"Anyone who has had a blow to the head or body that results in symptoms of TBI—even temporarily—should get prompt medical attention," says Dr. Williams.

Even if you don't have symptoms, you should see a doctor if your head got hit with force.

"Because separate areas of the brain are connected and work together to perform complex tasks, people can end up with issues in parts of the brain far from the area of impact," Dr. Williams explains. 

When you see a doctor about a brain injury, a thorough neurological history and exam will be performed.

Dr. Williams says it should include details of the injury, such as how it happened, if you lost consciousness or had amnesia, and if you vomited or had any other symptoms.

You should be screened for problems with orientation, memory, concentration, mental processing, eye movements and balance, as well as coordination, motor, and sensory issues. In some cases, the doctor will recommend more tests, such as imaging or electrical testing.

Your personal and family history should be explored too, because some people may be predisposed to longer-lasting symptoms.

The vast majority of people with TBI will recover in 10-14 days. 

"Only 15% of patients have lasting symptoms," says Dr. Williams, "and most of them usually had some predisposing factors. But even they can get better with the right intervention."
