Demography and clinical data from NPH patients and controls. Data were presented as mean (±standard deviation) unless indicated otherwise. NPH = Normal Pressure Hydrocephalus; MMSE = Mini mental state examination. For age, independent t-test was performed which came out as significant (p < 0.05).

Characteristics of the sample	Control (NNC)^a	NPH
Total samples	13	23
Age (Mean ± SD)	58.07 ± 9.47	72.78 ± 9.15
Gender	Male 4; Female 9	Male 13; Female 10
Disease duration (Mean ± SD)	–	32 months ± 63 months^b
MMSE Score (Mean ± SD)	–	23.17 ± 7.34^c

Control subjects might have other non-neurological ailments but not NPH, hence given the name Non-NPH Control (NNC). MMSE evaluation was not carried out in NNC subjects.

Data from 5 patients were not obtained; Disease duration of one patient was 276 months which caused high SD.
