Chronic traumatic encephalopathy (CTE) is the breakdown of brain cells over time, caused by repeated head injury or blasts from explosions. Head injuries include concussions.

Symptoms of CTE can include depression, aggression, confusion, personality changes, and problems with moving quickly or speaking clearly

CTE is a type of dementia, which is a brain problem that makes it hard to remember, think, and learn.
Symptoms may not start until later in life, sometimes after age 60.
Some people with CTE have mild symptoms in young adulthood that get more severe later in life. .
Doctors suspect CTE in people who have had many episodes of head injuries or exposure to loud explosions and have symptoms of CTE.
There's no test to confirm a CTE diagnosis, but doctors will do brain imaging tests such as CT scan. The imaging tests help doctors see if the person has some other condition with similar symptoms. The only way doctors know for sure a person has CTE is by studying the person's brain after death.
There's no cure for CTE, but the following help:
To help reduce risk of CTE, people who have had a concussion should rest and stay away from athletic activities for a period of time.
Before dementia affects decision making, people with CTE should make as many medical, financial, and legal decisions as possible. This includes choosing someone who can make additional medical decisions on your behalf once you can no longer do so. You should also discuss with your doctor what types of care you will want at the end of your life (living will).

Caring for people with any type of dementia is stressful and demanding. Caregivers may become depressed and exhausted, often not taking care of their own mental and physical health. It's important for caregivers to:
Learn how to meet the needs of people with dementia and what to expect from them
Seek help when needed, such as day-care programs, visits by home nurses, housekeeping help, live-in assistance, counseling, and support groups
Take time to care for themselves, including spending regular time with friends and on hobbies and activities
