According to the Brain Injury Association – Concussions are a type of traumatic brain injury (TBI) caused by a blow or jolt to the head. The injury can range from mild to severe and can disrupt the way the brain normally works.
A person does not need to lose consciousness to sustain a concussion. You cannot see a concussion, but you might notice some of the symptoms right away. Other symptoms can show up days or weeks after the injury. It is best to see a health care professional if you think you might have a concussion.
An undiagnosed concussion can affect your abilities at school or work and in everyday activities.
DID YOU KNOW?
• A concussion is the most common type of brain injury sustained in sports.
• Most concussions do NOT involve loss of consciousness.
• You can sustain a concussion even if you do NOT hit your head. An indirect blow elsewhere on the body can transmit an “impulsive” force to the head and cause a concussion to the brain.
• Multiple concussions can have cumulative and long lasting life changes.
• Concussions typically do NOT appear in neuro-imaging studies such as MRI or CAT Scans.
