The relationship between statins and cognition in Parkinson's disease (PD) is poorly understood. Analyses were performed to determine associations between statin use and cross-sectional and longitudinal cognitive performance in PD. Neuropsychological tests, medication logs, and ratings of functional abilities were collected from 313 PD participants longitudinally. At baseline, statin users (SU; N = 129) were older, more likely male, and had shorter PD duration than non-statin users (NSU; N = 184). In Cross-sectional analysis, SU performed better on global cognition, Trails B, semantic fluency, and phonemic fluency tasks...

PURPOSE: The Drug Burden Index (DBI) is a tool to quantify the anticholinergic and sedative load of drugs. Establishing functional correlates of the DBI could optimize drug prescribing in patients with dementia. In this cross-sectional study, we determined the relationship between DBI and cognitive and physical functions in a sample of patients with dementia. METHODS: Using performance-based tests, we measured physical and cognitive functions in 140 nursing home patients aged over 70 with all-cause dementia...

CONTEXT: Older adults with advanced illness and associated symptoms may benefit from primary palliative care, but limited data exist to identify older adults in U.S. primary care to benefit from this care. OBJECTIVES: To describe U.S. primary care visits among adults 65 years and older with advanced illness. METHODS: Cross-sectional analysis of the National Ambulatory and Hospital Ambulatory Medical Care Surveys (2009-2011) was conducted using chi-square tests to compare visits without and with advanced illness to U...

Behavioural changes, often resulting in negative or challenging behaviour, are highly prevalent in patients with dementia. Here we describe two patients in whom challenging behaviour was the first sign of an evolving dementia process. We discuss the relevance of a multifactorial approach in analysis and treatment, starting from a biopsychosocial model of behaviour in dementia. One pitfall is underestimating the contribution of physical co-morbidity to challenging behaviour in these patients; a further pitfall is the 'attribution phenomenon', i...

Combined cognitive and physical exercise interventions have potential to elicit cognitive benefits in older adults with mild cognitive impairment (MCI) or dementia. This meta-analysis aims to quantify the overall effect of these interventions on global cognitive functioning in older adults with MCI or dementia. Ten randomized controlled trials that applied a combined cognitive-physical intervention with cognitive function as an outcome measure were included. For each study effect sizes were computed (i.e., post-intervention standardized mean difference (SMD) scores) and pooled, using a random-effects meta-analysis...

BACKGROUND: Affective and emotional symptoms such as depression, anxiety, euphoria, and irritability are common neuropsychiatric symptoms (NPS) in pre-dementia and cognitively normal older adults. They comprise a domain of Mild Behavioral Impairment (MBI), which describes their emergence in later life as an at-risk state for cognitive decline and dementia, and as a potential manifestation of prodromal dementia. This selective scoping review explores the epidemiology and neurobiological links between affective and emotional symptoms, and incident cognitive decline, focusing on recent literature in this expanding field of research...

Sleep disturbances and dementia are two common and significant health problems in older adults. Investigations suggest that sleep disturbances might increase the risk of dementia. The aim of the present study was to systematically review and meta-analyze the predictive roles of overall sleep disturbances, their subtypes (e.g., insomnia, sleep disordered breathing [SDB]), and other sleep problems (e.g., excessive daytime sleepiness, sleep-related movement disorder, circadian rhythm sleep disorder, and nonspecific sleep problems) in incident all-cause dementia and Alzheimer's disease (AD) and vascular dementia subtypes...

The relationship between obesity and cognitive impairment is important given the globally ageing population in whom cognitive decline and neurodegenerative disorders will carry grave individual, societal and financial burdens. This review examines the evidence for the link between obesity and cognitive function in terms of both the immediate effects on cognitive performance, and effects on the trajectory of cognitive ageing and likelihood of dementia. In mid-life, there is a strong association between obesity and impaired cognitive function...

