Dementia AND older e

Polypharmacy is an important issue in older patients affected by dementia because they are very vulnerable to the side effects of drugs'. Between October 2021 and September 2022, we randomly assessed 205 old-aged outpatients. The study was carried out in a Center for Dementia in collaboration with a university center. The primary outcomes were: (1) deprescribing inappropriate drugs through the Beers and STOPP&START criteria; (2) assessing duplicate drugs and the risk of iatrogenic damage due to drug-drug and drug-disease interactions...

BACKGROUND AND OBJECTIVES: Sporadic cerebral small vessel disease (CSVD) is a class of important pathologic processes known to affect the aging brain and to contribute to cognitive impairment. We aimed to identify clinical risk factors associated with postmortem CSVD in middle-aged to older adults. METHODS: We developed and tested risk models for their predictive accuracy of a pathologic diagnosis of nonamyloid CSVD and cerebral amyloid angiopathy (CAA) in a retrospective sample of 160 autopsied cases from the Edinburgh Brain Bank...

BACKGROUND AND OBJECTIVES: There are racial disparities in health care services received by patients with neurodegenerative diseases, but little is known about disparities in the last year of life, specifically in high-value and low-value care utilization. This study evaluated racial disparities in the utilization of high-value and low-value care in the last year of life among Medicare beneficiaries with dementia or Parkinson disease. METHODS: This was a retrospective, population-based cohort analysis using data from North and South Carolina fee-for-service Medicare claims between 2013 and 2017...

Providing opportunities for older adults to engage in physical and mental activity is important to support healthy aging. The present preliminary study investigated the feasibility of accessible chair yoga for older adults in care homes. Chair yoga participants ( n = 17) were assessed before and after attending twice weekly chair yoga sessions for 8 weeks, while control participants ( n = 16) underwent the assessments only. Participant ages ranged from 80 to 101 years and included those living with mild to severe dementia...

Sarcopenia refers to age-related loss of muscle mass and function and is related to impaired somatic and brain health, including cognitive decline and Alzheimer's disease. However, the relationships between sarcopenia, brain structure and cognition are poorly understood. Here, we investigate the associations between sarcopenic traits, brain structure and cognitive performance. We included 33 709 UK Biobank participants (54.2% female; age range 44-82 years) with structural and diffusion magnetic resonance imaging, thigh muscle fat infiltration ( n = 30 561) from whole-body magnetic resonance imaging (muscle quality indicator) and general cognitive performance as indicated by the first principal component of a principal component analysis across multiple cognitive tests ( n = 22 530)...

BACKGROUND AND OBJECTIVE: Following the outbreak of viral infections from the severe acute respiratory syndrome coronavirus 2 virus in 2019 (coronavirus disease 2019 [COVID-19]), reports emerged of long-term neurologic sequelae in survivors. To better understand the burden of neurologic health care and incident neurologic diagnoses in the year after COVID-19 vs influenza, we performed an analysis of patient-level data from a large collection of electronic health records (EMR). METHODS: We acquired deidentified data from TriNetX, a global health research network providing access to EMR data...

BACKGROUND: Depression is common amongst older people residing in long-term care (LTC) facilities. Currently, most residents treated for depression are prescribed antidepressant medications, despite the potential availability of psychological therapies that are suitable for older people and a preference amongst many older people for non-pharmacological treatment approaches. OBJECTIVES: To assess the effect of psychological therapies for depression in older people living in LTC settings, in comparison with treatment as usual, waiting list control, and non-specific attentional control; and to compare the effectiveness of different types of psychological therapies in this setting...

INTRODUCTION: This study investigates the relationship between microglia inflammation in the hippocampus, brain pathologies, and cognitive decline. METHODS: Participants underwent annual clinical evaluations and agreed to brain donation. Neuropathologic evaluations quantified microglial burden in the hippocampus, amyloid beta (Aβ), tau tangles, and limbic age-related transactive response DNA-binding protein 43 (TDP-43) encephalopathy neuropathologic changes (LATE-NC), and other common brain pathologies...

BACKGROUND: The prevalence of type 2 diabetes is increasing with the burden disproportionately falling on older adults and racial/ethnic minorities. Older adults with diabetes show greater cognitive decline and there are disparities in cognitive function by race/ethnicity that can be explained by social determinants such as wealth. OBJECTIVE: To understand whether there is a differential relationship between wealth and cognitive function by race/ethnicity among older U...

Physical activity is a promising preventative strategy for Alzheimer's disease: it is associated with lower dementia risk, better cognition, greater brain volume and lower brain beta-amyloid. Blood-based biomarkers have emerged as a low-cost, non-invasive strategy for detecting preclinical Alzheimer's disease, however, there is limited literature examining the effect of exercise (a structured form of physical activity) on blood-based biomarkers. The current study investigated the influence of a 6-month exercise intervention on levels of plasma beta-amyloid (Aβ42, Aβ40, Aβ42/40), phosphorylated tau (p-tau181), glial fibrillary acidic protein (GFAP) and neurofilament light (NfL) chain in cognitively unimpaired older adults, and as a secondary aim, whether blood-based biomarkers related to cognition...

