Dementia is emerging as a significant public health issue in Africa, currently affecting approximately 1.9 million people across the continent. This number is projected to increase substantially due to population growth and rising life expectancy. As more Africans live longer, the prevalence of dementia is expected to rise, posing a serious challenge to health systems that are already under strain. The condition impacts not only health but also imposes a considerable economic burden, with costs estimated at US$15.6 billion annually in the African region. This financial strain is largely borne by unpaid caregivers, most of whom are women, who dedicate their time and resources to caring for affected family members.
The majority of this caregiving occurs within the home, as institutional care options are limited across the continent. Unlike in high-income countries where professional care facilities are more common, dementia care in Africa is overwhelmingly provided by spouses, daughters, and daughters-in-law. This invisible workforce receives little training, minimal respite, and almost no financial support. Studies consistently show that caregiver burnout is among the biggest determinants of poor outcomes for people living with dementia. As dementia cases rise, these caregivers face mounting challenges in providing the necessary support, and the condition's effects extend well beyond individual families to the broader socio-economic fabric of African societies.
Globally, more than 55 million people live with dementia, and the World Health Organization projects that number will triple by 2050, with the fastest growth occurring in low- and middle-income countries. Africa's comparatively young population has masked the issue, but improving survival rates and urbanisation are steadily increasing the number of older people at risk. The continent's health systems must adapt to meet the growing demand for specialised care. Health experts argue that priorities should include training primary health workers to recognise and manage dementia, integrating care into existing chronic-disease programmes, supporting caregiver networks, and tackling stigma, which remains one of the biggest barriers to early diagnosis.
Community-based models, built around existing family and community structures, are widely seen as the most realistic path for the continent. These models leverage the strengths of local communities and provide a culturally sensitive approach to care. By focusing on community involvement and support, African countries can develop sustainable strategies to address the rising tide of dementia and ease the burden on families and health systems alike.
