Other related information
Evaluations of gait, cognition, urination, and other symptoms, neuroimaging studies, and assessments of biomarkers in cerebrospinal fluid were performed before and after shunt surgery in iNPH patients. The evaluations after shunt surgery are repeated for five years. We analyze the association between results of the evaluation before shunt surgery and the outcome 5 years after shunt surgery.
