Advancing Misophonia Research: Understanding, Diagnosis, and Treatment
Misophonia is a disorder of emotion processing in which ordinary day-to-day sounds cause distress to the point that it has debilitating effects on the occupational, social, and domestic life of the sufferer. Understanding the psychological factors underlying misophonia is crucial for developing effective treatments and improving the quality of life for those affected.
Brain Imaging Study at the University of Iowa
Researchers in the Interoception Lab at the University of Iowa are conducting a brain imaging study to understand how the brain processes common sounds that we hear on a daily basis.
Participants are asked to complete questionnaires (approximately 20 minutes). If eligible, an MRI brain scanning session lasting 1 hour will be arranged. Participants will be paid $10 for completing the questionnaires and an additional $20 for the MRI scanning.
Key Findings from Misophonia Research
One project served an important role in the research on misophonia by allowing researchers to understand what happens in the brain and body of misophones while hearing a trigger sound. Specifically, Kumar et al. used fMRI, MRI, and physiological measurements to examine trigger-related responses in the brain and body. This project investigated the role that the mirror neuron system has in misophonia responses, given that most trigger sounds are produced by orofacial movements. Resting state fMRI and sound-evoked fMRI responses were analyzed.
Misophonia subjects compared to control subjects showed:
- Stronger resting-state fMRI connectivity between auditory/visual cortex with the ventral premotor cortex (related to orofacial movements).
- Stronger connectivity between the auditory cortex and orofacial motor area.
- Stronger activation in the orofacial motor area in response to trigger sounds.
Brain regions implicated in misophonia, including auditory cortex and motor areas.
Funding Priorities and Goals for Misophonia Research
The Misophonia Research Fund has identified four broad scientific areas where there is potential for high-impact advances in the science and treatment development for misophonia:
- Focus on interdisciplinary science and collaboration
- Build a fundamental understanding of misophonia
- Support the development of diagnostic tools
- Drive increased rigor in misophonia clinical studies
The Misophonia Research Fund intends to fund research projects aimed at better understanding misophonia, characterizing symptomatology and associated impairments, and assessing interventional strategies to treat those with the disorder.
Misophonia Research Funding Opportunities
The Misophonia Research Fund offers several funding opportunities to support innovative research in the field:
- Misophonia Research Impact Award: Up to $500,000 USD for investigator research grants across 2-3 years and up to $200,000 USD for postdoctoral research grants across 2-3 years.
- Misophonia Data Discovery Award: Up to $75,000 USD for graduate students, postdoctoral fellows, and independent investigators across 1-2 years.
- Misophonia Research Consortium Award: Up to $1,500,000 USD for teams of two or more independent investigators engaged in team science.
RFPs are open for the Misophonia Research Impact Award, the Misophonia Data Discovery Award, and the Misophonia Research Consortium Award.
