Concussions are a risk factors for Alzheimer's pathology, especially those which occur after the age of 50. Multiple concussions increase Alzheimer's risk, especially those which involve the loss of consciousness. For example, a person who has been concussed 3 times may have 3 to 4 times the risk of developing Alzheimer's. This, of course, depends on the severity of the concussion

Depending on your age, the standard risk of Alzheimer's can go from around .035% for those in their 30's, 40's and 50's to up to 50% in your mid-80's and later. Risk increases with age, doubling every 5 years after age 65.
