Patients with severe major depression most commonly undergo electroconvulsive therapy (ECT). Although this procedure is usually safe and the complication rates are very low, some side-effects and medical complications are observed. The reported adverse effects are generally minor in severity, and vertigo is one of these complications. We presented a case of benign paroxysmal positional vertigo (BPPV) occurring after ECT and aimed to discuss the pathophysiological mechanism of this condition. To the best of our knowledge, there are no other case reports regarding the co-occurrence.
