Can ketamine silence the ringing? new study tests a surprising treatment for tinnitus

This study tested whether ketamine, a drug that blocks certain brain signals, can help people with tinnitus (ringing in the ears). 42 adults with chronic tinnitus received both ketamine and a placebo on different days. Researchers used brain scans to measure changes in brain chemicals linked to tinnitus. The goal was to see if ketamine could reduce tinnitus distress, especially in those who also feel anxious or depressed.
