Daytime orexin tone preserves synaptic plasticity in prodromal AD
🧪 Overview
In prodromal AD with circadian flattening, insufficient daytime orexin signaling may reduce attention and hippocampal plasticity. A chronotherapy strategy that preserves daytime orexin tone while blocking night hyperarousal may outperform uniform receptor blockade.
