Subarachnoid hemorrhage may recover in 2 months, but it may take longer for the condition to recover. Subarachnoid hemorrhage is a rupture of a blood vessel inside the skull and blood flows into the subarachnoid space. There are many causes of this condition, such as intracranial aneurysms and vascular malformations, etc. In addition, people of advanced age and smoking can increase the risk of developing the condition. If the disease is mild and treated early, the patient usually recovers after 4-6 weeks, while if the disease is severe or not treated timely, the recovery time may take 1-3 months or even longer, depending on the patient’s condition due to large individual differences. After the onset of the disease, in mild cases, there may be no obvious clinical symptoms or signs, while in severe cases, there may be sudden coma or death. The overall prognosis of this disease is poor, the mortality rate is high, and the survivors have a high rate of disability. It is recommended that patients maintain a good attitude and actively cooperate with the doctor’s treatment, in order to facilitate physical recovery.
