Background and purpose Evans index is an estimate of ventricular size used in the diagnosis of idiopathic normal‐pressure hydrocephalus (iNPH). Values >0.3 are considered pathological and are required by guidelines for the diagnosis of iNPH. However, there are no previous epidemiological studies...
