Abstract

OBJECTIVE: To determine whether serum trace metals and oxidative species are related to abnormal cognition in AD. METHODS: The authors studied serum peroxides, copper, iron, transferrin, and antioxidant capacity in 79 patients with AD (mean age 74.3 years; 25 men, 54 women) and in 76 cognitively normal individuals (mean age 70.1 years; 33 men, 43 women). The relation of these oxidative and trace metals to APOE epsilon4 allele frequency, neuropsychological performance, and cerebrovascular or atrophic burden, as estimated by brain MRI and ultrasonography of cerebral vessels, was evaluated. RESULTS: Copper level was higher (p < 0.001) in subjects with AD than control subjects (specificity = 95%, sensitivity = 60%) with a cutoff serum level of 16 micro mol/L (1.02 mg/L). An increase of 1 micro mol/L in serum copper accounted for 80% of the risk of having AD and correlated with poor neuropsychological performance and medial temporal lobe atrophy (p < 0.03). Antioxidant capacity decreased and correlated with medial temporal lobe atrophy (p < 0.009) and with APOE epsilon4 allele (p = 0.004). CONCLUSIONS: Copper may play a role in neurodegenerative processes in AD, and serum copper measurement may prove to be a peripheral diagnostic marker for AD.

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.
