Neuropsychological assessments and cognitive profile mostly associated with shunt surgery in idiopathic normal pressure hydrocephalus patients: diagnostic and predictive parameters and practical implications.

Background: Cognitive decline is a well-documented feature of idiopathic normal pressure hydrocephalus (iNPH) that can be reversible following cerebrospinal fluid tap tests (CSF-TT). The current gold standard for selecting iNPH patients for shunt surgery is measurable improvement in gait tests following CSF-TT. However, the diagnostic significance and predictive role of pre-surgical cognitive evaluations in probable iNPH patients is still controversial.

Acute Presentation of Normal Pressure Hydrocephalus After Transcatheter Aortic Valve Implantation: A Novel Interaction Between the First and Third Circulations.

Background: Idiopathic normal pressure hydrocephalus (iNPH) negatively affects gait and cognition abilities and urine continence in the elderly. It is associated with systemic hypertension, although the exact pathophysiology is still unknown. A correlation to increased intracranial pulsatility and decreased compliance was suggested.
