The first thing to do is to go to the hospital and have a CT scan to see if there is any intracranial hemorrhage or skull fracture. If the first CT examination shows no intracranial abnormality, the patient should be instructed to go home for close observation to prevent the possibility of delayed intracranial hemorrhage, and to go home to observe closely for symptoms such as aggravation of headache, nausea, vomiting, confusion, and paralysis of limbs. Once the above symptoms occur, the patient should go to the hospital again for a repeat CT examination to determine whether there is any possibility of delayed intracranial hemorrhage. If the first CT scan indicates intracranial hemorrhage or skull fracture, the patient should be hospitalized and treated conservatively or surgically depending on the amount of bleeding. If the amount of bleeding is >30 ml in the cerebral hemisphere and >10 ml in the cerebellar hemisphere, craniotomy should be performed to remove the hematoma. If the bleeding volume is less than 30 ml in the cerebral hemisphere and less than 10 ml in the cerebellar hemisphere, the patient can be treated conservatively with drugs.
