It is very rare to show signs of dementia before age 40, however the youngest person ever diagnosed with Alzheimerâs was 27 years of age. Alzheimerâs and Downâs Syndrome are both on chromosome 21, and patients who have Downâs Syndrome invariably develop Alzheimerâs if they live long enough.
Many people assume that Alzheimer's disease and other causes of dementia only affect older people. In fact, about 1 person in every 1000 below the age of 65 develops dementia. While rare, it can affect people in their 40's and 50's. Any dementia beginning before the age of 65 is known as early onset dementia. Each person's experience of dementia is unique. Although the symptoms of dementia are similar whatever a person's age, younger people with dementia have different needs.
