Syntax Comprehension Deficits in Parkinson??s Disease

LIEBERMAN, PHILIP, FRIEDMAN, JOSEPH, FELDMAN, LIANE S.·1990·The Journal of Nervous and Mental Disease

Abstract

The comprehension of 100 different spoken English sentences was studied in 39 patients with mild to moderate Parkinson's disease (PD) using the Rhode Island Test of Language Structure. Eight of the PD patients were mildly demented, and the remaining 31 showed no cognitive deficits. Seven of the eight mildly demented patients had high comprehension error rates for sentences that had moderately complex syntax. The error rates of 28 of the 31 other, nondemented patients were low, similar to those of normal control subjects. The difference between the error rates of the demented and nondemented patients was significant (p less than .02, two-tailed t-test). The data argue against some current "modular" theories that segregate linguistic from other cognitive behavior. The destruction by PD of the midbrain regions that stimulate the frontal cortex may be responsible for both cognitive and syntactic comprehension deficits.

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.
