Abstract

According to a cohort study in a Japanese rural area, the prevalence of idiopathic normal pressure hydrocephalus (iNPH) in the 80s was 7.7% among the older inhabitants, despite only a small percentage of the population seeking consultation. The 16-year observation of the cohort revealed that people were in the state of asymptomatic ventriculomegaly with features of iNPH on magnetic resonance imaging or asymptomatic ventricular enlargement several years before presenting symptoms and intracranial changes of iNPH. SFMBT1 was found to be a risk gene for iNPH, and investigating these risk genes will further the study of iNPH pathophysiology.
