Subarachnoid Hemorrhage

Subarachnoid hemorrhage is a neurological emergency that requires immediate attention. It consists of bleeding in the space surrounding the brain, between the membranes that cover it, and can rapidly threaten a person's health.

Characteristic sign: It usually begins with a sudden, intense headache, described as the worst the person has ever felt, sometimes with a stiff neck, vomiting, sensitivity to light, or loss of consciousness.

Common causes: It is often related to the rupture of an aneurysm or to trauma.

Who treats it? When these symptoms appear, you must go to the emergency room immediately; the neurosurgeon and the neurologist are the specialists who evaluate and provide follow-up. It's best not to wait: a headache this sudden should be assessed without delay.
