The cerebrospinal fluid was collected by tap-test, and 6 months after surgery by puncturing in the VP device pump.\n\nMethods- The primary methods used are:\n\n1. The cerebrospinal fluid proteomic analysis of iNPH patients before and after VP shunt surgery.\n2. The structral and functional MRI analysis of iNPH patients\n3.
