When a patient with cerebral infarction falls on his head, his condition may be mild or serious, and it is related to the degree of brain damage caused by the fall. If a patient with cerebral infarction falls on his head but has no obvious symptoms of brain injury, and only has a mild headache, the condition is generally not serious; if the brain injury caused by the fall is more serious, such as skull fracture, cerebral contusion, epidural hematoma, subdural hematoma, cerebral hemorrhage, etc., the condition is more serious, and the serious cases can be life-threatening at any time. After a patient with cerebral infarction falls on his head, it is recommended that he should seek medical treatment in time to improve the examination of cranial CT and other examinations, combined with the clinical manifestations, to assess the degree of injury and give symptomatic treatment, so as to avoid delaying the condition.
