What is Concussion?
Updated January 24, 2026
A mild traumatic brain injury caused by a blow or jolt to the head that temporarily affects brain function, causing symptoms like headache, confusion, and memory problems.
Understanding Concussion
Concussions may not show up on standard imaging like CT scans or MRIs. Symptoms can be immediate or delayed and typically resolve within weeks, though some people develop post-concussion syndrome with persistent symptoms. Multiple concussions can have cumulative effects.
Examples
- 1Concussion from hitting head on steering wheel
- 2Post-concussion syndrome lasting months after accident
- 3Second impact syndrome from repeated head injuries
