Generally speaking, if the cerebral bruising is relatively mild, not accompanied by impairment of the patient’s mental faculties, and no disability occurs, but only a small part of the brain contusion, such as this can basically recover in two weeks as before, and in another two weeks can work and study normally. However, in clinical cases, brain bruises after a car accident need to be removed by surgical craniotomy, which means that the condition is more serious and even causes coma and even respiratory and heartbeat disorders. Such a condition is more severe and often requires more time to recover. If it is accompanied by disability, it may take up to three months to recover a certain degree of physical and self-care ability, so it must be judged according to the condition at the time. It is important to actively treat the disease at an early stage to reduce the adverse reactions at a later stage.
