Normal pressure hydrocephalus: Diagnostic and predictive evaluationon
In typical cases, normal pressure hydrocephalus (NPH) manifests itself with the triad of gait disturbance, which begins first, followed by mental deterioration and urinary incontinence associated with ventriculomegaly (on CT or MRI) and normal cerebrospinal fluid (CSF) pressure. These cases present minor diagnostic difficulties and are the most likely to improve after shunting. Problems arise w...
متن کاملShunting normal pressure hydrocephalus: the predictive value of combined clinical and CT data.
The value of an ordinal global scale derived from combined clinical and CT data (clin/CT scale) to predict the clinical outcome in 112 patients shunted for presumed normal pressure hydrocephalus (NPH) was analysed. The clinical data were retrospectively collected, all CT scans were re-evaluated, and the clin/CT scale was determined blind to the results of further ancillary tests and to the post...
متن کاملThe value of supplemental prognostic tests for the preoperative assessment of idiopathic normal-pressure hydrocephalus.
OBJECTIVE The diagnosis and management of idiopathic normal-pressure hydrocephalus (INPH) remains unclear. Moreover, the value of supplementary tests to predict which patients would benefit from placement of a shunt has not been established. This report develops evidence-based guidelines for the use of supplementary tests as an aid in prognosis. METHODS MEDLINE searches from 1966 to the prese...
متن کاملThe Predictive Value of the Tap-test in Normal Pressure Hydrocephalus
Normal pressure hydrocephalus (NPH) represents 1 to 12% of dementias. It is characterized by gait disturbance, progressive mental deterioration and urinary incontinence, associated with enlargement of the ventricular system and normal cerebrospinal fluid (CSF) pressure. In typical cases, gait disturbance is the first and most salient sign, followed by forgetfulness or mild dementia, psychomotor...
متن کاملThe predictive value of cerebrospinal fluid tap-test in normal pressure hydrocephalus.
Eighteen patients (mean age of 66.5 years) with normal pressure hydrocephalus (NPH) underwent a ventriculo-peritoneal shunt surgery. Prior to operation a cerebrospinal fluid tap-test (CSF-TT) was performed with measurements of gait pattern and psychometric functions (memory, visuo-motor speed and visuo-constructive skills) before and after the removal of 50 ml CSF by lumbar puncture (LP). Fifte...
