Chronic Traumatic Encephalopathy


Chronic traumatic encephalopathy (CTE) is permanent brain damage caused by repeated traumatic brain injuries, such as concussions. Encephalopathy is a term used to describe brain disease or brain damage. A concussion is an injury that causes the brain to hit the skull. After several concussions, certain proteins may start to replace healthy brain tissue. The proteins prevent the brain from working properly.


Call 911 or have someone else call for any of the following:

  • You want to harm yourself or another person.
  • You cannot be woken.
  • You have a seizure.

Seek care immediately if:

  • You have another head injury.

Contact your healthcare provider if:

  • You have new or worsening symptoms.
  • You have trouble sleeping or doing your daily activities.
  • You have questions or concerns about your condition or care.

Manage CTE:

CTE cannot be cured, but the symptoms can be managed:

  • Create routines. Create a schedule for doing daily activities. CTE symptoms are often worse at night. Go to bed and get up in the morning at the same times every day. Talk to your healthcare provider if you have trouble going to sleep or staying asleep.
  • Go to physical, occupational, or emotional therapy as directed. A cognitive behavioral therapist teaches you skills to help with any thinking and behavior problems you may have. A physical therapist can help you with balance, coordination, and muscle control. An occupational therapist can help you learn ways to do your daily activities. For example, you may create a daily activity calendar. Emotional therapy includes talking with a therapist alone or with family members about your symptoms.
  • Ask for support and help. Explain your symptoms to others. Ask them to be patient and to repeat information if needed. A calm, supportive environment can help prevent bursts of anger or other mood problems.
  • Exercise as directed. Exercise can help prevent mood swings. Exercise also helps with muscle coordination and motor skills. You may also sleep more easily with regular exercise. Talk to your healthcare provider about the best exercises for you. A stationary bicycle or exercises done in a chair may be safer if you have trouble walking.
  • Keep your thinking skills active. Do activities that make you think. Some examples are crossword puzzles, learning to read music, and solving jigsaw puzzles.
  • Eat a variety of healthy foods. Healthy foods include fruits, vegetables, whole-grain breads, low-fat dairy products, beans, lean meats, and fish. Healthy foods can help keep your brain healthy.
  • Limit or do not drink alcohol as directed. Alcohol can make your symptoms worse and cause more brain damage. Ask your healthcare provider if it is safe for you to drink alcohol.
  • Do not smoke. Nicotine and other chemicals in cigarettes and cigars can cause blood vessel and brain damage. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
