Symptoms of a concussion can include confusion, dizziness, blurred vision, headache, difficulty concentrating, altered sleep patterns, and, in some severe cases, loss of consciousness. Usually, the brain resumes normal function within 7 to 10 days after a concussion. However, repeated head injuries can cause chronic traumatic encephalopathy (CTE), a neurodegenerative disorder that involves memory loss, depression and suicidal impulses, and eventually dementia.
