Information for Patients


Also called: Brain concussion

A concussion is a type of brain injury. It's the most minor form. Technically, a concussion is a short loss of normal brain function in response to a head injury. But people often use it to describe any minor injury to the head or brain.

Concussions are a common type of sports injury. You can also have one if you suffer a blow to the head or hit your head after a fall.

Symptoms of a concussion may not start right away; they may start days or weeks after the injury. Symptoms may include a headache or neck pain. You may also have nausea, ringing in your ears, dizziness, or tiredness. You may feel dazed or not your normal self for several days or weeks after the injury. Consult your health care professional if any of your symptoms get worse, or if you have more serious symptoms such as

  • Seizures
  • Trouble walking or sleeping
  • Weakness, numbness, or decreased coordination
  • Repeated vomiting or nausea
  • Confusion
  • Slurred speech

Doctors use a neurologic exam and imaging tests to diagnose a concussion. Most people recover fully after a concussion, but it can take some time. Rest is very important after a concussion because it helps the brain to heal.

Traumatic Brain Injury

Also called: Acquired brain injury, TBI

Traumatic brain injury (TBI) happens when a bump, blow, jolt, or other head injury causes damage to the brain. Every year, millions of people in the U.S. suffer brain injuries. More than half are bad enough that people must go to the hospital. The worst injuries can lead to permanent brain damage or death. Half of all TBIs are from motor vehicle accidents. Military personnel in combat zones are also at risk.

Symptoms of a TBI may not appear until days or weeks following the injury. A concussion is the mildest type. It can cause a headache or neck pain, nausea, ringing in the ears, dizziness, and tiredness. People with a moderate or severe TBI may have those, plus other symptoms:

  • A headache that gets worse or does not go away
  • Repeated vomiting or nausea
  • Convulsions or seizures
  • Inability to awaken from sleep
  • Slurred speech
  • Weakness or numbness in the arms and legs
  • Dilated eye pupils

Health care professionals use a neurological exam and imaging tests to assess TBI. Serious traumatic brain injuries need emergency treatment. Treatment and outcome depend on how severe the injury is. TBI can cause a wide range of changes affecting thinking, sensation, language, or emotions. TBI can be associated with post-traumatic stress disorder. People with severe injuries usually need rehabilitation.
