Treatment for a traumatic brain injury depends almost entirely on how severe it is. A mild TBI (concussion) typically resolves with a short period of rest followed by a gradual return to activity, while a moderate or severe TBI requires emergency medical care, possible surgery, and months of rehabilitation. Severity is classified using the Glasgow Coma Scale: scores of 13 to 15 indicate a mild injury, 9 to 12 moderate, and 3 to 8 severe.
Treating a Mild TBI (Concussion)
Most people searching for TBI treatment are dealing with a concussion, and the good news is that strict bed rest in a dark room is no longer the standard recommendation. The CDC advises limiting screen time and mentally or physically demanding activities for the first one to two days, but not lying on the couch or in bed all day. Within two days, you should begin light physical activity like going for walks, even if you still have mild symptoms.
Sleep is important during early recovery, but so is gentle movement. The old “cocoon” approach, where patients isolated themselves in dark, quiet rooms for days or weeks, has been largely abandoned. Light activity helps the brain recover faster than total inactivity does. What you want to avoid during those first few days is anything that significantly spikes your heart rate, requires intense concentration, or risks another blow to the head.
Headaches, fatigue, trouble concentrating, and irritability are all normal in the days and weeks following a concussion. Over-the-counter pain relievers can help with headaches, though you should avoid blood-thinning options like aspirin unless cleared by a doctor. Most concussion symptoms resolve within two to four weeks, though some people experience symptoms for longer.
Returning to Sports and Physical Activity
If you or your child had a concussion during sports, the CDC outlines a six-step return-to-play progression. Each step requires a minimum of 24 hours before moving to the next, and you should only advance if symptoms don’t return at the current level.
- Step 1: Return to regular daily activities like school or work, with medical clearance to begin the progression.
- Step 2: Light aerobic activity only, such as 5 to 10 minutes on a stationary bike or light jogging. No weight lifting.
- Step 3: Moderate activity that increases heart rate with body or head movement, including moderate jogging and reduced-weight lifting.
- Step 4: Heavy non-contact activity like sprinting, high-intensity biking, full weightlifting routines, and sport-specific drills.
- Step 5: Return to practice with full contact in a controlled setting.
- Step 6: Return to competition.
If symptoms come back at any step, drop back to the previous level and wait at least 24 hours before trying again. Rushing this progression is one of the most common mistakes, and it significantly increases the risk of prolonged symptoms or re-injury.
Emergency Treatment for Moderate and Severe TBI
A moderate or severe TBI is a medical emergency. The immediate priority in the hospital is preventing secondary damage to the brain, which means controlling swelling, maintaining oxygen flow, and keeping blood pressure stable. Brain swelling is the most dangerous complication because the skull is a fixed space. As pressure inside the skull (intracranial pressure) rises, it compresses brain tissue and can be fatal.
Current guidelines recommend treating intracranial pressure when it rises above 22 mmHg, because levels above this threshold are associated with increased mortality. Doctors use several tools to bring the pressure down: medications that draw fluid out of brain tissue, draining cerebrospinal fluid through a small catheter, adjusting ventilator settings, and sedation to reduce the brain’s metabolic demand.
Seizure prevention is standard care in the first seven days after a severe TBI. Anti-seizure medications are given during this window because early post-traumatic seizures can worsen brain swelling and cause additional damage. After seven days, the medications are typically stopped unless seizures have actually occurred.
When Surgery Is Needed
Not every TBI requires surgery, but when intracranial pressure stays dangerously elevated despite medication, surgical intervention becomes necessary. The most common procedure is a decompressive craniectomy, where a portion of the skull is temporarily removed to give the swelling brain room to expand without compressing vital structures. Guidelines from major clinical trials defined “refractory” pressure as readings above 20 to 25 mmHg that persist for extended periods despite maximum medical treatment.
The recommended size of the skull opening matters. Research shows that a large opening (at least 12 by 15 centimeters) leads to better survival rates and neurological outcomes than a smaller one. The removed bone flap is preserved, often stored in a medical freezer or implanted temporarily in the patient’s abdomen, and replaced in a second surgery once swelling has resolved, typically weeks to months later. Surgery may also be needed to remove blood clots (hematomas) that form between the skull and brain or within the brain tissue itself.
Nutrition During Acute Recovery
A brain recovering from trauma burns through calories at a remarkable rate. TBI patients need significantly more protein than healthy individuals, roughly 1.5 to 2.0 grams per kilogram of body weight per day, which works out to about 100 to 140 grams of protein daily for a 150-pound person. This protein supports tissue repair and helps the brain rebuild damaged connections.
Feeding typically begins within 24 hours of hospital admission, but starts conservatively at about one-third to two-thirds of the patient’s full caloric needs for the first three to five days. After day six, intake is gradually increased to meet 100% of estimated needs. For family members of someone with a severe TBI, understanding this is helpful: if the medical team seems to be feeding your loved one less than expected in those early days, that is intentional and evidence-based.
Rehabilitation After a TBI
Once a patient is medically stable, rehabilitation becomes the primary treatment. The specific therapies depend on which functions were affected.
Cognitive Rehabilitation
Memory problems, difficulty planning, and trouble staying focused are among the most common lasting effects of moderate to severe TBI. Cognitive rehabilitation uses structured exercises that start simple and get progressively harder. A therapist might begin with basic attention tasks (sorting cards, following two-step instructions) and gradually move toward more complex challenges like managing a simulated schedule or solving multi-step problems. These exercises can be done in a clinical setting or at home using guided activity programs like the one developed by the University of Alabama at Birmingham’s TBI Model System.
Vestibular Rehabilitation for Dizziness and Balance
Dizziness, vertigo, and balance problems are common after head injuries at all severity levels. Vestibular rehabilitation is a specialized form of physical therapy that retrains the brain to process balance signals correctly. The exercises are straightforward but targeted: gaze stabilization involves focusing on an object while slowly turning your head side to side, balance retraining progresses from standing with feet together to standing on one foot, and walking exercises increase in difficulty by adding head movements or obstacles. Most people see meaningful improvement within six to eight weeks of consistent therapy.
Hormonal Problems After TBI
One of the most underdiagnosed consequences of TBI is damage to the pituitary gland, a small structure at the base of the brain that controls hormone production throughout the body. A meta-analysis of 14 studies found that roughly 27.5% of TBI patients develop some form of pituitary dysfunction. The rates vary by severity: about 17% of mild TBI patients, 11% of moderate, and 36% of severe TBI patients are affected.
Symptoms can include persistent fatigue, weight changes, loss of sex drive, mood disturbances, and menstrual irregularities, many of which overlap with other post-TBI symptoms and get attributed to the brain injury itself rather than a treatable hormonal deficiency. British Neurotrauma Group guidance recommends that anyone hospitalized for more than 48 hours following a TBI undergo hormone screening at three to six months post-injury. If you had a significant TBI and are experiencing unexplained fatigue, weight gain, or mood changes months later, hormonal testing is worth requesting. These deficiencies are treatable with hormone replacement once identified.
