How is it diagnosed?
First a doctor will examine you. The doctor will want information from people who were there when you were injured. This is very important, especially if you're confused or if you lost your memory. The doctor will test your strength, sensation, balance, reflexes and memory. In more serious cases, your doctor will want to get special x-rays of your head, called computed tomographic (CT) scans or magnetic resonance images (MRI).
