youngest age to get dementia
For information about Memory Disorder Clinics and the Florida Brain Bank, see Clinical Evaluation and Research. It is very rare to show signs of dementia before age 40, however the youngest person ever diagnosed with Alzheimerâs was 27 years of age. Alzheimerâs and Downâs Syndrome are both on chromosome 21, and patients who have Downâs Syndrome invariably develop Alzheimerâs if they live long enough.
