Transcranial magnetic stimulation–associated mania with psychosis: A case report

Transcranial magnetic stimulation (TMS) is a noninvasive procedure used in the treatment of depression. We observed TMS-associated mania with psychotic symptoms in a 55-year-old male diagnosed with MDD and generalized anxiety disorder without history of psychosis or mania. Owing to poor pharmacotherapeutic response and worsening symptomatology, TMS was introduced while continuing phenelzine; this was initially successful in demonstrating positive effects on mood. However, the patient began to develop symptoms consistent with mania with psychosis and was hospitalized. Both TMS and phenelzine were discontinued, leading to significant improvement of the symptoms of mania and psychosis. Phenelzine was later reintroduced for maintenance treatment of depression and anxiety, with no recurrence of mania or psychosis. This case report implicates TMS as a possible cause of mania and psychosis symptoms.
