Transcranial brain stimulation for the treatment of tinnitus: Positive lessons from a negative trial
Tinnitus impairs many people's quality of life. The treatment of these patients is often a major challenge for general physicians, otolaryngologists, and psychiatrists particularly since reliably effective therapeutic tools are virtually not available. This not the least because the knowledge about its pathophysiology is still fragmentary. In search of the origins of tinnitus, early functional imaging studies have expanded the focus of tinnitus research to the brain. They supported the notion that this auditory phantom perception is associated with hyperactivity in primary and higher-order auditory processing areas.
