A concussion is a mild traumatic brain injury that results from a bump, violent jolt or blow to your head that disrupts normal brain function. A concussion can also be caused by a hit to your body that is strong enough to cause your head to forcefully jerk backwards, forwards or to the side.

Concussions stretch and bruise nerves and blood vessels and cause chemical changes in your brain that result in a temporary loss of normal brain function. A single concussion usually doesn’t cause permanent damage to your brain. Multiple concussions over a lifetime may result in structural changes in your brain.

Concussions are not usually life-threatening. However, the effects from a concussion can be serious and last for days, weeks or even longer.

A concussion is a mild traumatic brain injury caused by a bump, violent jolt or blow to your head. Anyone from infants to the elderly can get a concussion. Headache is the most common symptom. Most symptoms resolve within 14 to 21 days. Although recovery plans are unique to each person, all involve mental and physical rest and a gradual return to activity.
Consider all head injuries as a potentially serious event. If you have a “gut instinct” that something more might be wrong or worry that a fall on the head or blow to the head needs to be checked out, do it. Call your doctor or go to the emergency room.
Rest. Rest is one of the most important treatments for a concussion because it helps the brain to heal. Rest nearly completely for the first few days after a head injury, then slowly begin to “exercise your brain.” The unused, “stagnant” brain remains stagnant if not used and lengthens recovery. But too much use overstimulates the brain and can cause symptoms to return or worsen. Take a slow approach. Identify and avoid or limit your time doing things that cause symptoms. For example, if symptoms increase with the bright light of a computer or smartphone, adjust the brightness setting, wear sunglasses or strictly limit your time on these devices. Ease into normal activities slowly, not all at once.
Don’t drink alcohol without your doctor's okay. Alcohol and other drugs may slow recovery and increase the chance for further injury.
Don’t drive until cleared by your doctor. Your reaction time could be slower until you fully recover.
