Evidence for Degenerative and Regenerative Changes in Neostriatal Spiny Neurons in Huntington's Disease

Graveland, G. A., Williams, R. S., DiFiglia, M.·1985·Science

Abstract

Golgi impregnations of neostriatum from deceased Huntington's disease patients and controls were examined. In all cases of Huntington's disease the morphology of dendrites of medium-sized spiny neurons was markedly altered by the appearance of recurved endings and appendages, a decrease or increase in the density of spines, and abnormalities in the size and shape of spines. Pathological changes were rarely observed in medium-sized and large aspiny neostriatal neurons. The findings provide evidence for simultaneous degeneration and growth of spiny neurons in Huntington's disease and support the view that a specific population of neostriatal neurons is selectively involved in its pathogenesis.

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.
