Sex-specific pathways of sympathetic dysregulation in TMD and related pain disorders

Official title: Sex-specific Mechanisms of Sympathetic Dysregulation in TMD and Comorbid Pain Disorders

Funded at University of California Los Angeles · NIH-11600905 · Data updated 2026-11-12

This study looks at how stress-driven signals in the nervous system may worsen jaw pain and related conditions, especially in women, to find why some people develop stronger pain and tissue changes.

Who could benefit from this research

Could help

Adults with painful TMD, with or without multisite chronic pain conditions, and demographically comparable controls.

Less likely to help

Healthy individuals without TMD or chronic pain may participate in control groups but are unlikely to benefit directly.

What this research studies

Researchers at UCLA will observe people with painful temporomandibular disorder (TMD) and comparable controls to see how stress, the autonomic nervous system, and sex influence pain and tissue changes. They will examine how sympathetic activity connects with brain and musculoskeletal changes, inflammation, and neuroplasticity. The project uses surveys, clinical assessments, imaging, and biological samples to map pathways from stress to pain. Results could clarify who is at risk and point to targeted treatments that address nervous system regulation and sex-specific factors.

Why it matters

Potential benefit: If successful, the work could lead to personalized strategies that reduce jaw pain by correcting autonomic nervous system imbalances, especially in women.

How similar studies have gone: Prior research supports links between stress, autonomic regulation, and chronic pain, with some evidence of sex-specific effects.
