Nucleus raphe dorsalis in Alzheimer's disease: Neurofibrillary tangles and loss of large neurons

Yamamoto, Toru, Hirano, Asao·1985·Annals of Neurology

Abstract

Diffuse serotonergic fibers are presumed to project to the talencephalon from the nucleus raphe dorsalis (NRD) of the mid brain, in a manner similiar to the cholinergic projections from the nucleus basalis of Meynert (nbM) to the cerebral cortex. Neuropathological changes in both of these nuclei have been reported in Alzheimer's disease (AD). Although many morphometric studies of the nbM in AD have been documented, only one such study of the NRD has been documented, only one such study of the NRD has been conducted so far; it demonstrated a six fold increase in neurofibrillary tangles in AD but no statistically significant difference in the number of neurons in patients with AD and age‐matched controls. A study of the NRD utilizing different stains and wider anatomical boundaries is detailed in this report of 5 patients with AD and 7 age‐matched controls. In AD the NRD showed 39 times more neurofibrillary tangles and the number and cell density of large neurons were reduced to 23% and 28%, respectively, of those in the controls. A small number of senile plaques were found in the NRD in all patients with AD but none were found in the controls.

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.
