When you hit your head twice and have no symptoms, a relatively heavy collision may cause some damage to the brain, while a relatively light collision may cause no obvious damage.
1. There is a possibility of brain damage even if you hit your head twice and have no symptoms. If the collision is heavy and the damaged brain tissue is not a functional area, there may be a performance of hitting your head with no symptoms; in addition, some people may have brain damage but have no symptoms at that time, and may have epilepsy and other manifestations afterward.
2. In the case of a mild collision, when there are no symptoms, there may be no obvious damage to the brain, but there may be delayed intracranial hematoma, and it is recommended that a CT scan of the head be performed to make a clear diagnosis.
If the collision is heavier, the head needs to be examined, such as cranial CT, cranial MRI, etc., to clarify whether there is any damage foci. In addition, you should also closely observe whether there is any abnormal mental state and other manifestations after the head banging, if there is any discomfort, you should promptly go to the hospital and follow the doctor’s instructions for treatment.
