Dementia is common in older adults, with Alzheimer's disease (AD) being the most frequent cause. Risk factors include age, female sex, low education, and socioeconomic status.
Area of Science:
- Epidemiology
- Geriatrics
- Neurology
Context:
- An epidemiological survey was conducted in Shanghai's Jingan district, examining 5055 individuals aged 55 and above.
- The study utilized established diagnostic criteria for dementia (DSM-III-R) and Alzheimer's disease (NINCDS-ADRDA).
Purpose:
- To determine the prevalence of dementia and Alzheimer's disease in an elderly Chinese population.
- To identify associated risk factors for dementia in this demographic.
Summary:
- Dementia prevalence was 2.57% (≥55), 3.46% (≥60), and 4.61% (≥65).
- Alzheimer's disease prevalence was 1.50% (≥55), 2.05% (≥60), and 2.90% (≥65).
- Key risk factors identified include advanced age, female sex, spousal bereavement, lower educational attainment, and unfavorable socioeconomic status.
Impact:
- Highlights the significant public health burden of dementia and AD in aging populations.
- Provides crucial data for targeted prevention and intervention strategies in Shanghai and similar communities.
- Informs healthcare policy and resource allocation for geriatric care and neurodegenerative disease management.
