TLDR
Cerebral angiography in patients with NPH shows findings characteristic of obstructive hydrocephalus, and early and persistent radioactivity in the ventricles and failure of isotope concentration in parasagittal areas was seen.Abstract:
Radiological findings were reviewed in 41 patients with ventricular shunts because of a diagnosis of occult normal cerebrospinal fluid (CSF) pressure hydrocephalus (NPH). Findings included (a) enlargement of the anterior portion of the lateral ventricle, (b) corpus callosal angle of 120° or less on the anteroposterior film with the patient supine, and (c) wide basilar cisterns with abrupt obstruction of upward gas flow. On cisternography, early and persistent radioactivity in the ventricles and failure of isotope concentration in parasagittal areas was seen. Delay in the rise of the isotope to the parasagittal regions may suggest atrophy. Cerebral angiography in patients with NPH shows findings characteristic of obstructive hydrocephalus.read more

TL;DR: In this paper, a series of patients with idiopathic normal pressure hydrocephalus was divided into two groups on the basis of shunt response and the relative predictive values of preoperative tests.

TL;DR: Ventriculosystemic shunting was beneficial chiefly in patients with communicating hydrocephalus consequent to postmeningeal irritation and the CSF infusion test with fewer false positives was also not diagnostic by itself, thus emphasizing that diagnosis ultimately depends on histology.

The clinical effect of lumbar puncture in normal pressure hydrocephalus.
TL;DR: The CSF-TT seems to be of value when selecting those patients who will probably benefit from a shunt operation, as normal pressure hydrocephalus patients showed temporary improvement after lumbar puncture.

TL;DR: From the combination of tests, cases with obstructive-communicating hydrocephalus can be defined for consideration for ventricular-shunt procedures.

TL;DR: A three year follow-up of 28 patients with idiopathic normal pressure hydrocephalus and an additional 45 patients are presented for further insight into the conclusions drawn from the original experiences of ventricular shunting.

Symptomatic occult hydrocephalus with "normal" cerebrospinal-fluid pressure.a treatable syndrome.
TL;DR: Hydrocephalus is said to be noncommunicating or obstructive if the blockade of circulation is in the ventricular system and communicating or nonobstructive if there is a normal patency of the pathways from the Ventricular system to the lumbar subarachnoid space.

TL;DR: Ventriculoatrial drainage produced significant clinical improvement in all five patients in whom it was undertaken, including two in whom the dementia had been present for some years.

Further experience with the syndrome of "normal" pressure hydrocephalus.
TL;DR: Surgical experience with a total of 28 cases, including five previously reported, reveals marked ventricular enlargement and, in classic cases, a lack of filling of the subarachnoid space over the cerebral convexities following a shunt operation.
