Stroke in Africa: profile, progress, prospects and priorities

Area of Science:

• Neurology
• Public Health
• Epidemiology

Background:

• Stroke is a major global cause of death and disability, with a significant burden in low- and middle-income countries.
• Historically, communicable diseases dominated Africa's health landscape, but non-communicable diseases like stroke are now increasingly prevalent.
• Africa may experience 2-3 times higher stroke incidence and prevalence compared to Western Europe and the USA.

Purpose of the Study:

• To review the unique profile of stroke in Africa.
• To summarize current knowledge on stroke epidemiology, genetics, prevention, care, and outcomes on the continent.
• To identify knowledge gaps, emerging priorities, and future directions for stroke medicine in Africa.

Main Methods:

• Review of recent epidemiological data on stroke in Africa.
• Synthesis of current research on stroke genetics, prevention strategies, and acute care.
• Analysis of rehabilitation, outcomes, cost of care, and awareness levels.

Main Results:

• Annual stroke incidence rates in Africa can reach up to 316 per 100,000.
• Stroke prevalence in Africa can be as high as 1,460 per 100,000.
• The 3-year fatality rate for stroke in Africa exceeds 80%, often occurring in individuals aged 40-60.

Conclusions:

• Stroke poses a significant and growing challenge in Africa, distinct from its profile in high-income nations.
• The younger age of stroke onset in Africa has profound socioeconomic implications.
• Addressing the escalating stroke burden requires targeted research, improved prevention, and enhanced healthcare strategies across the continent.