INTRODUCTION: White matter hyperintensities (WMHs) are an important imaging marker for cerebral small vessel diseases, but their risk factors and cognitive associations have not been well documented in populations of different ethnicities and/or from different geographical regions. METHODS: We investigated how WMHs were associated with vascular risk factors and cognition in both Whites and Asians, using data from five population-based cohorts of non-demented older individuals from Australia, Singapore, South Korea, and Sweden ( N  = 1946)...

OBJECTIVES: This study provides one of the first national longitudinal studies of the association between caring for grandchildren (i.e., grandparenting) and the risk of dementia in the U.S., with a focus on gender-specific variations. METHOD: We estimated discrete-time event history models, drawing upon data from the Health and Retirement Study (2000-2016). The analytic sample included 10,217 community-dwelling White and Black grandparents aged 52 years and older at baseline...

OBJECTIVES: HFE haemochromatosis genetic variants have an uncertain clinical penetrance, especially to older ages and in undiagnosed groups. We estimated p.C282Y and p.H63D variant cumulative incidence of multiple clinical outcomes in a large community cohort. DESIGN: Prospective cohort study. SETTING: 22 assessment centres across England, Scotland, and Wales in the UK Biobank (2006-2010). PARTICIPANTS: 451 270 participants genetically similar to the 1000 Genomes European reference population, with a mean of 13...

OBJECTIVES: Several genetic factors have been associated with cognitive decline in aging. Apolipoprotein E (ApoE) ε4 has been widely studied in the risk for pathological cognitive decline, including dementia. However, the association between ApoE ε4 and cognitive functioning in the healthy aging Indian population has been understudied, and the results are ambiguous. MATERIALS AND METHODS: This study aims to examine the role of the ApoE genotype with attentional function in aging adults (≥45 years) in a rural Indian population...

INTRODUCTION: Apolipoprotein E E4 allele (APOE E4) and slow gait are independently associated with cognitive impairment and dementia. However, it is unknown whether their coexistence is associated with poorer cognitive performance and its underlying mechanism in neurodegenerative diseases. METHODS: Gait speed, APOE E4, cognition, and neuroimaging were assessed in 480 older adults with neurodegeneration. Participants were grouped by APOE E4 presence and slow gait...

OBJECTIVES: To investigate indicators of potentially hazardous alcohol use among older adults living in a region with high substance use stigma. METHODS: Patients at a university-affiliated geriatrics clinic in the Deep South of theUS completed behavioral health screenings including self-reported alcohol use, symptoms of depression or anxiety, and cognitive functioning between 2018 and 2022. RESULTS: Participants ( N  = 278) averaged 76...

Compared to younger adults, older adults who smoke cigarettes are half as likely to make a quit attempt, but more likely to maintain abstinence using evidence-based smoking treatments (EBSTs), illustrating the need for motivational messages to promote cessation through EBSTs. It is unclear whether messaging regarding the association between smoking and dementia might motivate older adults to quit. We conducted 90-min semi-structured qualitative interviews and surveys via telephone with 24 U.S. older adults who smoke (ages 50-75) with no cognitive impairment history...

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD), a common neurodevelopmental condition now recognized to persist into older adulthood, has been postulated to be a risk factor for neurocognitive disorders given the overlap in clinical features and neurobiology, as well as the complex interplay between ADHD and known risk factors for dementia. Studies have emerged assessing this relationship, but there has not yet been a comprehensive systematic review addressing this topic...

BACKGROUND: Adult day services (ADS) are an important and often underutilized support resource for older adults. For persons living with dementia (PLWD), ADS is an optimal access point to not only receive therapeutic and rehabilitative activities, but as a vehicle for respite/relief for dementia caregivers. Yet, there is currently a lack of research on integrating caregiver interventions into home and community-based services such as ADS. OBJECTIVE: This paper reports on qualitative findings from the Improving Outcomes for Family Caregivers of Older Adults with Complex Conditions: The Adult Day Plus (ADS Plus) Program Trial...

Background/Purpose: Older patients living with dementia and their caregivers are ideal beneficiaries of telemedicine, cost-effectiveness, caregiver satisfaction, and physician acceptance. The aim is to study the effect of a telemedicine dementia enabled program on the health outcome of dementia patients and their caregivers, as regard the patient outcome, caregiver stress, and caregiver satisfaction. Methods: Ninety-seven ( n  = 97) elderly subjects were recruited from the outpatient clinics and inpatient ward of Geriatrics Hospital, Ain Shams University Hospitals...
