Thunderclap headache
From Wikipedia, the free encyclopedia
A thunderclap headache is a sudden and severe headache.[1] Since it is sometimes a sign of a medical emergency, one should "[s]eek immediate medical attention for any headache that comes on suddenly and severely."[1]
The name "thunderclap" signifies the intensity and acuity of such headaches. A thunderclap headache is sometimes an indication of subarachnoid hemorrhage (SAH),[2] which can lead to death or severe disability even if recognized and treated in an early stage. Headaches which accompany SAH are "frequently described as being the worst headache of one's life, although other clinical presentations are possible."[2]
Diagnosis is made via a process of exclusion with accompanying negative computed tomograph and lumbar puncture results.
