Chronic orexin-A elevation may aggravate AD by extending wakefulness, fragmenting circadian rhythms, and increasing activity-dependent amyloid/tau release. Lowering orexin tone should improve pathology only when it normalizes sleep rather than causing broad hypoarousal.
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.

Orexin-A may be therapeutic only when the intervention restores circadian phase and sleep architecture. Nighttime OX1R/OX2R antagonism could improve glymphatic clearance, whereas daytime orexin tone m...

The same arousal pathway can increase amyloid production by extending wakefulness. A rescue claim must show that benefits are not merely sedation, reduced activity, or nonspecific sleep extension....

The translational path is feasible because orexin receptor antagonists are clinically available. Trials would need actigraphy, polysomnography, plasma/CSF p-tau or Abeta markers, and next-day cognitiv...