BACKGROUND: Arterial stiffness is one of the earliest indicators of changes in vascular wall structure and function and may be assessed using various indicators, such as pulse-wave velocity (PWV), the cardio-ankle vascular index (CAVI), the ankle-brachial index (ABI), pulse pressure (PP), the augmentation index (AI), flow-mediated dilation (FMD), carotid intima media thickness (IMT) and arterial stiffness index-β. Arterial stiffness is generally considered an independent predictor of cardiovascular and cerebrovascular diseases...

BACKGROUND: US-based studies have reported that older blacks perform worse than older whites on cognitive tests and have higher risk of Alzheimer disease dementia (AD). It is unclear whether these findings reflect differences in cognitive decline. METHODS: The Chicago Health and Aging Project followed individuals, 65+ years old (64% black, 36% white), for up to 18 years. Participants underwent triennial cognitive assessments; stratified randomized samples underwent assessments for AD...

Study Objectives: Healthy physiology is characterized by fractal regulation (FR) that generates similar structures in the fluctuations of physiological outputs at different time scales. Perturbed FR is associated with aging and age-related pathological conditions. Shift work, involving repeated and chronic exposure to misaligned environmental and behavioral cycles, disrupts circadian coordination. We tested whether night shifts perturb FR in motor activity and whether night shifts affect FR in chronic shift workers and non-shift workers differently...

OBJECTIVE: The growing number of older adults with cognitive impairment is increasing the need for healthcare services. However, there is a great shortage of geriatric trained primary care providers and psychiatrists. A positive attitude towards people with cognitive impairment is associated with better quality of life among residents of long-term care settings. This led us to develop a simulation exercise to raise learners' awareness of, and attentiveness to, physical and cognitive changes experienced by the aging population...

OBJECTIVES: To improve the value of research for older adults, we examine sex-specific reporting of data from drug trials for the management of dementia. These data are important because they may influence considerations ranging from the health of populations to shared decision-making by individual patient and caregiver about the risk and benefit of a drug therapy. METHODS: Randomized controlled trials of cholinesterase inhibitors (i.e., donepezil, rivastigmine, or galantamine) with clinical outcomes were identified from searches of MEDLINE, EMBASE, and the Cochrane Library...

Because of the rapidly growing older population and increases in longevity, rates of dementia have been rising. Clinical challenges of treating dementia include limited resources and lack of curative therapies. Palliative care approaches improve quality of life and alleviate suffering for dementia patients at the end of life, although implementation may be limited by societal acceptance and feasibility. This review examines the published literature on pain assessments, pain and behavior interventions, tools for advanced care planning, and clinical concerns in dementia patients...

BACKGROUND: Patients with substance use disorders grow older thanks to effective treatments. Together with a high prevalence of comorbidities, psychological problems, and low social support, these patients are at high risk for medication non-adherence. Established treatment facilities face challenges to accommodate these complex patients within their setting. Electronic medication management aids (e-MMAs) might be appropriate to simultaneously monitor and improve adherence for these patients...

BACKGROUND: Antipsychotic medication can cause tardive dyskinesia (TD) - late-onset, involuntary, repetitive movements, often involving the face and tongue. TD occurs in > 20% of adults taking antipsychotic medication (first-generation antipsychotics for > 3 months), with this proportion increasing by 5% per year among those who continue to use these drugs. The incidence of TD among those taking newer antipsychotics is not different from the rate in people who have used older-generation drugs in moderate doses...

BACKGROUND: Little is known about how multimorbidity, dementia and increasing age combine to influence health outcomes or utilization. Our objective was to examine the joint associations between age, dementia and burden of morbidity with mortality and other clinical outcomes. METHODS: We did a retrospective population-based cohort study of all adults aged 65 years and older residing in Alberta, Canada, between 2002 and 2013. We used validated algorithms applied to administrative and laboratory data from the provincial health ministry to assess the presence/absence of dementia and 29 other morbidities, and their associations with mortality (our primary outcome), other clinical outcomes (emergency department visits, all-cause hospital admissions) and a proxy for loss of independent living (discharge to long-term care)...
