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.
Normal pressure hydrocephalus (NPH) is a form of chronic communicating hydrocephalus, with enlarged cerebral ventricles and intermittently increased cerebrospinal fluid pressure. [ 48 ] [ 33 ] The symptoms include dementia, gait changes, and urinary incontinence. [ 33 ]
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 treatment of cerebral edema depends on the cause and includes monitoring of the person's airway and intracranial pressure, proper positioning, controlled hyperventilation, medications, fluid management, steroids. [3] [7] [8] Extensive cerebral edema can also be treated surgically with a decompressive craniectomy. [7]
An external ventricular drain (EVD), also known as a ventriculostomy or extraventricular drain, is a device used in neurosurgery to treat hydrocephalus and relieve elevated intracranial pressure when the normal flow of cerebrospinal fluid (CSF) inside the brain is obstructed.
A lumbar puncture that drains CSF may also be used as part of treatment for some conditions, including idiopathic intracranial hypertension and normal pressure hydrocephalus. [1] Lumbar puncture can also be performed to measure the intracranial pressure, which might be increased in certain types of hydrocephalus.
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]
When a patient has communicating hydrocephalus, the lateral ventricles and medial parts of the temporal lobes expand and compress the aqueduct. As a result, the pressure within the fourth ventricle drops and causes the aqueduct to close more tightly. This in effect could make aqueductal stenosis a byproduct of hydrocephalus. [8]
