A thunderclap headache is a sudden and severe headache.[1] Since it is sometimes a sign of a medical emergency, one should "seek immediate medical attention for any headache that comes on suddenly and severely."[1] The name "thunderclap" signifies the intensity and acuity of such headaches.
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 tomography and lumbar puncture results.
