Hypnotic Resistance in Insomnia: How Common It Is and What Increases Risk

Official title: Hypnotic Resistance: Definitions, Prevalence, and Risk Factors

Funded at Mayo Clinic Rochester · NIH-11445263 · Data updated 2026-11-12

This NIH grant explores why some people with insomnia don’t respond to hypnotic meds and what factors, including genetics, predict this resistance.

Who could benefit from this research

Could help

Patients with chronic insomnia who have been treated with hypnotics and have or are at risk of treatment resistance.

Less likely to help

Patients who achieve complete response to hypnotics or who do not meet TRI definitions may not see direct benefit.

What this research studies

The project uses real-world patient data from Mayo Clinic sources to define and measure how often treatment-resistant insomnia occurs. It will review electronic health records to refine definitions and confirm them by chart review. Researchers will look for clinical and demographic risk factors and build a predictive model to identify who is at higher risk for TRI. They will also investigate the genetic underpinnings of TRI using genome-wide studies and meta-analysis to see how genetics may influence treatment response.

Why it matters

Potential benefit: If successful, clinicians could better identify patients at risk for TRI and tailor treatments or prevention strategies accordingly.

How similar studies have gone: Prior work suggests a complex mix of clinical, demographic, and genetic factors in treatment response, but TRI definitions and predictive models are still being refined.
