Abstract

We recently reported findings that loss of cortical acetylcholinesterase (AChE) activity is greater in parkinsonian dementia than in Alzheimer's disease (AD). In this study we determined cognitive correlates of in vivo cortical AChE activity in patients with parkinsonian dementia (PDem, n = 11), Parkinson's disease without dementia (PD, n = 13), and in normal controls (NC, n = 14) using N-[(11)C]methyl-piperidin-4-yl propionate ([(11)C]PMP) AChE positron emission tomography (PET). Cortical AChE activity was significantly reduced in the PDem (-20.9%) and PD (-12.7 %) subjects (P < 0.001) when compared with the control subjects. Analysis of the cognitive data within the patient groups demonstrated that scores on the WAIS-III Digit Span, a test of working memory and attention, had most robust correlation with cortical AChE activity (R = 0.61, p < 0.005). There were also significant correlations between cortical AChE activity and other tests of attentional and executive functions, such as the Trail Making and Stroop Color Word tests. There was no significant correlation between cortical AChE activity and duration of motor disease (R = -0.01, ns) or severity of parkinsonian motor symptoms (R = 0.14, ns). We conclude that cortical cholinergic denervation in PD and parkinsonian dementia is associated with decreased performance on tests of attentional and executive functioning.

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.
