A concussion is a type of traumatic brain injury that can affect the way your brain works. In most cases, concussions resolve within hours or days of the injury. Postconcussion syndrome (PCS) refers to continued symptoms of mild traumatic brain injury. It often resolves within a month, but sometimes the symptoms persist for much longer.
PCS symptoms vary from person-to-person. PCS may cause:
- Balance problems
- Vision problems
- Sensitivity to noise and/or light
- Mood swings
- Memory problems
- Concentration problems
- Trouble sleeping
The brain damage caused by a mild brain injury is so slight that most tests cannot detect it. Your doctor may perform tests that include:
- Memory and attention tests
- Sports concussion assessment tool
- Electroencephalogram (EEG) to look for abnormal brain electrical activity
Your doctor may also take pictures of your internal body structures with:
- CT scans
- MRI scans
Treatment depends on the severity and length of time of your symptoms.
Your doctor may recommend:
- Pain relievers
- Nerve blocks
Your doctor may refer you to a therapist to talk about your problems related to PCS and to learn how to cope with those problems.
Neurotherapy, also called biofeedback, is a painless treatment that uses computers to help you learn how to modify your brainwaves to improve attention and memory.
In some cases, a collection of blood in an area of bruising on the brain may require surgery, which may help resolve or improve symptoms.
