A concussion is a type of traumatic brain injury that occurs when the brain is jolted or shaken inside the skull, typically due to a blow to the head or a sudden movement of the head and body. This can lead to a temporary disruption in normal brain function, resulting in symptoms such as headache, confusion, dizziness, nausea, balance problems, and memory disturbances. Concussions are often associated with sports injuries but can occur in various situations, including falls and car accidents.
