Association of cerebrospinal fluid tap‐related oscillatory activity and shunt outcome in idiopathic normal‐pressure hydrocephalus

Idiopathic normal‐pressure hydrocephalus (iNPH) is a neuropsychiatric syndrome characterized by the clinical triad of gait disturbance, urinary dysfunction, and cognitive impairment. The aim of the present study was to find specific EEG patterns associated with shunt response in iNPH.
