Treatment

The only "tried and true" method of treatment after a concussion is rest. A person with a concussion should:

Avoid loud environments (ie. crowds, classrooms)
Avoid bright lights and stimulation
Avoid electronic screens and print
Avoid stimulation of the brain (ie. homework, puzzles, games, etc.)
Sleep as much as the body needs
Drink plenty of water and eat a healthy diet
Avoid alcohol or unprescribed drugs
Use acetominophen to control headache
Avoid ibuprofen, aspirin, Advil, and motrin, as these may increase chances of intercranial bleeding

Return to ADLs and Participation

Patient can return to activities of daily living as tolerated, and should not try to push through discomfort.

Patient can return to play:

After coming close to their pre-injury scores on the IMPACT test
Report no symptoms related to the concussion and have not developed any new ones
Complete a return to play protocol that gradually increases the heart rate and showing no symptoms.
Once cleared by a physician, if the injury was severe enough to require hospitalization
