Abstract

Significant loss of neurons in the pedunculopontine nucleus pars compacta (PPNc), a putative cholinergic nucleus involved in modulating somatic motor activities, has been demonstrated in progressive supranuclear palsy (PSP) and Parkinson's disease but not in Alzheimer's disease. A morphometric study of this nucleus was performed in two cases of PSP and in a cohort of cases of Parkinson's disease, Alzheimer's disease, senile dementia of Alzheimer type (SDAT), and age-matched controls. In PSP a significant 60% neuronal loss in PPNc was associated with neurofibrillary tangles in 40 to 64% of the remaining neurons. In Parkinson's disease there was a significant decrease in cell numbers and density by 53 and 51%, respectively, with Lewy bodies involving 6 to 39% of all neurons. In Alzheimer's disease and SDAT, large neurons were reduced by 29 and 33.8%, respectively, with tangles in 9 to 38% of the remaining cells. The selective affection of this putative cholinergic nucleus in PSP and Parkinson's disease appears to be related to motor dysfunctions in these disorders.

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.
