Brain injuries are generally disorders caused by violence to the head, among other things, and are not usually associated with genetic aspects.
Brain injuries mainly include primary injuries such as concussions, contusions, diffuse axonal injuries, and secondary injuries such as cerebral edema, brain swelling, and intracranial hematomas. Brain injuries are mainly due to the effects of violence and are not genetically related.
The basic factors causing brain injury are: brain injury due to skull depression and rebound or fracture when violence is applied to the head; and injury caused by the relative motion between the brain and the skull in the instant after violence is applied to the head.
If a brain injury occurs, you should seek prompt medical attention and active treatment under the guidance of a doctor to avoid delays.
