Reporting of early symptoms of dementia varies across ethnic groups, study finds

A new study found that people from minority ethnic groups are more likely to report non-cognitive symptoms, such as pain and dizziness, before receiving a dementia diagnosis. This can lead to delays in diagnosis and impact health inequalities. The research aims to improve culturally fair recognition of possible dementia in primary care.
