  1. For INPH patients, data were collected before the CSFTT. Values denote number (%) or mean ± standard deviation. INPH = idiopathic normal-pressure hydrocephalus; CSFTT = cerebrospinal fluid tap test; K-MMSE = Korean version of Mini-Mental State Examination; CDR = Clinical Dementia Rating Scale; INPHGS = Idiopathic Normal-Pressure Hydrocephalus Grading Scale; GS-Gait = INPHGS for gait; GS-Cogn = INPHGS for cognition; GS-Urin = INPHGS for urinary function; TUG = Timed Up-and-Go test; GSS = Gait Status Scale; FAB = Frontal Assessment Battery.
