Abstract

The effect of hyperglycemia on hormone levels, metabolite levels, and memory performance was examined in 22 subjects with very mild and mild probable dementia of the Alzheimer type (DAT) and in 12 normal elderly adults. Subjects were tested in 3 plasma glucose conditions (fasting baseline, 175 mg/dl, and 225 mg/dl) at initial and 18-month follow-up sessions. Initially, adults with very mild DAT showed memory facilitation and elevations in plasma insulin in the 225-mg/dl glucose condition relative to baseline. At follow-up, very mild DAT patients whose dementia had progressed showed significant decreases in insulin and hyperglycemic memory facilitation. Changes in basal insulin and cortisol levels over time were correlated with memory changes for DAT subjects. These results suggest that glucoregulatory abnormalities may contribute to the pathophysiology of DAT.

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?

  • Elevated glucose levels, indexed by fasting glucose or glycosylated hemoglobin, are related to heart disease risk, higher mortality, and poorer cognitive and physical function.

    “Elevated glucose levelsas indexed by fasting glucose or more integrated assessments of glucose metabolism such as glycosylated hemoglobin (HgA1c)-have also been related to heart disease risk; 15 to higher mortality; 16 and to poorer cognitive [17][18][19][20] and physical function.8”

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.
