What is a concussion?

A concussion is a type of traumatic brain injury (TBI). It is caused by a blow or jolt to the head that disrupts the brain's normal function. Concussions can range from mild to severe, and symptoms can include headache, nausea, vomiting, dizziness, confusion, and memory loss. In some cases, concussions can also lead to long-term problems, such as chronic pain, depression, and anxiety.

Concussions are a common injury, especially in contact sports such as football and hockey. They can also occur in other activities, such as car accidents, falls, and assaults.

If you think you may have a concussion, it is important to see a doctor right away. Early diagnosis and treatment can help to prevent serious complications.
