Repetitive Transcranial Magnetic Stimulation Used For Tinnitus Suppression: A Voxel-Based Morphometry Study, Lauren E. Laitman

Honors Theses

Tinnitus is a debilitating disorder with unknown underlying mechanisms, often induced by loud noises. Tinnitus symptoms include the conscious perception of constant sound absent an external source. This study sought to determine effectiveness of treatment with repetitive transcranial magnetic stimulation (rTMS), and to use voxel-based morphometry (VBM) to identify treatment related neuronal reorganization. One hertz rTMS was delivered for 20 minutes on each of 5 consecutive days. Tinnitus suppression was measured with the Tinnitus Handicap Questionnaire (THQ), and VBM was carried out on structural Magnetic Resonance images collected before and after sham-treatment and rTMS. Findings indicate the effectiveness of rTMS …
