〔Abstract〕 Idiopathic normal pressure hydrocephalus (iNPH) is a clinical syndrome characterized by triad of gait disturbance, cognitive impairment, and urinary incontinence. After cerebrospinal fluid shunt surgery, the clinical symptoms of iNPH can be improved to varying degrees, so the disease is considered to be a treatable dementia. With the further exploration of the disease by researchers, new progress has been made in the studies on radiographic imaging of iNPH. This study reviewed the current status of radiographic researches on iNPH from three aspects: assessment of ventriculomegaly, changes in brain networks, and abnormalities in white matter fibers.
