Abstract

To investigate the dementia prevalence in a country with high levels of cardiovascular risk factors DESIGN AND METHODS: Older people in Trinidad are recognised to have particularly high levels of cardiovascular risk factors. We carried out a survey in a nationally representative sample of people aged ≥70 years using household enumeration. Dementia status was ascertained using standardised interviews and algorithms from the 10/66 schedule and age-specific prevalence were compared with identically defined output from the 10/66 surveys of 16 536 residents in eight other low-income and middle-income countries. Of 1832 participants (77.0% response rate), dementia was present in 442 (23.4%). Prevalences were 12.0% in persons aged 70-74 years, 23.5% at 75-79, 25.8% at 80-84, 41.3% at 85-89 and 54.0% in those aged ≥90 years. Prevalence ratios compared with averages from 10/66 surveys in these age groups were 2.2, 2.6, 1.6, 1.7 and 1.6, respectively, and were 2.7, 2.8, 1.7, 1.4 and 0.8, respectively, compared with previously published consensus estimates for the Latin American region. Dementia was significantly associated with reported stroke and diabetes in logistic regression models adjusted for sociodemographic status and other vascu...Continue Reading

Age-related Dementia

Dementias are a group of conditions, including Alzheimer's disease, vascular dementia, and frontotemporal dementia, characterized by deficiencies in cognitive abilities. Age-related dementia refers to dementias that occur in older individuals, usually 60+ years old, in contrast to early-onset dementia. Follow the latest research on age-related dementia here.

Aging & Diabetes

This feed focuses on the role of the aging process on developing diabetes.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Aging-Associated Metabolic Disorders

Age is associated with many metabolic disorders including cardiovascular diseases, type 2 diabetes, stroke and heart disease. The mediators in aging process have been suggested to play a part in the cellular processes responsible for these metabolic disorders. Here is the latest research on aging-associated metabolic disorders.

Cell Aging (Keystone)

This feed focuses on cellular aging with emphasis on the mitochondria, autophagy, and metabolic processes associated with aging and longevity. Here is the latest research on cell aging.

Aging Epidemiology

This feed focuses on epidemiology of aging and aging-related conditions, including Alzheimer’s disease, dementia, and age-associated cognitive impairment. Here is the latest research.
