  "description": "The authors explicitly state that studies manipulating orexin-A levels are needed to confirm its causal role in AD pathophysiology. Without direct manipulation experiments, the therapeutic potential remains speculative despite promising correlative evidence.\n\nGap type: open_question\nSource paper: Orexin-A and Circadian Disruption in Alzheimer's Disease: Implications for Amyloid-Beta Pathology.

  "resolution_criteria": "Resolution requires: (1) orexin-A dosing study in AD/ circadian disorder mouse models measuring cognitive outcomes (Morris water maze, novel object recognition) vs circadian rhythm (locomotor activity, body temperature); (2) mechanistic study showing whether cognitive rescue is dependent on orexin receptor signaling and circadian alignment; (3) dose-response establishing whether timing of administration matters for efficacy. Simple behavioral improvement without mechanistic understanding is insufficient.",
