The typical symptoms of subarachnoid hemorrhage include headache, vomiting, and sudden severe pain, accompanied by vomiting, pale complexion, and whole-body cold sweats. Additionally, there may be disturbances in consciousness and psychiatric symptoms. Most patients do not experience disturbances in consciousness, but may exhibit restlessness and agitation. Severe cases can show varying degrees of clouded consciousness, and even coma, with a few instances displaying seizures and psychiatric symptoms. Furthermore, signs of meningeal irritation are also present, particularly common and pronounced in young and middle-aged patients, characterized by neck stiffness, headaches, and vomiting.
