Neuropsychologic Findings in Hypoxemic Chronic Obstructive Pulmonary Disease
Abstract
As part of a six-center clinical trial of the effectiveness of continuous v nocturnal oxygen in the management of hypoxemic chronic obstructive pulmonary disease (COPD), we performed detailed neuropsychologic assessments of these patients prior to their beginning treatment. The 203 patients (age, 65 years; Pao2, 51 mm Hg; forced expiratory volume in 1 s, 0.74 L) performed significantly worse than controls on virtually all neuropsychologic tests. Moderate to severe test impairment suggestive of cerebral dysfunction was found in 42% of the patients, as compared with 14% of controls. Higher cognitive functions (abstracting ability, complex perceptual-motor integration) were most severely affected, although half the patients also showed decrements in motor speed, strength, and coordination. Low-order significant inverse correlations were found between neuropsychologic impairment and Pao2, resting arterial oxygen saturation and hemoglobin levels and maximum work. It is concluded that cerebral disturbance is common in hypoxemic COPD and may be related in part to decreased availability of oxygen to the brain.

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.
