Abstract
The aim of the present prospective study was to describe clinical features of post-lumbar puncture headache (PPH), and to test the validity of the diagnostic criteria of the International Headache Society (IHS). Eighty-eight of the 239 included patients (36.8%) experienced PPH. Females were affected more frequently than males (45.2% vs 21.4%; p1 and the time from the headache started to increase till it reached its maximum (T2) but was not significantly correlated to the time to restitution upon lying down (T3). The results are in good accordance with the leakage theory. T1 varied from immediate onset to 265 min (median 20 sec). T2 (median 30 sec, range 0–60 min) and T3 (median 20 sec, range 0–15 min) varied considerably as well. During the course of PPH, 45% of the patients occasionally reported non-postural headache or no headache when the Rising Manoeuvre was performed. It is suggested that PPH should be diagnosed in any patient who experiences postural headache at least once within 4 days of lumbar puncture.
