Quantitation of cerebral atrophy in preclinical and end-stage Alzheimer’s disease

de la Monte, Suzanne M.·1989·Annals of Neurology

Abstract

Morphometric analysis of standardized gross cerebral slices from 16 patients with end-stage Alzheimer's disease (AD), 14 controls without neuropathological lesions or neurological disease, and 4 neurologically intact nondemented patients with histopathological lesions of AD was used to measure cross-sectional areas of cerebral cortex, white matter, subcortical nuclei, and the ventricular system. In AD, there was global cerebral atrophy of both cortex and white matter, selective atrophy of the amygdala and hippocampus, and ex vacuo hydrocephalus. In addition, in half the cases of AD, white matter atrophy was associated with overt histopathological evidence of patchy rarefaction of fibers and gliosis. Patients with preclinical AD had prominent and selective shrinkage of white matter comparable to that observed in AD, yet their cortical areas were normal. These observations suggest that white matter degeneration is an intrinsic component of AD. Moreover, its presence in preclinical AD where cortical atrophy is not evident indicates that cytoskeletal abnormalities associated with axonal degeneration may precede and perhaps cause the cortical atrophy observed in clinically manifested AD.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Previous neuroimaging and post-mortem brain studies have observed white matter alterations in the presence of minimal or only weak grey matter atrophy, suggesting that in principle white matter alterations in Alzheimer's disease are not dependent on grey matter atrophy.

    “However, previous neuroimaging as well as post-mortem brain studies have observed white matter alterations in the presence of minimal or only weak grey matter atrophy (de la Monte, 1989; Zhuang et al., 2012), suggesting that in principle white matter alterations in Alzheimer’s disease are not dependent on grey matter atrophy.”

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.
