delirium (POD) was defined according to the criteria of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The primary outcome was instrumental activities of daily living (IADLs) 3 months after discharge. Secondary outcomes were the length of stay (LOS), hospital cost, and factors that affected functional decline 3 months after surgery. The multivariate model, including potential confounding factors, namely age, gender, surgery type, and postoperative complications, was used to analyze possible factors that influenced a reduction in function, and the results were expressed by using adjusted relative risk (RR) and 95%CI. Results Two hundred eighty-nine patients with a mean age of 72 years were enrolled. The incidence of POCD at 1 week was 28.5%. At their 3-month follow-ups, the patients with POCD were not associated with IADL decline. Nevertheless, patients with POCD were more likely to need a prolonged LOS (11 days [1, 46] vs. 8 days [2, 42]; P = 0.01), and incur higher hospital costs (8973.43 USD [3481.69, 11 763.74] vs. 5913.62 USD [332.43, 19 567.33]; P < 0.001). Additionally, the patients experiencing POD demonstrated increased risks of reducing their IADLs (adjusted RR 2.33; 95% CI, 1.15–4.71; P = 0.02). Conclusions POCD at 1 week leaded to increase healthcare utilization in a middle-income country. POD during hospitalization was associated with a decline in function after surgery and increased health care utilization. Trial registration Thai Clinical Trials Registry TCTR20190115001.

Abstract
OBJECTIVE As part of the fifth Canadian Consensus Conference on the Diagnosis and Treatment of Dementia, we assessed the literature on informant-based tools for assessment and monitoring of cognition, behavior, and function in neurocognitive disorders (NCDs) to provide evidence-based recommendations for clinicians and researchers. METHODS A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards guidelines. Publications that validated the informant-based tools or described their key properties were reviewed. Quality of the studies was assessed using the modified Quality Assessment tool for Diagnostic Accuracy Studies. RESULTS Out of 386 publications identified through systematic search, 34 that described 19 informant-based tools were included in the final review. Most of these tools are backed by good-quality studies and are appropriate to use in clinical care or research. The tools vary in their psychometric properties, domains covered, comprehensiveness, completion time, and ability to detect longitudinal change. Based on these properties, we identify different tools that may be appropriate for primary care, specialized memory clinic, or research settings. We also identify barriers to use of these tools in routine clinical practice. CONCLUSION There are several good-quality tools available to collect informant-report for assessment and monitoring of cognition, behavior, or function in patients with NCDs. Clinicians and researchers may choose a particular tool based on their specific needs such as domains of interest, desired psychometric properties, and feasibility. Further work is needed to make the tools more user-friendly and to adopt them into routine clinical care.

Abstract
Introduction: Dementia is a known risk factor for both delirium and acute systemic infections which may also play a significant role in promoting or accelerating neurodegenerative disease. Infections are both the main causes of hospitalization of dementia patients and can be a major precipitant of delirium but currently it is not possible to predict the risk of cognitive decline in older patients exposed to acute infection. Objectives: We aimed to determine the level of cognitive change at 1-year follow up in individuals with different patterns of cognitive function (dementia, delirium, delirium superimposed on dementia) at the time of their hospitalization due to a systemic infection and to correlate these cognitive patterns with clinical status variables. Methods: We recruited 53 hospitalized geriatric patients with a systemic infection, and we collected 12-months follow up data for 34 patients. These patients were classified in four groups: no cognitive impairment (controls-C), delirium only (D), dementia only (Dem), and delirium superimposed to dementia (DD). Cognitive performance was measured by change in score on the Montreal Cognitive Assessment (MoCA) and delirium was identified using Confusion Assessment Measure (CAM). We examined performance on the MoCA in the first year after hospitalization, controlling for demographic characteristics, coexisting medical conditions, and type of infection. Results: For the 34 patients to whom follow-up data was available, delirium presence in individuals with prior dementia (DD group) was associated with a negative mean change score of 3-point (p < 0.02) at 1 year follow up, whereas dementia patients without delirium had a mean change score of 1.5-point lower at 12-months (p = 0.04), when comparing follow-up and baseline MoCA scores. Cognitively healthy patients did not significantly decrease their MoCA score at follow-up (p = 0.15). MoCA and NPI scores during hospitalization were significantly correlated with the level of cognitive decline in the four groups (r = 0.658, p < 0.01 and r = 0.439, p = 0.02, respectively). Conclusions: Premorbid dementia and delirium superimposed on dementia during hospitalization in older patients with acute infections predict cognitive decline at 1 year following admission. Taken together, our findings suggest a pathophysiological interaction between neurodegenerative changes, acute infection, and delirium.

