Concussion: Symptoms & Signs

A concussion is a form of minor brain trauma in which the function of the brain becomes altered but no abnormalities can be detected by imaging tests such as CT scans. Symptoms of a concussion are typically short-lived and go away on their own. The symptoms may be obvious or may be so subtle that the affected person does not realize they have suffered a concussion. Some of the more common symptoms of concussion include

• headache,
• feeling foggy, or that one's thinking is slowed or altered,
• nausea,
• lightheadedness,
• dizziness,
• irritability or emotional changes,
• problems concentrating or remembering new information.

Sometimes people with a concussion will lose consciousness (pass out), but this does not happen in most cases. Not all symptoms of concussion will occur in every case; sometimes the symptoms differ depending on the location and extent of the injury. For example, some people suffering from a concussion may sleep excessively while others have insomnia. Symptoms of concussion can last for days, weeks, or occasionally even longer.
