Risk factors for dementia
Chen JH, Lin KP, Chen YC.. Journal of the Formosan Medical Association = Taiwan yi zhi, 2009-10-01
Topic: Brain imaging, connectivity and assessment
Dementia is a complex human disease. The incidence of dementia among the elderly population is rising rapidly worldwide. In the United States, Alzheimer's disease (AD) is the leading type of dementia and was the fifth and eighth leading cause of death in women and men aged > or = 65 years, respectively, in 2003. In Taiwan and many other counties, dementia is a hidden health issue because of its underestimation in the elderly population. In Western countries, the prevalence of AD increases from 1-3% among people aged 60-64 years to 35% among those aged > 85 years. In Taiwan, the prevalence of dementia for people aged > or = 65 years was 2-4% by 2000. Therefore, it is important to identify protective and risk factors for dementia to prevent this disease at an early stage. Several factors are related to dementia, e.g. age, ethnicity, sex, genetic factors, physical activity, smoking, drug use, education level, alcohol consumption, body mass index, comorbidity, and environmental factors. In this review, we focus on studies that have evaluated the association between these factors and the risk of dementia, especially AD and vascular dementia. We also suggest future research directions for researchers in dementia-related fields.

Key findings
- In Taiwan, the prevalence of dementia for people aged > or = 65 years was 2-4% by 2000.
- Therefore, it is important to identify protective and risk factors for dementia to prevent this disease at an early stage.
- Several factors are related to dementia, e.g. age, ethnicity, sex, genetic factors, physical activity, smoking, drug use, education level, alcohol consumption, body mass index, comorbidity, and environmental factors.
- In this review, we focus on studies that have evaluated the association between these factors and the risk of dementia, especially AD and vascular dementia.
- We also suggest future research directions for researchers in dementia-related fields.

Study details
- Evidence strengthLow
How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
