A subarachnoid hemorrhage is bleeding that occurs in the space between the brain and the tissue that covers the brain (the arachnoid membrane). A subarachnoid hemorrhage may be the result of a blow to the head or other violent impact, such as that sustained in a motor vehicle collision. Subarachnoid hemorrhages can lead to permanent brain damage or death without timely treatment. Unlike some other brain injuries, which are characterized by multiple symptoms, the primary indicator of a subarachnoid hemorrhage is the sudden onset of severe headaches.
