A prospective longitudinal study of depression, cognitive decline, and physical impairments in patients with Parkinson's disease.
Open accessAbstract
A consecutive series of 105 patients with Parkinson's disease were examined for the presence of affective disorders, cognitive deficits, and impairments in activities of daily living (ADLs); 92 received the same evaluation 12 months after the initial examination. On the basis of the initial psychiatric findings, patients were divided into major, minor, and non-depressed groups. Patients with major depression showed a significantly greater cognitive decline, deterioration in ADLs, and further advance through the Hoehn and Yahr stages than patients with either minor depression or no depression.

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.
