Filter by:This study will determine the level of association between the quantitative estimates of brain uptake of [18F]flutemetamol and the quantitative immunohistochemical estimates of amyloid levels in biopsy samples previously obtained during shunt placement in patients who have normal pressure hydrocephalus (NPH).
The purpose of the 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.
The purpose of this study is to examine the role of ShuntCheck and MR Imaging in evaluating the presence or absence of Shunt Obstruction in the patients of Hydrocephalus or Idiopathic Intracranial Hypertension (IIH) undergoing radionuclide test for suspected shunt obstruction. This is an exploratory study to determine how a non-invasive device can assist in detection of presence of flow in these patients.
This study aims to provide class 1 evidence supporting or refuting the existence of normal pressure hydrocephalus.
The research project is designed to determine which combination of tests will enable physicians to predict whether a patient with symptoms of normal pressure hydrocephalus (NPH) will improve with a shunt.
Correlation of cerebrospinal fluid levels of transforming growth factor beta-1 with functional improvements after insertion of ventriculoperitoneal shunt for normal pressure hydrocephalus
The overall aim of the registry is to develop a longitudinal, observational database that is focused on adult patients with Normal Pressure Hydrocephalus (NPH) that can be used as a source of clinical information for individual surgeons, as well as a national data repository for scientific inquiry and publications.
The purpose of this study is to determine the agreement rate between the CODMAN Valve Position Verification (VPV) adjustment outcome (reprogramming) and X-ray verification in order to support an alternative to X-ray confirmation with respect to the valve adjustment process.
Hydrocephalus (secondary or idiopathic) is a condition characterized by dilatation of the lateral and third ventricles, and often associated with increased intracranial pressure (ICP). We hypothesize that either the ventricle dilatation or the increased ICP may cause disturbances in the hypothalamic-pituitary axis, resulting in different degrees of hypopituitarism. The goal of this study is to determine the prevalence of hypopituitarism in adult patients with hydrocephalus.
