Complete recovery can occur after treatment, but death may occur in some cases even with aggressive treatment.

Repeated bleeding is the most serious complication. If a cerebral aneurysm bleeds for a second time, the outlook is significantly worsened.

Changes in consciousness and alertness due to a subarachnoid hemorrhage may become worse and lead to coma or death.

Other complications include:

• Stroke
• Seizures
• Medication side effects
• Complications of surgery

Go to the emergency room or call the local emergency number (such as 911) you have symptoms of a subarachnoid hemorrhage.
