Patients with subarachnoid hemorrhage generally have aneurysms or arteriovenous malformations as the cause. After onset, the main symptom is usually headache, with positive meningeal irritation signs found during examination, but no signs of neurological function deficit. Therefore, during the recovery phase, patients generally do not show positive neurological signs and have good limb mobility. It is only necessary to take precautions against the cause of the disease. For instance, if the patient's cerebral aneurysm has not been surgically treated, there could be a risk of rebleeding. Patients should minimize physical activity, rest in bed as much as possible, and avoid aneurysm rupture. Regular blood pressure control is also essential. If the cause has already been addressed, there are not many precautions needed. Additionally, long-term administration of nimodipine is necessary to prevent delayed cerebral vasospasm, generally recommended for a period of four to six months. (Medication should be used under the guidance of a doctor based on specific conditions.)
