A concussion is a traumatic brain injury (TBI) caused by a direct blow to the head, face, neck, or elsewhere on the body.
Concussions are sometimes described as mild TBIs because they usually do not result in life-threatening symptoms. However, concussions can be associated with extremely serious effects in some cases.
Concussions typically cause a rapid onset of impaired brain functioning that resolves over time. Symptoms may vary from mild to severe, and they may or may not include loss of consciousness. In some cases, people may not even realize that they have had a concussion. However, it is crucial to recognize that all concussions, regardless of how “mild,” cause injury to the brain and require time and rest to heal properly.