Abstract
BACKGROUND Rapidly progressive dementia (RPD) is a clinical syndrome developing in <1 to 2 years. Recent progress in RPD evaluation is significant, so RPD's prevalence may change over time. The aim of our new case series was to estimate the relative frequency of RPDs' causative entities, considering the recent advances in RPDs' diagnosis, and compare the results with those of our previous report. PATIENTS AND METHODS We retrospectively reviewed the medical records of 47 patients who were referred to Attikon University Hospital during a 5-year period for a suspected RPD. RESULTS Neurodegenerative diseases were the most frequent causes (38%), followed by prion disease (19%) and autoimmune encephalopathy (AE, 17%). AE cases were by far more common than in our previous report, while other than AE secondary causes were significantly decreased. Mean time to dementia was 9 months in neurodegenerative diseases and 5 months in non-neurodegenerative. Main clinical findings across all patients were memory impairment (66%) and behavioral-emotional disturbances (48%). CONCLUSIONS Neurodegenerative diseases are common causes of RPD and have a slower evolution than non-neurodegenerative. Diagnostic novelties enabled the recognition of AE, whereas more common secondary causes are probably now diagnosed in primary settings since the recognition of RPD as distinct clinical entity is continually increasing.

Abstract
OBJECTIVE The utility of informant-based measures of cognitive decline to accurately describe objective cognitive performance in Parkinson's disease (PD) without dementia is uncertain. Due to the clinical relevance of this information, the purpose of this study was to examine the relationship between informant-based reports of patient cognitive decline via the Informant Questionnaire of Cognitive Decline in the Elderly (IQCODE) and objective cognition in non-demented PD controlling for cognitive status (i.e., mild cognitive impairment; PD-MCI and normal cognition; PD-NC). METHOD One-hundred and thirty-nine non-demented PD participants (PD-MCI n = 38; PD-NC n = 101) were administered measures of language, executive function, attention, learning, delayed recall, visuospatial function, mood, and motor function. Each participant identified an informant to complete the IQCODE and a mood questionnaire. RESULTS Greater levels of informant-based responses of patient cognitive decline on the IQCODE were significantly associated with worse objective performance on measures of global cognition, attention, learning, delayed recall, and executive function in the overall sample, above and beyond covariates and cognitive status. However, the IQCODE was not significantly associated with language or visuospatial function. CONCLUSIONS Results indicate that informant responses, as measured by the IQCODE, may provide adequate information on a wide range of cognitive abilities in non-demented PD, including those with MCI and normal cognition. Findings have important clinical implications for the utility of the IQCODE in the identification of PD patients in need of further evaluation, monitoring, and treatment.

Abstract
BACKGROUND/OBJECTIVES The diagnostic process in a university memory clinic is based largely on cognitive testing. However, input from informants, acquired through interview or questionnaires, may significantly impact diagnosis. We sought to evaluate whether informant questionnaires for basic and instrumental activities of daily living, or for identifying progressive cognitive decline would improve diagnostic predictability of neurodegenerative disorders compared with either the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) neuropsychological test battery or the Mini-Mental State Examination score alone. DESIGN Retrospective data analysis using logit models. SETTING University hospital outpatient memory clinic. PARTICIPANTS A total of 394 patients with dementia, mild cognitive impairment (MCI), depression, or subjective cognitive impairment were assessed. MEASUREMENTS Bristol Activities of Daily Living Scale, Functional Activities Questionnaire, Informant Questionnaire on Cognitive Decline in the Elderly, and the Physical Self-Maintenance Scale questionnaires were obtained. Analyses through logit models were performed to predict outcome diagnoses, based on cognitive scores alone or in combination with one or more informant questionnaires. RESULTS The four questionnaires were highly correlated (.31-.86). The addition of informant questionnaires improved diagnostic predictability between differential diagnoses of MCI and dementia, or dementia and depression. However, the misprediction rate was reduced by up to 6 percentage points only. Adding more than one questionnaire or all CERAD subtests instead of their sum score never improved prediction in regularized logit models to a clinically relevant extent. CONCLUSION Although questionnaires contribute to a statistically better prediction of the outcome diagnosis, for some sets of differential diagnoses, the benefit may not be clinically pertinent when routine semistructured informant interviews are used by trained personnel. However, standardized assessment, particularly when patients are seen longitudinally, should not be underestimated.

Abstract
Alzheimer's disease (AD) dementia refers to a particular onset and course of cognitive and functional decline associated with age together with a particular neuropathology. It was first described by Alois Alzheimer in 1906 about a patient whom he first encountered in 1901. Modern clinical diagnostic criteria have been developed, and criteria have also been proposed to recognize preclinical (or presymptomatic) stages of the disease with the use of biomarkers. The primary neuropathology was described by Alzheimer, and in the mid-1980s subsequently evolved into a more specific neuropathologic definition that recognizes the comorbid neuropathologies that frequently contribute to clinical dementia. Alzheimer's disease is now the most common form of neurodegenerative dementia in the United States with a disproportionate disease burden in minority populations. Deficits in the ability to encode and store new memories characterizes the initial stages of the disease. Subsequent progressive changes in cognition and behavior accompany the later stages. Changes in amyloid precursor protein (APP) cleavage and production of the APP fragment beta-amyloid (Aβ) along with hyperphosphorylated tau protein aggregation coalesce to cause reduction in synaptic strength, synaptic loss, and neurodegeneration. Metabolic, vascular, and inflammatory changes, as well as comorbid pathologies are key components of the disease process. Symptomatic treatment offers a modest, clinically measurable effect in cognition, but disease-modifying therapies are desperately needed.
