Symptomatic Occult Hydrocephalus with Normal Cerebrospinal-Fluid Pressure: A Treatable Syndrome

Adams, R. D., Fisher, C. M., Hakim, S., Ojemann, R. G., Sweet, W. H.·1965·New England Journal of Medicine

Abstract

THE term hydrocephalus refers to distention of the cerebral ventricles, usually as the result of obstruction somewhere along the pathway of the cerebrospinal-fluid circulation. Occult indicates that enlargement of the ventricles has occurred after union of the cranial sutures, and hence the head remains of normal size. 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. Its causes are numerous and include tumors encroaching on the ventricles, carcinomatosis of . . .

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
