Abstract

Soluble amyloid-β protein (Aβ) may cause cognitive impairment in Alzheimer's disease in the absence of significant neurodegeneration. Here, the ability of the NMDA receptor (NMDAR) antagonist memantine to prevent synthetic Aβ-mediated rapid functional deficits in learned behavior and synaptic plasticity was assessed in the rat. In vitro, pretreatment with a clinically relevant, NMDAR blocking concentration of memantine partially inhibited the induction of long-term potentiation (LTP) in the dentate gyrus and prevented further inhibition caused by exposure to Aβ(1-42). Whereas systemic injection with memantine alone inhibited LTP in the CA1 area in vivo, a subthreshold dose partially abrogated the inhibition of LTP by intracerebroventricular soluble Aβ(1-42). Similarly, systemic treatment with memantine alone impaired performance of an operant learning task and a subthreshold dose prevented the Aβ(1-42)-mediated increase in perseveration errors. The acute protection afforded by memantine, albeit in a narrow dose range, against the rapid disruptive effects of soluble Aβ(1-42) on synaptic plasticity and learned behavior strongly implicate NMDAR-dependent reversible dysfunction of synaptic mechanisms in Aβ-mediated cognitive impairment.

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.
