Concussion

A concussion is a mild form of a traumatic brain injury (TBI) that results from the brain can be caused by a bump, blow, or jolt to the head. Concussions can also result from violent or sudden shaking, or whiplash movements.

Symptoms of a concussion may include headache, neck pain, nausea, ringing in the ears, dizziness, vision problems, feeling dazed, and memory problems. Sometimes loss of consciousness occurs when the injury occurs, but not all concussions cause loss of consciousness. Symptoms of a concussion typically resolve within 7 to 10 days for most people.

When someone suffers a blow to the head, or a sudden change in direction of the head (such as a whiplash injury), the brain may strike against the inside of the skull. This can cause injury to the brain, and produce concussion symptoms.

Treatment for concussion is primarily physical and mental rest. Acetaminophen may be used for headache pain relief. NSAIDs are not recommended because of the small risk of bleeding in the brain after a traumatic brain injury.

Concussions can occur from a bump, blow, or jolt to the head. Concussions commonly are a result of a sports injury.

See a doctor after any head injury with headache, confusion, dizziness, or nausea. Seek emergency care for repeated vomiting, worsening headache, seizures, slurred speech, weakness, unequal pupils, or trouble staying awake.
