Concussion (cont.)
IN THIS ARTICLE
Outlook
A person with a single, isolated concussion generally has a very good outcome with few long-term side effects.
Short-term side effects
- Postconcussive syndrome: The main symptom of postconcussive syndrome is persistent headache for one to two weeks, lasting up to months after the injury. Anywhere from 20-90% of patients develop at least one symptom of postconcussive syndrome within the first month following injury, and about 40% have at least three symptoms by three months post-injury.
- Postconcussive syndrome is more common after a serious concussion than after a mild one.
- Symptoms usually are relieved with mild pain relievers such as acetaminophen (Tylenol) or ibuprofen (Motrin, Advil).
- Sometimes people with postconcussive syndrome will have dizziness, difficulty concentrating, or problems doing certain types of activities such as reading.
- Nausea and vomiting may occur.
- Postconcussive syndrome usually goes away on its own with time. Some people may have symptoms that do not go away, even after months. In this situation, contact
a doctor. Sometimes tests (such as an
MRI or cognitive
function testing) or consultations with a neurologist can better assess this problem.
Long-term side effects
- Concussions are known to be cumulative. That is, each time you have a
concussion it is easier to get another concussion in the future.
- Repeated concussions can lead to long-term memory loss, psychiatric
disorders, and other neurologic problems.
- If you have had a number of concussions, your physician likely will advise you to avoid the activities that may put you at risk for future head injuries and to discontinue contact sports. Professional athletes are particularly prone to the effects of cumulative concussions.
