Is a concussion a mild brain injury?
In some cases a concussive injury can produce a mild brain injury. A concussion is a temporary injury. However, a concussive injury can lead to stretching and tearing of nerve fibers in the brain, producing longer-term effects. These injuries usually don’t show up in CAT scans and neurological examinations. In some cases, since the person never “lost consciousness” a full neurological exam never takes place. The cognitive, emotional and physical results of a concussive injury are called Post Concussion Syndrome (PCS).
