Summary
Dementia prevalence and risk factors in Chinese populations are similar to other ethnic groups. However, more longitudinal studies are needed to understand dementia incidence and prognosis in this demographic.
Area of Science:
- Neurology
- Epidemiology
- Public Health
Background:
- Dementia prevalence varies across ethnic groups globally.
- Epidemiological data on dementia in Chinese populations remain limited.
- Existing reviews offer insights but lack focus on Chinese demographics.
Purpose of the Study:
- To review epidemiological studies on dementia in worldwide Chinese populations.
- To analyze prevalence, incidence, risk factors, and prognosis.
- To identify research gaps and future directions.
Main Methods:
- Searched PubMed and Web of Science for English articles up to July 2013.
- Included original research on prevalence, incidence, risk factors, and prognosis.
- Focused on population-based follow-up studies for incidence, risk factors, and prognosis.
Main Results:
- Identified 25 studies on elderly Chinese in Mainland China, Hong Kong, Taiwan, and Singapore.
- Higher dementia prevalence in Mainland China potentially due to more recent studies.
- Increased incidence observed with 10/66 diagnostic criteria; age, gender, education, smoking, and alcohol linked to risk.
Conclusions:
- Dementia prevalence, incidence, and risk factors in Chinese populations are comparable to other ethnic groups.
- Diagnostic criteria and study timelines influence prevalence and incidence findings.
- More longitudinal population-based studies are required for incidence and prognosis in Chinese populations.

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.

01:22Dementia l: Introduction
35
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...

01:29Alzheimer Disease l: Introduction
21
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...

01:26Alzheimer's Disease: Overview
1.7K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

1.3K
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
