Dementia in Ghana: Study finds 23.4% of adults over 40 at risk as experts call for national care policy

Nearly one in four adults aged 40 and above in parts of Ghana’s Ashanti Region are at risk of developing dementia, a finding experts say highlights a growing public health challenge and exposes gaps in the country’s care system. The figure of 23.4% comes from a cross-sectional study involving more than 800 participants conducted between 2023 and 2025 as part of a UK-Ghana research collaboration on non-communicable diseases.
