What kind of doctor treats Traumatic Brain Injury?
A neurologist specializes in the brain, spinal cord, and nerves and usually manages traumatic brain injury care. In emergencies, emergency medicine doctors and trauma surgeons handle the first treatment. Some patients also work with physiatrists, who focus on rehabilitation. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
A traumatic brain injury is damage to the brain caused by a sudden hit, bump, or jolt to the head. It can be mild, like a brief shake-up of how the brain works, or severe, causing long-lasting problems. Doctors often call a mild traumatic brain injury a concussion.
Symptoms
Symptoms can show up right away or appear hours or days later. A person might have a headache, feel dizzy, or feel confused. Some people become sensitive to light and noise. In serious injuries, a person may have repeated vomiting, weak arms or legs, slurred speech, or a seizure. These serious signs need emergency care right away.
Causes and who gets it
The most common causes are falls, car crashes, sports injuries, and being struck by or hitting an object. Falls are the leading cause, especially in young children and adults over 65. Children, teens, and older adults tend to have the hardest recoveries.
How doctors diagnose it
A doctor starts by asking what happened and checking how the person thinks, moves, and feels. Imaging tests such as a CT scan or MRI can show bleeding, bruising, or swelling in the brain.
Treatment
Treatment depends on how bad the injury is. For a mild injury, the main plan is rest and a slow return to normal activity. Moderate to severe injuries often need hospital care, and surgery may be needed to repair damage or relieve pressure. Rehabilitation can help many people improve over time.
When to see a doctor
Anyone with a hard hit to the head who feels confused, loses consciousness, vomits, or has a worsening headache should be seen by a doctor. Emergency signs include seizures, clear fluid draining from the nose or ears, extreme sleepiness, or weakness on one side of the body.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either type can evaluate mild head injuries, order imaging, and guide the return to activity, referring moderate or severe cases to a specialist.
Common questions
How long does recovery take?
Most people with a mild injury feel better within days to weeks. Recovery from a more severe injury can take months or longer, and results differ from person to person.
Can I sleep after a hit to the head?
For a mild injury with no warning signs, sleep is usually fine and often helps. A doctor may advise a family member to check on the person at first after a stronger injury.
Can a second head injury be worse?
Yes. Getting another hit before the brain has healed can make symptoms worse and last longer. This is one reason doctors recommend a gradual return to sports and other activities.
Do I need a scan after every bump on the head?
No. Doctors use rules based on age, symptoms, and how the injury happened to decide who needs imaging. Many mild head injuries do not need a scan at all.
