By studying 13,000 people during midlife (40’s and 50’s) to their 80’s, those who did have symptoms of depression were 20% more likely to have dementia in old age. If they received a depression diagnosis later in life, they were at a 70% risk of dementia. Interestingly, timing played a role in the type of dementia. Depression diagnosed in midlife was linked to vascular dementia while later in life depression it’s linked to Alzheimer’s.
