Structural Correlates of Cognition in Dementia: Quantification and Assessment of Synapse Change
Abstract
Dementia results from a combination of structural and neurochemical pathologies. The most reliable index of cognition in both postmortem and biopsied AD brain is synapse loss.

Synapse loss closely correlates with degree of cognitive impairment in AD.
“Synapse loss appears particularly relevant because it closely correlates with degree of cognitive impairment (Terry et al., 1991;DeKosky et al., 1996;Coleman and Yao, 2003).”

Decreased cortical synapse density correlates with cognitive decline in patients.
“decreased cortical synapse density correlates with cognitive decline in patients (Terry et al., 1991;DeKosky et al., 1996).”

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.
