Chronic tinnitus is a prevalent and disabling condition that is frequently accompanied by domain-specific cognitive difficulties. Abnormal neural oscillations and disrupted cross-frequency coupling (CFC) have been implicated in its pathophysiology....

Promising but preliminary — await full published results before considering tACS as a clinical tool for tinnitus; no practice change warranted yet.
Individualized phase-amplitude-coupled tACS represents a novel, non-invasive neuromodulation approach for chronic tinnitus that, if effective, could expand treatment options beyond current standard care.
- 01RCT-style study tests individualized phase-amplitude-coupled tACS for chronic tinnitus.
- 02Stimulation parameters were personalized to each participant's brain rhythms.
- 03Outcomes include both tinnitus severity and associated cognitive difficulties.
- 04Published in Frontiers in Neuroscience.
- 05Non-invasive neuromodulation for tinnitus remains an active and evolving research area.
Individualized phase-amplitude-coupled tACS can reduce chronic tinnitus severity.
studyuncleartACS tuned to individual brain wave patterns can improve cognitive difficulties associated with tinnitus.
