Stroke is one of the most devastating neurological conditions in Africa, with a pattern that is fundamentally different from high-income countries. Africans experience strokes at younger ages, with more severe outcomes, and with significantly limited access to treatment and rehabilitation services.
Statistics on the African stroke burden.

| 3-year stroke fatality rate | Up to 84% | Okekunle et al., 2023 |
| 1-month case fatality | 24.45% | Okekunle et al., 2023 |

Expert Analysis
What the evidence tells us.
Evidence published in Nature Reviews Neurology confirms that Africa may now have 2–3 times greater stroke incidence than western Europe and the United States. Critically, many Africans experience strokes during their fourth to sixth decades of life — affecting economically productive individuals during peak years of family responsibility and community contribution.

A multi-centre registry study in Tanzania (2024) covering 1,000 admitted stroke patients found that hypertension was present in 90.1% of cases, making it by far the dominant risk factor. Diabetes and prior stroke were the next most common. These findings underscore the critical importance of preventive screening and blood pressure management — exactly what ANNI's Pillar 2 and Pillar 3 programs target.

The African Stroke Organization (ASO) has identified four core pillars for reducing Africa's stroke burden: research, capacity-building, development of stroke services, and promotion of stroke awareness. ANNI's own five-pillar model is directly aligned with this framework.

ANNI's Response
How ANNI is responding to the stroke burden.
Pillar 1 · Awareness
Delivers public education on stroke warning signs such as FAST symptoms, adapted for African languages and community settings to improve early recognition.
Pillar 2 · Screening
Focuses on blood pressure and diabetes screening, addressing the key modifiable risk factors driving stroke burden across African populations.
Pillar 4 · Research Hub
Builds stroke patient registries to generate African-specific data on incidence, outcomes, and treatment gaps for evidence-based policymaking.
