A concussion is an injury to your brain. The brain does not work right for a while after a concussion. You may have problems with things like memory, balance, concentration, judgement, and coordination. Your brain will need time to heal after a concussion.

A concussion is caused by a sudden, violent jolt to the brain. It may be caused by:

A concussion is an injury to your brain. The brain does not work right for a while after a concussion. You may have problems with things like memory, balance, concentration, judgement, and coordination.
Your brain will need time to heal after a concussion. Most will have a full recovery with the proper rest and monitoring.
The doctor will ask you about your symptoms and how the injury occurred. The doctor may also ask others who witnessed the accident to describe what happened and how you reacted. A physical exam will be done. It will often include brief tests for strength, sensation, balance, reflexes, and memory.
Imaging tests evaluate the head, brain, and surrounding structures for injury and/or damage. These may include:
- CT scan
- MRI scan
To prevent vehicle accidents and head injuries associated with car accidents:
- Do not drink alcohol and drive.
- Do not take medicines that may make you sleepy, especially when driving or using heavy equipment.
- Obey speed limits and other driving laws.
- In vehicles, always use seatbelts and child safety seats. Only use child safety seats when traveling. Do not use them outside of the vehicle.
To prevent concussions with recreational activities and sports:
Wear a helmet when:
- Riding a bike or motorcycle
- Playing a contact sport like football or hockey
- Using skates, scooters, and skateboards
- Catching, batting, or running bases in baseball or softball
- Riding a horse
- Skiing or snowboarding
- Wear mouth guards, face guards, pads, and other safety gear while playing sports.
To prevent accidents at home that can lead to concussions:
- Make sure your child's play surface is soft and free of rocks, holes, and debris.
- Use handrails when walking up and down stairs—teach your child to do so
- Have safety gates by stairs and safety guards by windows
- Use grab bars in the bathroom
- Place non-slip mats in the bathroom
- Keep walkways clear to avoid tripping
- Make sure rooms and hallways are well-lit

- Blurred vision or eyes that tire easily
- Loss of sense of taste or smell
- Ringing in the ears or trouble hearing
- Feeling sad, anxious, or listless
