How is the headache of subarachnoid hemorrhage often described?
Headache following subarachnoid hemorrhage is often described by patients as “the worst headache of my life” or as a “thunderclap headache.” A thunderclap headache has been described as an acute, severe, and explosive headache that immediately reaches maximal intensity. The term “thunderclap headache” originates from 1986 from Day and Raskin, because of the similarities to being struck by a thunderbolt.
