Background Prefrontal Transcranial Magnetic Stimulation (TMS) therapy repeated daily over 4–6 weeks (20–30 sessions) is US Food and Drug Administration (FDA) approved for treating Major Depressive Disorder in adults who have not responded to prior antidepressant medications. In 2011, leading TMS clinical providers and researchers created the Clinical TMS Society (cTMSs) (www.clinicaltmssociety.org, Greenwich, CT, USA), incorporated in 2013. Methods This consensus review was written by cTMSs leaders, informed by membership polls, and approved by the governing board. It summarizes current evidence for the safety and efficacy of the use of TMS therapy for treating depression in routine clinical practice. Authors systematically reviewed the published TMS antidepressant therapy clinical trials. Studies were then assessed and graded on their strength of evidence using the Levels of Evidence framework published by the University of Oxford Centre for Evidence Based Medicine. The authors then summarize essentials for using TMS therapy in routine clinical practice settings derived from discussions and polls of cTMSs members. Finally, each summary clinical recommendation is presented with the substantiating peer-reviewed, published evidence supporting that recommendation. When the current published clinical trial evidence was insufficient or incomplete, expert opinion was included when sufficient consensus was available from experienced clinician users among the membership of the cTMSs, who were polled at the Annual Meetings in 2014 and 2015. Conclusions Daily left prefrontal TMS has substantial evidence of efficacy and safety for treating the acute phase of depression in patients who are treatment resistant or intolerant. Following the clinical recommendations in this document should result in continued safe and effective use of this exciting new treatment modality.

Outcomes demonstrated response and adherence rates similar to research populations. These data indicate that TMS is an effective treatment for those unable to benefit from initial antidepressant medication.

There are no rapid-acting intramuscular formulations of atypical antipsychotics available for quickly calming an agitated patient with bipolar disorder. In this study, 201 agitated patients with bipolar mania were randomly assigned to receive one to three injections of the atypical antipsychotic olanzapine (10 mg, first two injections; 5 mg, third injection), the benzodiazepine lorazepam (2 mg, first two injections; 1 mg, third injection), or placebo (placebo, first two injections; olanzapine, 10 mg, third injection) within a 24-hour period. Agitation was measured at baseline, every 30 minutes for the first 2 hours, and at 24 hours after the first injection using the Positive and Negative Syndrome Scale-Excited Component subscale and two additional agitation scales. At 2 hours after the first injection, patients treated with olanzapine showed a significantly greater reduction in scores on all agitation scales compared with patients treated with either placebo or lorazepam. At 24 hours after the first injection, olanzapine remained statistically superior to placebo in reducing agitation in patients with acute mania, whereas patients treated with lorazepam were not significantly different from those treated with placebo or olanzapine. Furthermore, no significant differences among the three treatment groups were observed in safety measures, including treatment-emergent extrapyramidal symptoms, the incidence of acute dystonia, or QTc interval changes. These findings suggest that intramuscular olanzapine is a safe and effective treatment for reducing acute agitation in patients with bipolar mania.
