Dementia is growing in Africa and health systems face a rising challenge. In Sub‑Saharan Africa there were more than two million people with dementia in 2015, and estimates expect nearly eight million by 2050. Globally, the World Health Organization says about 55 million people live with dementia and about 10 million new cases appear each year.
Researchers at a conference in Nairobi highlighted genetic research to fill knowledge gaps. A 2023 study found that more than a third of people of African ancestry carried a genetic risk factor linked to Parkinson’s, which can be a precursor to dementia. Scientists hope similar studies will help understand Alzheimer’s and other dementias.
Stigma remains common, but Kenyan health workers have engaged traditional healers and clergy to build dialogue and referrals to clinicians. In Tanzania, a team led by Jim Todd is testing a digital voice tool and comparing voice features with blood biomarkers, with plans to collect more voice data over six months to a year.
Experts urged collaboration among researchers, the private sector and governments, and called for national dementia programmes and combined medical and community approaches.
