Tinnitus remains an enigma, with no consensus on the pathophysiology or treatment of this condition. Transcranial magnetic stimulation has recently emerged as a possible treatment modality that has shown some promise. The paper by Plewnia et al,¹ (see p 152) reported on the efficacy of delivering 10 sessions of low-frequency repetitive transcranial magnetic stimulation (rTMS) over the temporoparietal association cortex to treat chronic tinnitus. Although rTMS is known to effect change in tinnitus perception,^2–4 it is unclear how this change occurs and what method of application is most effective. Plewnia et al¹ provide new information with implications for possible future clinical use. In contrast with previous studies,³ Plewnia et al show only a temporary effect of rTMS on tinnitus, at least with currently used treatment schedules. The study also highlights the fact that blood flow asymmetries associated with tinnitus, and commonly used to target rTMS, . . . [Full text of this article]
