Doctors can do more for a concussion than most people expect. While there’s no single pill or procedure that “fixes” one, concussion care in 2025 involves structured assessment, guided recovery timelines, targeted therapies for specific symptoms, and a stepwise plan for getting back to normal life. The old advice to sit in a dark room for days has been replaced by a much more active, individualized approach.
How Doctors Diagnose a Concussion
A concussion is diagnosed clinically, meaning through observation and testing rather than a brain scan. Doctors use standardized tools like the Sport Concussion Assessment Tool (SCAT6), which walks through a series of checks: observable signs like confusion or balance problems, a symptom checklist covering 22 items (headache, fogginess, light sensitivity, trouble sleeping, and others), orientation questions, memory recall of a 10-word list, and concentration tasks like reciting digits backward.
The physical exam includes coordination checks such as finger-to-nose testing, eye movement tracking to look for double vision or abnormal gaze, and a cervical spine assessment to rule out neck injury. These aren’t just formalities. They create a baseline that doctors compare against later to measure your recovery.
CT scans are not routine for every concussion. Doctors order imaging when specific red flags are present: a consciousness score that hasn’t returned to normal within two hours, two or more episodes of vomiting, signs of a skull fracture, amnesia lasting more than 30 minutes before the injury, age 65 or older, or a dangerous mechanism of injury like a car crash or a fall from height. The scan’s purpose is to rule out bleeding or structural damage, not to see the concussion itself, which doesn’t show up on imaging.
The First 48 Hours: Relative Rest, Not Total Rest
The biggest shift in concussion management is the move away from “cocooning,” where patients were told to lie in a dark room and avoid all stimulation for days. Current evidence is clear: strict or prolonged rest does not speed recovery and may actually slow it down.
What doctors recommend instead is relative rest for the first 48 hours. That means scaling back your usual routine, not eliminating all activity. You can do light daily tasks, take short walks, and have conversations. The main thing to limit during this window is screen time, since phones, computers, and TVs tend to worsen symptoms like headache and eye strain early on. Light physical activity can start as soon as one day after injury, and prescribed aerobic exercise can begin as early as two days out, as long as symptoms don’t significantly worsen.
Managing Headaches and Sleep Problems
Post-concussion headaches are the most common lingering symptom, and doctors treat them based on the type of headache you’re experiencing. Over-the-counter anti-inflammatory pain relievers are typically the first step. If headaches persist or take on migraine-like qualities, doctors may prescribe preventive medications, often drugs originally developed for other conditions like blood pressure regulation, mood disorders, or nerve pain. These work by calming the overactive signaling that drives recurring headaches.
One important detail: some post-injury headaches actually originate from a neck strain (whiplash) that happened during the same impact. In that case, anti-inflammatory medication combined with physical therapy targeting the neck is more effective than treating the head alone.
Sleep disruption is the other major complaint. Doctors start with sleep hygiene coaching: consistent bed and wake times, limited screens before bed, a cool and dark room. Melatonin is considered safe and effective as a first-line supplement. If insomnia persists, certain low-dose medications that also help with headache prevention can pull double duty, addressing both problems at once. Sedatives like benzodiazepines are specifically avoided because they impair cognition and motor function, which are already compromised after a concussion.
Vestibular and Vision Therapy
If your concussion leaves you with dizziness, balance problems, or a sense that the world is moving when it shouldn’t be, doctors refer you to vestibular rehabilitation therapy. This is a specialized form of physical therapy that retrains your brain’s ability to process balance and spatial information.
Treatment starts with testing to identify your specific deficits, then progresses through targeted exercises. Gaze stabilization, for example, involves focusing on a fixed object while slowly moving your head side to side or up and down. This trains your eyes and inner ear to coordinate properly again. Other exercises challenge your balance in progressively harder positions. Most people notice improvement within a few weeks of consistent work.
Vision problems like difficulty tracking objects, blurred vision, or light sensitivity may prompt a referral to a neuro-optometrist, a specialist who focuses on visual symptoms tied to brain injuries. Treatment might include specific eye exercises or temporary use of tinted lenses to reduce light sensitivity.
Cognitive Rehabilitation
Trouble concentrating, forgetting things mid-sentence, feeling mentally sluggish: these cognitive symptoms are common and usually resolve on their own within weeks to months. But when they linger, a neuropsychologist can run formal testing to pinpoint exactly which areas are affected, whether that’s processing speed, working memory, attention, or reasoning.
Based on those results, targeted cognitive therapy strengthens the specific skills that are lagging. Some people benefit from occupational therapy or speech therapy, depending on which functions are most disrupted. In the meantime, practical strategies like using a notebook, setting phone reminders, and breaking tasks into smaller steps help bridge the gap while the brain heals. Stress management matters here too, since anxiety and pressure measurably worsen cognitive symptoms after a concussion.
The Return-to-Activity Progression
Doctors don’t just clear you and send you back to your life all at once. Recovery follows a structured, stepwise protocol where each stage takes a minimum of 24 hours, and you only advance if symptoms stay manageable.
- Step 1: Return to regular daily activities like school or desk work, with clearance from your doctor to begin the progression.
- Step 2: Light aerobic activity only, such as 5 to 10 minutes on a stationary bike, walking, or light jogging. No weight lifting.
- Step 3: Moderate activity that increases heart rate with body or head movement. Moderate jogging, brief running, and reduced-weight lifting are introduced.
- Step 4: Heavy non-contact activity, including sprinting, full weightlifting routines, and sport-specific drills.
- Step 5: Full practice with contact, in a controlled setting.
- Step 6: Return to competition.
If symptoms flare at any step, you drop back to the previous stage and try again after another 24-hour rest. This same graduated approach applies to returning to work or school, not just sports. The principle is the same: increase demands on the brain slowly and let symptom response guide the pace.
When Symptoms Last Longer Than Expected
Most concussions resolve within two to four weeks. When symptoms persist beyond that window, the condition is called persistent post-concussive symptoms. There’s no single treatment for it. Instead, doctors shift to a multidisciplinary approach, matching each symptom to the right specialist.
Ongoing dizziness goes to a vestibular physical therapist. Vision changes go to a neuro-optometrist or ophthalmologist. Anxiety or mood changes may call for a psychologist. Memory and thinking problems might involve occupational or speech therapy. Persistent headaches get managed with preventive medications tailored to the headache type. The goal is to treat each symptom pathway directly rather than waiting for everything to resolve on its own.
This coordinated care makes a real difference. People with prolonged symptoms who are actively managed by a team tend to recover faster than those who simply rest and hope. If your primary care doctor isn’t comfortable managing complex post-concussion symptoms, asking for a referral to a concussion clinic or sports medicine specialist with brain injury experience is a reasonable next step.
