title: [Thunderclap headache].
abstract: Thunderclap headache is a warning symptom that may reveal a number of severe underlying causes, the most frequent being vascular disorders. The search for a cause should be expedient and exhaustive. In the absence of an identified cause, the international headache classification suggests to consider the diagnosis of primary thunderclap headache, which remains controversial.
