how long does a concussion last for
In general, for most people, symptoms of post-concussion syndrome only last for up to a few weeks. But for some people, the symptoms last longer and can last for three to six months or (rarely) a year or more. The exact reason why some people develop post-concussion syndrome after a blow to the head is not clear.
The researchers used a concussion-symptom scale and found that patients who engaged in the most mental activity took about 100 days to completely recover, having no headaches, dizziness or blurred vision. For those who gave their brains time to heal, recovery time was cut to an average of 43 days, the study found. Study co-author Michael Collins is one of the developers and owners of the company that created and sells the concussion-assessment tool used in the study.
