OHSU researchers connect tinnitus with elevated serotonin activity in the brain

 It’s estimated that 1 in 10 adults experience tinnitus, often described as a phantom ringing noise in the ears. The condition can develop due to head trauma, hearing loss, exposure to loud noise or as a side effect of certain medications.   There’s no cure for tinnitus and its origins have long been a mystery. But new research from Oregon Health & Science University has linked tinnitus with elevated serotonin levels in certain regions of the brain. While far from a cure, the discovery could one day help scientists understand how to reverse the condition through brain chemistry.   Larry Trussell is a professor of otolaryngology at OHSU and interim director of the Oregon Hearing Research Center. Angie Garinis is an associate professor of otolaryngology at OHSU and a member of the Oregon Hearing Research Center. She’s also a principal investigator at the National Center for Rehabilitative Auditory Research at the Portland VA.   They both join us to talk about what this new information could mean for patients who suffer from tinnitus.
