Idiopathic stabbing headache (jabs and jolts syndrome).

The clinical features of idiopathic stabbing headache ("jabs and jolts syndrome") were studied in 38 patients who were diagnosed throughout a 1-year period. Mean age at the onset of symptoms was 47.1 years +/- 14.5 (SD), and a clear female preponderance was demonstrated (female/male ratio = 6.6). Painful attacks were ultrashort, i.e. virtually all attacks in more than two thirds of cases lasted only one second. The frequency of attacks varied immensely, ranging from 1 attack per year to 50 attacks daily. The pain paroxysms usually occurred with an irregular or sporadic temporal pattern. The localization of painful attacks was reported frequently as unifocal, usually in the orbital area, but also multifocal patterns were observed, the attacks frequently changing location from one area to the next. The majority of attacks occurred spontaneously, and accompanying phenomena were reported only rarely. Indomethacin treatment (75 mg daily) seemed to have a complete or partial effect in most patients treated as such (n = 17).
