Impact of sociodemographic characteristics on cognitive performance in an elderly Sicilian population.
2002
<i>Objective:</i> To assess cognitive levels in an elderly Sicilian population and to evaluate the role of education and other sociodemographic characteristics in cognitive performance. <i>Background:</i> The pattern of cognitive performance in the elderly has not been investigated extensively in well-defined Italian populations. This study was conducted as part of a door-to-door survey of common neurologic disorders (the Sicilian Neuro-Epidemiologic Study project). <i>Methods:</i> Thirteen physicians administered an Italian version of the Short Portable Mental Status Questionnaire (SPMSQ) to all subjects aged 50 years or older who, on November 1, 1987, r…
Perceived Burden among Spouse, Adult Child and Parent Caregivers
2018
Aims To identify what factors are associated with the caregiver burden of spouse caregivers, adult child caregivers, and parent caregivers. Background Caregivers often feel stressed and perceive caregiving as a burden. The caregiver burden has been little studied from the perspective of the personal relationship between caregiver and care recipient. Design Cross-sectional study. Methods A random sample of 4,000 caregivers in Finland was drawn in 2014 and those who remained either spouse, adult child, or parent caregivers at data collection were included in the analysis (N = 1,062). Data collection included recipients' characteristics. Caregivers' perceived burden was measured using the Care…
Occurrence of cognitive impairment and dementia in the community: a 9-year-long prospective study.
2008
Objective: To determine incidence rates of non-dementia cognitive impairment, to examine the impact of attrition due to death on the observed incidence estimates, and to compare the observed and corrected estimates of non-dementia cognitive impairment with dementia incidence rates. Methods: A total of 1,435 persons without dementia aged 75+ from the Kungsholmen Project were evaluated for occurrence of dementia over 9 years. A total of 1,070 cognitively unimpaired subjects were also followed using amnestic mild cognitive impairment (aMCI) and other cognitive impairment, no dementia (OCIND) definitions. To correct the observed incidence rates for attrition due to death, cognitive status for s…
A population-based survey of cognitive performance in a Sicilian elderly community.
2010
<i>Background:</i> The global burden of neurodegenerative diseases is increasing. Previous studies reported differences related to age, gender and socioeconomic status. We calculated the cognitive performances of a Sicilian population aged 65 years or older, by means of a door-to-door population-based survey in Bagheria city, Sicily. <i>Methods:</i> A door-to-door survey was carried out in the city of Bagheria, Sicily (prevalence day September 30, 2006). A cohort of 2,200 persons was randomly stratified, obtaining a 25% sample of the whole population. Cognitive function was assessed by Mini Mental State Examination (MMSE). Percentile distributions by age, gender, edu…
Vitamin D deficiency predicts cognitive decline in older men and women: The Pro.V.A. Study
2014
Objective: To test the hypothesis that hypovitaminosis D is associated with a higher risk of cognitive decline over a 4.4-year follow-up in a large sample of older adults. Methods: This research was part of the Progetto Veneto Anziani (Pro.V.A.), an Italian populationbased cohort study of 1,927 elderly subjects. Serum 25-hydroxyvitamin D (25OHD) levels were measured at the baseline. Global cognitive function was measured with the Mini-Mental State Examination (MMSE); scores lower than 24 were indicative of cognitive dysfunction, and a decline of 3 or more points on the MMSE over the follow-up was considered as clinically significant. Analyses were adjusted for relevant confounders, includin…
Midlife Physical Activity and Cognition Later in Life : A Prospective Twin Study
2016
Background: Physical activity has been associated with a reduced risk of cognitive decline but the nature of this association remains obscure. Objective: To study associations between midlife physical activity and cognition in old age for a prospective cohort of Finnish twins. Methods: Physical activity in the Finnish Twin Cohort was assessed using questionnaire responses collected in 1975 and 1981. After a mean follow-up of 25.1 years, the subjects' (n = 3050; mean age 74.2; range 66-97) cognition was evaluated with a validated telephone interview. Both participation in vigorous physical activity, and the volume of physical activity, divided into quintiles, were used as predictors of cogni…
The Effect of Adherence to the Mediterranean Diet on Late-Life Cognitive Disorders: A Systematic Review
2020
Objectives: Although some results are conflicting, numerous investigations have demonstrated that the Mediterranean Diet (MedDiet) has positive effects on brain health. This review intends to provide an update on the scientific evidence regarding the effects of adherence to the MedDiet on late-life cognitive disorders. Design: A systematic review was performed. The PubMed and Scopus databases were searched for longitudinal studies and randomized controlled trials (RCTs) published between the databases’ inceptions and May 4, 2020. PRISMA guidelines were followed; the quality of the studies was assessed using version 2 of the Cochrane risk-of-bias tool for the RCTs and the Newcastle-Ottawa Sc…
Capacidade cognitiva de indivíduos com doença renal crônica: relação com características demográficas e clínicas
2013
Introdução: O comprometimento da cognição e memória (CM) é comum em indivíduos com Doença Renal Crônica (DRC) em hemodiálise, o que prejudica a aderência ao tratamento. Objetivo: Avaliar a capacidade cognitiva de indivíduos renais crônicos em hemodiálise por meio do Miniexame do Estado Mental (MEEM) e a relação com as características sociodemográficas e clínicas desses indivíduos. Métodos: Foram obtidas informações clínicas e sociodemográficas de 75 indivíduos. Para avaliação da MC, foi aplicado o MEEM, o qual foi analisado segundo os diversos pontos de corte propostos na literatura. Após classificar os participantes de acordo com as diferentes propostas e pelas causas da DRC, os indivíduos…
Dietary Approaches and Supplements in the Prevention of Cognitive Decline and Alzheimer';s Disease
2016
Age-associated cognitive decline and dementia are conditions in which there is deterioration in memory, thinking, and behavior, with profound effects on the ability to perform everyday activities and well-being. Even if dementia mainly affects older persons, it is not a normal part of aging. Alzheimer's disease accounts for 60-75% of dementia cases. The number of persons affected will increase in the next decades in parallel with aging of the world population. Hence, unless some approach is found to reduce age-related deterioration of cognitive functions, health care costs will continue to rise exponentially. There is a wealth of epidemiological evidence supporting a relationship between di…
Low-Dose Aspirin Use and Cognitive Function in Older Age: A Systematic Review and Meta-analysis
2017
Objectives:\ud \ud To investigate whether low-dose aspirin (<300 mg/d) can influence the onset of cognitive impairment or dementia in observational studies and improve cognitive test scores in randomized controlled trials (RCTs) in participants without dementia.\ud \ud Design:\ud \ud Systematic review and meta-analysis.\ud \ud Setting:\ud \ud Observational and interventional studies.\ud \ud Participants:\ud \ud Individuals with no dementia or cognitive impairment initially.\ud \ud Measurements:\ud \ud Odds ratios (ORs) and 95% confidence intervals (CIs), adjusted for the maximum number of covariates from each study, were used to summarize data on the incidence of dementia and cognitive impa…
