Abstract

Objective To assess glial and neuronal density and neuronal volume in two areas of the caudate nucleus in late-life major depression.Design A postmortem study using the disector and nucleator methods to estimate neuronal density and volume and glial density of cells from human brain tissue from the anterior portion (dorsolateral and ventromedial aspects) of the caudate nucleus.Setting Brain tissues were obtained from the Newcastle Brain Tissue Resource at Newcastle University, UK.Participants The study group consisted of 13 subjects with late-life major depression and nine comparison subjects of similar age.Results Evidence of moderate reductions in neuronal density was found in the depressed group in both the dorsolateral and ventromedial areas of the caudate nucleus. There were no significant changes in glial density or neuronal volume in either area nor was there any evidence of differences in depression in early and late-onset subgroups.Conclusions Neuroimaging abnormalities in frontal and subcortical areas including ischemic hyperintensities and a reduction in volume and metabolism in the caudate nucleus have been reported in late-life depression, and previous morphometric studies have reported neuronal changes in prefrontal cortical areas. The findings in this study extend these morphometric investigations in late-life depression to the caudate nucleus, suggesting that neuronal abnormalities are present in this subcortical nucleus as well as in these related prefrontal areas.

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.
