Ischaemic stroke provoked by sexual intercourse

Abstract

The association between long term risk factors and stroke has been well established, but very little is known about factors that may precipitate acute stroke. We describe two young women presenting with ischaemic stroke triggered by sexual intercourse. Patient 1 presented with a cardioembolic stroke probably secondary to the interaction between a patent foramen ovale and thrombophilic abnormalities; Patient 2, presenting with orgasmic headache, had a cryptogenic striatocapsular infarct. Sexual intercourse should be considered as an unusual, but possible, trigger of cerebral ischaemia, especially in young patients presenting with cryptogenic stroke.
