Objectives.
To review epidemiologic studies on the prevalence, incidence, and risk factors of dementia in sub-Saharan Africa (SSA).
Methods.
A MEDLINE search (from January 1992 to December 31, 2013) of epidemiologic studies, with no language restriction, was conducted using the keywords “dementia” or “Alzheimer’s” and “Africa.” We selected for review population and hospital-based studies that reported the prevalence, incidence, or risk factors of dementia in SSA in people aged 60 years and above.
References of selected articles were reviewed to identify additional relevant articles that met our selection criteria.
Results.
Of a total of 522 articles, 41 were selected and reviewed.
The reported prevalence of dementia in SSA varied widely (range: 2.29%–21.60%); Alzheimer’s disease was the most prevalent type of dementia.
Only two studies conducted in Nigeria reported incidence data.
Major risk factors identified include older age, female gender, cardiovascular disease, and illiteracy.
Conclusion.
Data on the epidemiology of dementia in SSA is limited.
While earlier studies reported a lower prevalence of dementia in older persons, recent studies have put these findings into question suggesting that dementia prevalence rates in SSA in fact parallel data from Western countries.
