WebOne study of 80 patients measured headache intensity before and 10–15 minutes after LP, with “normalization” of cerebrospinal fluid (CSF) pressures to 12–17 cm H 2 O ( 7 ). CSF withdrawal to this pressure range produced headache relief in 72% of patients with IIH. However, there can be a drawback to lowering CSF pressure to a “normalized” range.
