What Is a Concussion?
A concussion is a type of mild traumatic brain injury (TBI) caused by a blow to the head or body that causes the brain to move quickly inside the skull.
This sudden movement can temporarily disrupt how the brain works.
Common causes include:
- Sports collisions
- Falls
- Car accidents
- Hitting your head on a hard surface
- Sudden whiplash-type movements
Unlike severe brain injuries, concussions often don’t show up on CT scans or MRIs. That’s why doctors rely heavily on symptoms and clinical exams to identify them.
Common concussion symptoms
Symptoms may appear immediately or hours later and can include:

Sleep symptoms

Because symptoms vary from person to person, many people look for a free concussion test online to help determine whether their symptoms are consistent with a concussion.
