Study is to determine the predictive values and prognostic accuracies of CSF dynamic measures, the TAP -TEST (high-volume cerebrospinal fluid withdrawal), resistance to CSF outflow and compliance in the prediction of shunt-treatment outcome in patients with idiopathic normal pressure hydrocephalus.
This study evaluates the efficacy of shunt operation for idiopathic normal pressure hydrocephalus, and determines the diagnostic value of noninvasive procedures commonly practiced in the clinic.
The Hospital for Sick Children study is to determine whether infants with triventricular hydrocephalus (TVH) have a better long-term outcome at 5 years when they are treated with a new procedure, endoscopic third ventriculostomy (ETV), than infants treated with the more traditional treatment, insertion of a cerebrospinal fluid (CSF) shunt.
