Orgasmic Headache Treated with Nimodipine

摘要

Introduction.: Orgasmic headache (OH) is a sudden and severe headache that occurs at the time of or shortly after an orgasm. Aim.: We present the case of typical primary headache associated with sexual activity, especially during an orgasmic period. Methods.: A 34-year-old man complained of sudden and severe headache during sexual activity, or orgasmic period, for 2 months. The headache developed abruptly with an orgasm and then decreased shortly over a period of 4~8 hours. Results.: Magnetic resonance angiography revealed severe spasm of the M1 segment of both the middle cerebral arteries. He was treated with oral nimodipine (30mg every 8 hours), which alleviated the headache and prevented its recurrence. Conclusions.: We postulated a pathophysiological relationship between OH and migraine, especially with respect to vasoconstriction, and believe that in such cases, nimodipine may be an effective therapy.
