Patients with OSA or high nocturnal arousal burden may require higher trazodone doses, but OSA is better treated as a covariate than a lead disease-modification hypothesis

Description

OSA-related arousal burden could raise the dose needed for any sleep-mediated neuroprotective effect, perhaps toward 100 mg rather than 50 mg. This is the least supported development hypothesis because it depends on a long causal chain from OSA physiology to biomarker benefit in dementia and is heavily confounded by standard OSA care and endotype heterogeneity.

Dimension Scores

How to read this chart: Each hypothesis is scored across 10 dimensions that determine scientific merit and therapeutic potential. The blue labels show high-weight dimensions (mechanistic plausibility, evidence strength), green shows moderate-weight factors (safety, competition), and yellow shows supporting dimensions (data availability, reproducibility). Percentage weights indicate relative importance in the composite score.

Supporting Evidence 2

Trazodone 100 mg increased arousal threshold in OSA in a small study.
Another crossover study reported reduced AHI with trazodone in OSA.

Opposing Evidence 3

OSA studies were short, small, and not conducted in dementia populations.
One OSA study reduced AHI without significant arousal-threshold change, weakening the proposed mechanism.

CPAP adherence, anatomy, and OSA endotype likely dominate any trazodone effect, limiting strategic value as a lead hypothesis.

How Economics Pricing Works

Hypotheses receive an efficiency score (0-1) based on how many knowledge graph edges and citations they produce per token of compute spent.

High-efficiency hypotheses (score >= 0.8) get a price premium in the market, pulling their price toward $0.580.

Low-efficiency hypotheses (score < 0.6) receive a discount, pulling their price toward $0.420.

Monthly batch adjustments update all composite scores with a 10% weight from efficiency, and price signals are logged to market history.
