Hippocampal volume as an index of Alzheimer neuropathology: Findings from the Nun Study

Abstract

OBJECTIVE: To determine whether hippocampal volume is a sensitive and specific indicator of Alzheimer neuropathology, regardless of the presence or absence of cognitive and memory impairment. METHODS: Postmortem MRI scans were obtained for the first 56 participants of the Nun Study who were scanned. The area under receiver operating characteristic curves, sensitivity, specificity, and positive and negative predictive values were used to assess the diagnostic accuracy of hippocampal volume in predicting fulfillment of Alzheimer neuropathologic criteria and differences in Braak staging. RESULTS: Hippocampal volume predicted fulfillment of neuropathologic criteria for AD for all 56 participants (p < 0.001): 24 sisters who were demented (p = 0.036); 32 sisters who remained nondemented (p < 0.001), 8 sisters who remained nondemented but had memory impairment (p < 0.001), and 24 sisters who were intact with regard to memory and cognition at the final examination prior to death (p = 0.003). In individuals who remained nondemented, hippocampal volume was a better indicator of AD neuropathology than a delayed memory measure. Among nondemented sisters, Braak stages III and VI were distinguishable from Braak stages II or lower (p = 0.001). Among cognitively intact individuals, those in Braak stage II could be distinguished from those in stage I or less (p = 0.025). CONCLUSION: Volumetric measures of the hippocampus may be useful in identifying nondemented individuals who satisfy neuropathologic criteria for AD as well as pathologic stages of AD that may be present decades before initial clinical expression.

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.
