A Guide to Recognizing and Treating Concussion Symptoms A concussion is the most common and least dangerous type of traumatic brain damage. Concutere is a Latin word that means "to shake violently." A concussion is most commonly induced by a direct impact on the head.
Concussion: What Is It? Concussions are a type of mild traumatic brain injury (TBI), and while a violent blow to the head typically brings them on, other types of brain damage can also result in them. The hard, skeletal skull surrounds the soft substance that is the brain. The brain's nerve fibres sustain damage if the brain is jolted during a traumatic event. This results in a number of dysfunctions when the nerves cannot communicate with one another.
What causes concussions? The soft tissue that makes up the brain. It is protected by the skull's protective layer and cushioned by spinal fluid. The force of a strike or bump on the head might cause a brain shock.
