How to Say It: Am-ne-ze-uh
by Cynthia M. Johnson, MA
Amnesia is when a person cannot recall new information or past events. It may go away in a short time or be lasting.
Most memory problems are caused by damage to the brain. It may be due to an accident, an illness like a brain infection, stroke, or certain medicines. Sometimes the cause is not known.
Rarely, an emotional event can cause a problem called dissociative amnesia.
Things that may raise the risk are:
A person may have:
You will be asked about your symptoms and health history. The doctor will ask about your memory loss and when it started. A loved one or family member may answer these questions if the person cannot.
These tests may be done to look for a cause:
Any cause will need to be treated. The problem may go away on its own. A therapist or support group may be needed for those whose amnesia does not go away.
There are no current guidelines to prevent this problem.
