The looming epidemic of stroke and other chronic non-communicable diseases associated with lifestyle and demographic transitions occurring all over the world is increasingly being acknowledged. However, the significance of these trends in the relatively young populations of the countries comprising Sub-Saharan Africa (SSA) is less certain and considerably overshadowed by attention given to the impact of human immunodeficiency virus and other infectious diseases. We undertook a literature review of the burden of stroke in SSA and provide recommendations for future research. Despite the paucity of high quality studies, the mostly hospital-based data and limited community surveys indicate there to be high and increasing rates of stroke affecting people at much younger ages in SSA than in developed countries. In general, awareness, diagnosis and management of stroke are poor, and the associated case fatality and residual disability are high. As elsewhere, elevated blood pressure is the major determinant of stroke but there are also high rates of strokes related to the complications of rheumatic heart disease and other infections. Given high attributable risks exposures in association with rapid ageing and urbanisation in SSA, the future is not bright. Population-based incidence studies are urgently needed to map the profile and outcome of stroke. Such data would provide the necessary evidence base to improve prevention and treatments for stroke alongside current efforts to bring infectious diseases under control in SSA.
