Causes of Subarachnoid Hemorrhage         

  • Most often it happens because a bulge in the wall of an artery (saccular aneurysm) ruptures.
  • It can also occur because blood leaks from an abnormal tangle of blood vessels called an arteriovenous malformation (AVM). AVMs form accidentally prior to birth

Medical advice for Subarachnoid Hemorrhage         

  • Less-intense headaches should be evaluated by your doctor if you have them often or if they are accompanied by symptoms such as nausea, vomiting, weakness or numbness in any part of the body.
  • If you have a sudden, very severe headache but it goes away, it is critically important to discuss this with your doctor. Sometimes blood leaks briefly from a blood vessel 6 to 20 days before a subarachnoid hemorrhage occurs. The headache this leak causes is called a sentinel headache. Your doctor may be able to provide treatment that can prevent more serious bleeding.
