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.
