Most people with a concussion get better within one to four weeks. Recovery varies from person to person, and some people have symptoms that last longer and need more support.
There is no test that gives an exact date. Recovery is judged by how your symptoms respond as you gradually return to school, work and exercise.
What can affect recovery time
- Previous concussions
- How severe your symptoms are in the first days
- A history of migraines, or of anxiety or depression
- Going back to full activity too soon, or resting completely for too long
- Neck injury, dizziness or vision problems that came with the concussion
- Age: children and teens can take longer than adults
What helps
- A short period of relative rest in the first 24 to 48 hours, with light daily activities that do not make symptoms worse
- A gradual, step-by-step return to school or work, then to exercise and sport
- Good sleep, regular meals and limiting screens early on if they aggravate symptoms
- An early assessment, so you have a plan from the start
What slows it down
- Playing through symptoms
- A second hit before the first concussion has healed
- Skipping steps in the return-to-sport process
- Alcohol or recreational drugs during recovery
If symptoms last longer than four weeks
Symptoms that continue beyond about four weeks are often called persistent symptoms or post-concussion syndrome. This does not mean you will not recover. It does mean you should be assessed for treatable contributors such as neck problems, balance and visual issues, and exercise tolerance. See your physician or nurse practitioner, and ask about targeted rehabilitation.
When it is urgent
Go to emergency if symptoms suddenly get worse: a severe or worsening headache, repeated vomiting, a seizure, increasing confusion, or weakness or numbness in the arms or legs.
