Relationship of motor symptoms to intellectual deficits in Parkinson disease
Abstract
We studied 60 patients with idiopathic Parkinson disease with motor and neuropsychologic tests to ascertain whether the severity of motor symptoms was associated with the degree of neuropsychologic deficity. Significant correlations were found between the severity of brady kinesia and impaired performance on tests assessing visual-spatial reasoning and psychomotor speed. More severe tremor was associated with better performance on a spatial orientation memory test. There relationships remained when age, age at onset, and self-rated depression were controlled. The findings suggested that cognitive impairment may result from the same subcortical lesions that cause motor symptoms.

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.
