Transcranial Magnetic Stimulation (TMS) The treatment coil produces MRI-strength magnetic field pulses. Magnetic field pulses pass unimpeded through the cranium for 2-3 cm.

1 Transcranial Magnetic Stimulation (TMS) The treatment coil produces MRI-strength magnetic field pulses. Magnetic field pulses pass unimpeded through the cranium for 2-3 cm. and induce a small electric current. Induced electric currents stimulate the firing of nearby neurons, causing the release of neurotransmitters and clinical effects. Faraday (1839) Experimental Research in Electricity.

3 NeuroStar TMS Therapy: Safety Overview No systemic side effects No adverse effect on cognition Most common adverse event associated with treatment was scalp pain or discomfort < 5% of patients discontinued due to adverse events No seizures during clinical studies (over 10,000 treatments) Estimated risk of seizure in post-market use is 0.003% of TMS treatments and 0.1% of patients (based on 100,000 TMS treatments and 3000 patients) Long term safety demonstrated in 6 months follow-up Janicak, P., J.

6 TMS is a New Standard of Care for Depression Following Failure of Initial Treatment Guideline Source Recommendations American Psychiatric Association (2010) World Federation of Societies for Biological Psychiatry (2009) Canadian Network for Mood and Anxiety Treatments (2009) Institute for Clinical Systems Improvement (2010) Acute phase treatment may include pharmacotherapy, depression-focused psychotherapy, the combination of medications and psychotherapy, or other somatic therapies such as electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), or light therapy There is sufficient class I evidence of acute efficacy for TMS in depression in medication-free unipolar depressed patients... Summary Recommendation: There is sufficient Level I evidence of the acute antidepressant efficacy of TMS in the treatment of depression At this time it appears there probably is enough evidence to consider rtms (as implemented with a protocol that utilizes a six-week standardized protocol) an evidence-based treatment for treatment-resistant depression in adults Schlaepfer, et al.

7 Implications of Inadequate Response to MDD Treatment Increased patient care Inpatient hospitalizations, outpatient office visits, and psychotropic medications. 1,2,3 Increased annual costs Average annual costs 2-6 times greater compared to treatment-responsive patients 1,3 Increased work loss costs Significantly greater disability and absenteeism related costs than treatmentresponsive patients 1 Increased costs due to co-morbid care increased medical direct costs of non-remitters include increased medical utilization for non-psychiatric conditions 1,2 1.

9 Optimization of TMS ( OPT-TMS ) Study an independent, NIMH-funded study Major Findings: NIMH-funded, independent of industry N=190 patients, 4 premier academic sites Primary outcome measure met: % Remission - Active 15% vs Sham 4% (P = 0.015); Odds Ratio of achieving remission: 4.2 (95% CI, ) indicates clinical significance Safety confirmed, nearly 90% of patients adherent to acute phase treatment course Conclusion: Daily left prefrontal rtms as monotherapy produced statistically significant and clinically meaningful antidepressant therapeutic effects greater than sham. 9

10 What Does This Mean? Two large, multisite, randomized controlled trials confirmed the clinical significance of TMS as an antidepressant The treatment benefit of TMS over control condition (effect size) compares favorably to those seen with antidepressant medications NeuroStar TMS Therapy is a safe and effective treatment for depression patients who have not benefitted from initial antidepressant medication 10

11 NeuroStar TMS Therapy Clinical Evidence NeuroStar TMS Therapy is an effective, proven approach for major depression when initial treatment fails NeuroStar TMS is now incorporated into expert Practice Guidelines for use following initial treatment failure in patients with major depression NeuroStar TMS is a valuable treatment approach for use in patients who want to reduce medications and the side effect burden that goes along with them 11
