		Normal pressure hydrocephalus (NPH) is a chronic type of communicating hydrocephalus whereby the increase in intracranial pressure (ICP) due to accumulation of cerebrospinal fluid (CSF) becomes stable and that the formation of CSF equilibrates with absorption.
		NPH may be relieved by surgically implanting a ventriculoperitoneal shunt to drain excess cerebrospinal fluid to the abdomen where it is absorbed.
		Normal pressure hydrocephalus is a type of hydrocephalus characterized by increased cerebrospinal fluid and a widening of the ventricles of the brain, usually without causing increased pressure inside the head.

	Medtronic: NPH, normal pressure hydrocephalus, is a condition that affects the elderly
		Normal Pressure Hydrocephalus (NPH) is a neurological condition that affects the elderly.
		NPH is a difficult-to-diagnose disease, since the symptoms often mimic those of other conditions among the elderly — Alzheimer's and Parkinson's.
		NPH is characterized by a triad of symptoms including difficulty walking, poor bladder control, and mild dementia.

	MedFriendly.com: Normal pressure hydrocephalus
		Normal pressure hydrocephalus is a type of hydrocephalus characterized by increased cerebrospinal fluid and a widening of the ventricles of the brain, usually without causing increased pressure inside the head.
		The signs of normal pressure hydrocephalus are caused by distortion of the central portion of the corona radiata, which is due to a widening of the ventricles.
		Normal pressure hydrocephalus was first described in 1965 by Dr. Solomon Hakim while he was training in neurosurgery (surgery of the brain and/or spine) at Massachusetts General Hospital.

	Hydrocephalus and NPH - Overview, Types - neurologychannel
		The word hydrocephalus is derived from two Greek words, hydro, meaning water, and cephalus, meaning head, and once was called "water on the brain." Hydrocephalus is the condition caused by the accumulation of an abnormally large amount of cerebrospinal fluid (CSF) in the skull, or cranium.
		Normally, CSF flows continually from the interior cavities in the brain (ventricles) to the thin subarachnoid space that surrounds the brain and spinal cord.
		Normal flow and absorption through the subarachnoid space is dependent on proper CSF pressure in the head (called intracranial pressure).

	Hydrocephalus Association
		Adult-onset normal pressure hydrocephalus describes those cases that occur in older adults (age 50 and older).

		Background: Normal pressure hydrocephalus (NPH) is a clinical symptom complex characterized by abnormal gait, urinary incontinence, and dementia.
		Normal pressure hydrocephalus may begin with a transient high-pressure hydrocephalus with subsequent ventricular enlargement.
		With further enlargement of the ventricles, CSF pressure returns to normal; thus the term NPH, at least in view of the initial pathophysiologic events, is a misnomer.

	What is Normal Pressure Hydrocephalus (NPH)?
		Normal Pressure Hydrocephalus (NPH) is an excessive accumulation of cerebrospinal fluid (CSF), a water-like substance in the ventricles of the brain.
		With NPH it is believed that the ventricles enlarge to handle the increased volume of the CSF, and the compression of the brain from within by the fluid-filled ventricles destroys or damages brain tissue causing some of the symptoms.
		Unlike Hydrocephalus that typically results in increased pressure in the head when too much CSF accumulates, NPH shows little to no increased pressure, thus leading to the name “Normal Pressure Hydrocephalus”.

	Normal pressure hydrocephalus - Wikipedia, the free encyclopedia
		Normal pressure hydrocephalus (NPH) is a chronic type of communicating hydrocephalus whereby the increase in intracranial pressure (ICP) due to accumulation of cerebrospinal fluid (CSF) becomes stable and that the formation of CSF equilibrates with absorption.
		Diagnosis of NPH is usually first led by a lumbar puncture, followed by the evaluation of clinical response to removal of CSF.
		NPH may be relieved by surgically implanting a ventriculoperitoneal shunt to drain excess cerebrospinal fluid to the abdomen where it is absorbed.

	Normal Pressure Hydrocephalus
		NPH is different from typical hydrocephalus in that it may not cause an obvious increase of pressure in the head, but may have fluctuations in CSF pressure from high to normal to low.
		NPH may be treated using an implantable shunt to drain excess CSF away from the brain and spinal cord.
