A thunderclap headache is a headache that is severe and sudden (like a thunderclap).[1] Because it may be a sign of a medical emergency, some sources recommend immediate medical attention.[1]
In 25% of cases, a thunderclap headache is an indication of aneurysmal subarachnoid hemorrhage (SAH), which often leads to death or severe disability.[2] Headaches which accompany SAH are "frequently described as being the worst headache of one's life, although other clinical presentations are possible."[3]
Diagnosis is made via a process of exclusion with accompanying negative computed tomograph and lumbar puncture results.
