The clinical findings and evolution of these symptoms have been variably defined in the literature.<h4>Objectives</h4>To evaluate how the phenomenology has been defined, assessed, and reported, we performed a critical review of the existing literature discussing the phenomenology of iNPH. The review also identified the instrumental tests most frequently used and the evolution of clinical and radiologic findings.<h4>Methods</h4>The review was divided into 3 sections based on gait, cognitive, and urinary dysfunction. Each section performed a literature search using the terms "idioMovement disorders clinical practice9-16https://www.ebi.ac.uk/biostudies/studies/S-EPMC9847299biostudies-literatureClinical Features of Idiopathic Normal Pressure Hydrocephalus: Critical Review of Objective Findings.PMC9847299Passaretti MMartino DMaranzano ABluett BYoun JVan Gerpen JMalm JAsh EAlonso-Canovas AKrauss JKFarheen AInternational Parkinson and Movement Disorder Society Normal Pressure Hydrocephalus Study GroupFasano ATang-Wai DFfalseClinical Features of Idiopathic Normal Pressure Hydrocephalus: Critical Review of Objective Findings.<h4>Background</h4>Idiopathic normal pressure hydrocephalus (iNPH) is characterized by the classic clinical triad of gait, cognitive, and urinary dysfunction, albeit incomplete in a relevant proportion of patients.
