Subarachnoid hemorrhage is a form of stroke characterized by bleeding in the subarachnoid region of the brain - the area between the brain the tissues that cover it.

While subarachnoid hemorrhage is rare, accounting for around 3 percent of all strokes, it can have serious consequences, causing paralysis, coma, and death.

A sudden, severe headache is the primary symptom of subarachnoid hemorrhage, and this most commonly occurs at the back of the head. Other symptoms include reduced consciousness and alertness, changes in mood and personality, and eye discomfort in response to bright light.
