Normal pressure hydrocephalus (NPH) looks at CSF flow values and velocities, which is important for diagnosis because NPH is idiopathic and has varying symptoms amongst patients including urinary incontinence, dementia, and gait disturbances. Increased aqueduct CSF stroke volume and velocity are indicators of NPH. [7]
Normal pressure hydrocephalus (NPH), also called malresorptive hydrocephalus, is a form of communicating hydrocephalus in which excess cerebrospinal fluid (CSF) builds up in the ventricles, leading to normal or slightly elevated cerebrospinal fluid pressure.
The CSF tap test, sometimes lumbar tap test or Miller Fisher Test, is a medical test that is used to decide whether shunting of cerebrospinal fluid (CSF) would be helpful in a patient with suspected normal pressure hydrocephalus (NPH). The test involves removing 30–50 ml of CSF through a lumbar puncture, after which motor and cognitive ...
A test for assessing shunt function in symptomatic hydrocephalus patients. ShuntCheck flow data, used in conjunction with other diagnostic test results and with physician judgment, can aid in ruling in or ruling out shunt obstruction. [1] A tool for establishing “normal” CSF flow patterns in asymptomatic patients.
Hydrocephalus ex vacuo from vascular dementia as seen on MRI. Normal pressure hydrocephalus (NPH) is a particular form of chronic communicating hydrocephalus, characterized by enlarged cerebral ventricles, with only intermittently elevated cerebrospinal fluid pressure. Characteristic triad of symptoms are; dementia, apraxic gait and urinary ...

IIH results in a raised intracranial pressure and can lead to permanent loss of vision. Normal pressure hydrocephalus , also known as Hakim-Adams syndrome Excess cerebrospinal fluid (CSF) occurs in the ventricles, and with normal or slightly elevated cerebrospinal fluid pressure
