After a concussion (a mild traumatic brain injury), some people have symptoms that last longer than expected. While most concussion symptoms go away within three months, they can sometimes last for a year or more.
These symptoms may include:
- Dizziness
- Headaches
- Memory loss
- Problems with concentration
- Irritability or bad mood
- Fatigue
- Sleep issues
- Blurry vision
- Sensitivity to noise or light
