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.

This is a type of dementia that, like Alzheimerâs disease, causes loss of memory and cognitive abilities and most commonly affects patients over the age of 60. But unlike Alzheimerâs where the symptoms come on gradually, the symptoms of vascular dementia may come on more quickly, with memory loss being one of the last symptoms to appear.
