What causes a coma in head injured people?
Coma in head injured people is usually the result of an injury to all parts of the brain and not just the brain stem. In the majority of cases, a person in a prolonged coma indicates a diffuse injury to all parts of the brain, including the brain stem and in most cases recovery is a slow process. Effects of brain stem injury may include prolonged difficulty with movements, vision, swallowing and other bodily functions controlled by the brain.
