Can a brain injury lead to Alzheimer’s?

Karns & Kerrison

The brain is a very complex thing. Even those who specialize in studying and working with it in Rhode Island are not completely aware of everything about it. It is like the unknown frontier of the body. There is still much to learn. This makes it difficult when there are diseases, such as Alzheimer's, that we want to know more about. That is why there are always studies to try to find more information.

According to the Alzheimer's Association, there have been some studies done to see if brain injuries can increase the likelihood of someone getting Alzheimer's. While there have not been enough studies done to make conclusive conclusions, preliminary data suggests there is a link between brain injuries and an increased risk of developing Alzheimer's.

Particularly, the studies have shown that repeat injuries or moderate or severe brain injuries may increase your chances of Alzheimer's. Some studies have looked at certain groups of people who may be more likely to suffer repeat brain injuries, such as soldiers and athletes. The findings show the risks of these groups is much higher than normal of getting Alzheimer's.

There has also been data collected that show brain injuries can cause protein abnormalities that are like those seen in Alzheimer's patients. This could be another link to prove brain injuries could lead to Alzheimer's. 

None of the studies are conclusive, though, which is important to understand. In addition, it is believed that a mild injury or even a one-time injury may not increase your chances of developing the disease. This information is for education and is not legal advice.
