Although the pathophysiology of idiopathic normal pressure hydrocephalus (iNPH) remain largely unknown, it is well acknowledged that iNPH causes ventricular enlargement due to decreased cerebrospinal fluid (CSF) absorption. Pathophysiologically, it is supposed that the excretion of waste proteins is impaired along with CSF. Hence, they tend to aggregate, and in many neurodegenerative diseases, abnormal aggregation and accumulation of such proteins are deeply involved in the pathogenesis of disease. Biomarkers (BMs) contribute to diagnosis by identifying comorbid neurodegenerative diseases that may affect the prognosis of treatment, as well as exploring the pathogenetic mechanisms of iNPH. In addition, BMs can be an important prognostic test for shunt therapy.
