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.
Timed OX1R/OX2R antagonism during the rest phase may consolidate sleep, improve glymphatic/interstitial clearance, and reduce amyloid or tau stress while avoiding daytime cognitive suppression. The therapeutic effect should depend on circadian timing.
