How To Treat A Subarachnoid Hemorrhage

A subarachnoid hemorrhage occurs when there is bleeding between the brain and the subarachnoid space surrounding it. Most cases present with a sudden and severe headache. It's also possible for the headache to cause vomiting, nausea, and loss of consciousness. In most cases, the bleeding occurs when an aneurysm in the brain ruptures. An aneurysm is an abnormal bulge that forms in a blood vessel. Some aneurysms can be treated before they rupture, while others can only be monitored. The bleeding can sometimes also be a result of trauma and injury. In rarer cases, other health issues and blood vessel problems can cause this type of bleeding. Abnormal tangles of blood vessels called arteriovenous malformations can cause this bleeding in the brain.
