A concussion is a brain injury. It can’t be seen on X-rays, CT scans or MRIs. It may affect the way a person thinks, feels and acts.
Any blow to the head, face or neck may cause a concussion. A concussion may also be caused by a blow to the body if the force of the blow causes the brain to move around inside the skull. A concussion can happen to anyone – anywhere – including:
- at home, school or your workplace
- following a car, bike or pedestrian accident
- from participating in games, sports or other physical activity
A concussion is a serious injury. While the effects are typically short-term, a concussion can lead to long-lasting symptoms and even long-term effects.
There are many signs and symptoms of a concussion to look out for, including:
- ringing in the ears
- memory loss
- light sensitivity
If you notice signs of a concussion in others, or experience any of these symptoms yourself, consult with a physician or nurse practitioner.
Know the risks
You can get a concussion even if you don’t black out or lose consciousness.
Slips and falls can also increase concussion risk, especially in:
- young children
- senior citizens
Take time to heal
It is important to take time and heal if you have a concussion.
In some cases, concussions or repeat concussions can result in:
- swelling of the brain
- permanent brain damage
