Seek emergency care after a head injury if there’s loss of consciousness, repeated vomiting, worsening or severe headache, seizures, confusion, weakness or numbness, slurred speech, unequal pupils, or clear fluid from the nose or ears. Call 911 for these warning signs.
Most concussions heal with time and the right care — but knowing how to support recovery, and when symptoms warrant a neurologist, makes a real difference. A concussion is a mild traumatic brain injury, and it deserves to be taken seriously. Here’s what concussion recovery looks like, and when to see a specialist.
What a concussion is
A concussion is a mild traumatic brain injury caused by a bump, blow, or jolt to the head — or a hit to the body that makes the head move rapidly. It temporarily affects how the brain works. You don’t have to lose consciousness to have a concussion; many people never black out at all.
Normal recovery timeline
Most people recover from a concussion within a couple of weeks, though it varies. Common symptoms include headache, dizziness, nausea, sensitivity to light or noise, trouble concentrating, irritability, and sleep changes. These typically improve gradually — the key is giving your brain time and not rushing back to full activity.
How to support recovery
Early on, balance rest with gentle activity as tolerated. Limit screen time and intense mental or physical exertion at first, then gradually increase activity as symptoms allow. Prioritize sleep, stay hydrated, and avoid alcohol. Crucially, don’t return to sports or risky activity until you’ve been cleared — a second hit before healing can be dangerous.
When to see a neurologist
See a neurologist if symptoms persist beyond a couple of weeks, worsen, or interfere with work, school, or daily life. This may be post-concussion syndrome, where symptoms linger and benefit from specialized care. A neurologist can guide your recovery, manage symptoms, and clear you to return to activity safely.

How it’s evaluated
A neurologist reviews how the injury happened and your symptoms, then performs a neurological exam assessing thinking, balance, coordination, vision, and reflexes. Imaging isn’t usually needed for a straightforward concussion but may be ordered if there are red flags or the picture is unclear.
Treatment and getting back to life
Treatment focuses on managing symptoms and a gradual, guided return to activity — sometimes with targeted therapies for issues like headaches, dizziness, or visual symptoms. With the right plan, most people return to their normal routines. If concussion symptoms are lingering, book an appointment or call (301) 797-7600.
Frequently asked questions
How long does a concussion last?
Most people recover within a couple of weeks, though it varies. Symptoms lasting longer may indicate post-concussion syndrome and warrant a neurologist.
When should I see a doctor for a concussion?
See a neurologist if symptoms persist beyond a couple of weeks, worsen, or interfere with daily life. Seek emergency care for severe warning signs after the injury.
What are post-concussion symptoms?
Lingering headache, dizziness, difficulty concentrating, irritability, sleep changes, and sensitivity to light or noise that continue after the expected recovery window.
Can I return to sports after a concussion?
Only after you’ve been medically cleared. Returning too soon — before the brain has healed — raises the risk of serious complications.
