What are the warning signs for concussion?

CONCUSSION: Headache, dizziness, nausea, vomiting, loss of memory, difficulty concentrating, sleep disturbances, and unsteady gait.

Concussion: Concussions typically can occur after a head injury. It doesn't have to be a severe head injury or have loss of consciousness. It depends on the severity of the injury. The symptoms can include headache, dizziness, vision change (blurred vision/ double vision), nausea/vomiting. If your symptoms or headache are severe, or if you have a loss of consciousness, you should get evaluated immediately

Definition: A concussion by definition is a brief brain injury resulting in loss of consciousness, loss of memory or a combination of both. Persistent symptoms following the event may suggest additional impact on brain function and needs to be addressed.
