抄録	Objective To determine the most appropriate assessment scale and timing of the tap test for predicting improvements in dementia severity after shunt surgery in patients with idiopathic normal-pressure hydrocephalus (iNPH). Methods Data were extracted from an observational study that followed patients with iNPH as follows: Patients diagnosed with possible iNPH and scheduled for a tap test were enrolled. Patients diagnosed with probable iNPH by the tap test underwent shunting and followed up for 3 months after shunting. Patients with missing data in the tap test assessment items (gait speed: 3 consecutive days before tapping and 3 consecutive days after tapping; cognition: before tapping, 1 day after tapping and 1 week after tapping; and urinary dysfunction: before tapping and 1 week after tapping) or in the Clinical Dementia Rating (CDR) assessed before tapping and 3 months after shunting were excluded from this study. Results 54 patients were included in the analysis. The change in CDR-Sum of Boxes (CDR-SoB) score after shunt surgery was significantly correlated with the change in Mini-Mental State Examination (MMSE) score (β = −0.417, p < 0.001) and Frontal Assessment Battery (FAB) score (β = −0.379, p = 0.002) 3 months after shunt surgery after adjusting for age and sex. The change in MMSE score after shunt surgery was correlated with the change in MMSE score 1 day after tapping (β = 0.411, p = 0.001), the change in the minimum Timed Up and Go test score across repeated tests after tapping (β = −0.376, p = 0.004) and attention/concentration in Wechsler Memory Scale-Revised 1 day after tapping (β = −0.289, p = 0.024). The change in FAB score after shunt surgery was correlated with the change in the maximum FAB score across repeated tests after tapping (β = 0.523, p < 0.001). Conclusion Combining MMSE and FAB assessments during the tap test may yield more useful information in assessing cognitive impairment than using either MMSE or FAB alone.
