A doctor should check anyone who has a head injury, especially if the person lost consciousness or showed a change in thinking, such as confusion or memory loss. A doctor usually will want to know:
The doctor will do a thorough physical and neurological exam. The doctor will check your blood pressure, pulse, vision, the way your eyes respond to light, reflexes and balance, and your ability to answer questions and remember things. If a doctor sees you immediately after a head injury, the examination may be repeated over several hours to make sure you are not getting worse.
If you have mild symptoms, are awake and alert, and have a normal examination, your doctor may just monitor you without doing any more tests. This monitoring can be done at home if you have had a very minor injury. If your symptoms are serious or your neurological exam is abnormal, you will likely need a CT scan of your brain to look for signs of a more serious head injury.
If you are sent home, have someone stay with you for the first 24 to 48 hours because symptoms can become worse quickly or you could lose consciousness if your injury is more serious than your doctor suspected.
