Concussion | Diagnosis & Tests


How is a concussion diagnosed?

You should contact your doctor if any of the signs or symptoms are noticeable following a head injury. If the symptoms are severe, getting worse over time, or if you have specific concerns, you should transport the injured person to an emergency room. It is particularly concerning if the person cannot be awakened, is having convulsions or seizures, or cannot recognize people or places.

The doctor will want information from people who were present when the injury occurred. The doctor may test strength, senses, balance, reflexes, and memory. In more serious cases, the doctor may want specific medical tests completed, such as computed tomographic (CT) scans to look for more severe injuries.
