Migrainous vasospasm

Migrainous vasospasm is a subset of reversible cerebral vasoconstriction syndrome (RCVS). It is also known as "crash migraine", although it is sometimes described as a separate condition.

Whether migraine is actually a predisposing factor to RCVS or it is simply that migraine is common (up to 12% of the population) and will, therefore, be reported by patients with RCVS, is uncertain. Migraineurs with RCVS do not report typical migrainous auras and is different from their usual migraines.
