Analysis of Lumbar Puncture Test in 5 Patients with Good Prognosis of Shunt Operation for Normal Pressure Hydrocephalus

ABSTRACT

Five patients with favorable outcomes after a shunt operation in normal pressure hydrocephalus were analyzed with the aim of identifying consistent findings in a lumbar puncture (LP) test. The cases commonly showed improvement in at least one cognition and two gait LP parameters. We suggest that when judging the effects of LP on a shunt operation, the gait parameters need to be tailored to the gait status and the analyzed LP parameters should be evaluated at least twice at different times.
