Post-Lumbar Puncture Headache: Clinical Features and Suggestions for Diagnostic Criteria

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%; p<0.001) First onset of PPH occurred within the first day in 40 patients (53%), within 2 days in 89%, and never after the fourth day. When PPH occurred for the first time on the day the lumbar puncture was performed, it was usually experienced much later in the day (median 14.00 h) than it first occurred on the second day (median 09.30 h) or later. The median duration of PPH was 6 days (range 1–29 days). Patients with headache performed a “Rising Manoeuvre” twice daily as long as the headache period lasted, and recorded pair and time variables. The severity of PPH was negatively correlated to the time till the headache started or worsened upon rising (T1 and the time...
