average time dizziness lasts after concussion
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.
By Mayo Clinic Staff. Post-concussion syndrome is a complex disorder in which various symptoms â such as headaches and dizziness â last for weeks and sometimes months after the injury that caused the concussion. Concussion is a mild traumatic brain injury, usually occurring after a blow to the head. Loss of consciousness isn't required for a diagnosis of concussion or post-concussion syndrome. In fact, the risk of post-concussion syndrome doesn't appear to be associated with the severity of the initial injury.
