Depression: What We Know
• Nearly 15 million American adults experience a major depressive disorder (MDD) episode in any given year
• More common in women
– 10-12 million women have MDD each year
• Men less likely to seek treatment
– 6 million men each year develop MDD
• No racial, ethnic, or socioeconomic boundaries
– Life events and environmental factors can trigger an episode or prevent recovery
– Similar to heart disease: genes and biology raise underlying risk
Kessler RC, et al. Archives of General Psychiatry. 2005;62(6):617-627.
Mark – we used this picture before – do you have anything else that works?
The Tangled Web of Depression
• Depression is an independent factor impacting a range of medical conditions and increasing risk of death and hospitalization:– All cause mortality1
– Acute stroke2
– Diabetes3
– Myocardial infarction4
– Cardiovascular disease5
– Congestive heart failure6
– HIV7

The Impact of Depression
• Of the 30,000 people in the U.S. who commit suicide each year, 60 percent have depression
• Increased risk of substance abuse/dependence
• Increased medical co-morbidities
• Strain on interpersonal relationships
• Estimated U.S. economic burden: $83.1 billion in 2000
• World Health Organization reported that MDD is projected to become the second leading cause of disability worldwide by 2020
Carney RM, Freedland KE. Biological Psychiatry. 2003;54(3):241-247.
One Step Forward, One Step Back
• Less stigma & increased awareness by physicians and public
• Antidepressant use has increased steadily in the U.S. in recent years
• Newer medications have fewer severe side effects and better safety profiles – But efficacy continues to be
questioned
• Despite major advances nearly one-third of patients do not experience substantial relief
7
8
The Goals of Treatment
• Acute phase: remission of depression symptoms
– Complete symptom resolution is the goal
• Maintenance phase: Continued response to the treatment over time
– elimination of residual symptoms
– restoration of prior level of functioning
– prevention of recurrence or relapse
Can we realistically get all patients to remission?
Challenge for Remission – Treatment-Resistant Depression
• Roughly 70 percent of people do not achieve an adequate response to their first trial of antidepressant medication
• Four million patients (30 percent) do not achieve adequate response to treatment and/or do not tolerate medication side effects after multiple treatment attempts with different medications
– Considered to be treatment-resistant depression (TRD)

Consequences of of TRD
• Significantly more inpatient hospitalizations, outpatient office visits, and psychotropic medications1,2,3
• Average annual costs ranged from between 2 times greater1 and 6 times greater3 compared to treatment-responsive patients
• Costs >$42K versus only $6.5K for treatment-responsive patients3
• Significantly greater work loss costs (disability and absenteeism) than treatment-responsive patients1
• Increased direct costs of non-remitters include increased medical utilization for non-psychiatric conditions1,2

13
Strategies for Managing TRD
• Current options for treating resistant depression include:– Increasing medication dose or switching to another
antidepressant
– Adding another drug to augment the current medication treatment
– Adding or switching to psychotherapy and/or non-pharmacologic options
14
15
Where Do We Go From Here?
• Available antidepressant medications are effective for a significant number of MDD patients
• However, approximately one-third of MDD patients don’t adequately benefit from, or can’t tolerate, the available antidepressant medications
• Various combinations and augmentation strategies are frequently utilized to treat resistant MDD
– Some evidence-based
– Most empirical
17
Beyond Pills – What are our Options?
• Lifestyle modifications: Exercise, nutrition, environment manipulations
• Psychotherapy
• Biomedical devices
– Electroconvulsive Therapy (ECT)
– Vagus Nerve Stimulation (VNS)
– Transcranial Magnetic Stimulation (TMS) Therapy
18
Electroconvulsive Therapy (ECT)
• Introduced in 1930s
• Most effective depression treatment
• Works by inducing whole brain “seizure” pattern of neural activation through application of direct electrical current to scalp
• Modern ECT is controlled and painless with anesthesia
• Common adverse events: temporary confusion and memory loss
• Long-term cognitive dysfunction possible
Sackeim HA, et al. Neuropsychopharmacology. 2007;32(1):244-254.
19
Vagus Nerve Stimulation (VNS)
• Approved by FDA in 2005 as adjunct to antidepressant medications
• Electrodes implanted on vagus nerve, pulse generator in chest wall
– Indirect stimulation of the brain
• Evidence of efficacy from non-randomized trial
• Invasive procedure required (surgery) with risks from anesthesia
• MRI contraindication
2020
Transcranial Magnetic Stimulation (TMS)
• Application of electromagnetic induction described by Michael Faraday in 1839– Faraday’s Law: a time-varying
magnetic field induces an electric current that runs perpendicular to the time-varying motion of the magnetic field1,2
• Clinical application: Pulsed magnetic fields can induce electrical currents in brain tissues and neurons3

Effect of TMS on the Brain
Acute Effects– Induces electric current
– Depolarizes neurons in superficial cortex
– Leads to local and trans-synaptic changes in brain activity
Example:
Left prefrontal TMS
23 depressed individuals
Activation demonstrated at site of stimulation and also at synaptically connected cortical and subcortical regions

Summary of NeuroStar TMS Therapy Clinical Evidence
31
• Efficacy established in largest multi-site, randomized, sham-controlled TMS clinical trial conducted to date:
– Primary outcome (MADRS): 22.1% reduction in MADRS total score with active NeuroStar TMS vs 9.1% on sham
– Clinically meaningful effect size = 0.52
• In open label extension study, 1 in 2 patients reached response, 1 in 3 patients achieved remission
• In a 6 month, open-label follow up study that allowed TMS reintroduction if needed, <10% of patients experienced relapse of illness
• Safety and tolerability shown to be excellent

Treatment-Resistance Continuum
Independent Research on TMS
• Neuronetics provided NeuroStar devices, but was not involved in study design or implementation
• Tested whether daily left prefrontal rTMS safely and effectively treats MDD– Focus on masking sham conditions
• Well-designed study
– Prospective, multi-site, randomized, active sham-controlled (1:1 randomization)
– 3 weeks of daily weekday treatment followed by continued blinded treatment for up to another 3 weeks in improvers
– Evaluated 199 antidepressant drug-free patients with unipolar, non-psychotic, major depressive disorder
34George et al. Arch Gen Psychiatry 2010; 67(3):507-516.
Confirm # of patients - maybe only 190 actually studied
Confirm # of patients - maybe only 190 actually studied
NIMH Study Findings
• Patients, treaters, and raters effectively masked
• Minimal adverse effects did not differ between active and sham treatment arms
– 88% retention rate (90% sham; 86% active)
• Significant effect of treatment on proportion of remitters (14% active rTMS, 5% sham) (P=0.02)
• Odds of attaining remission 4.2 times greater with active rTMS than sham
– 95% confidence interval, 1.32 – 13.24
• Most remitters had low antidepressant treatment resistance
• Almost 30% of patients remitted in the open-label follow-up
• Conclusion:
Daily left prefrontal rTMS as monotherapy produced statistically significant and clinically meaningful
antidepressant therapeutic effects greater than sham
George et al. Arch Gen Psychiatry 2010; 67(3):507-516.35
NIMH Study Takeaways
• Conducted completely independent of industry
– Used the NeuroStar TMS Therapy system which is the only FDA-cleared device available for the treatment of depression
• Met its a priori primary outcome measure – remission (p=0.02)
• Effect size of treatment benefit is large
– Patients in the active TMS arm had a 4.2 times greater odds of achieving remission
• Included patients with a broad range of treatment resistance
– Patients with one to four prior antidepressant treatment failures were enrolled
36
A Turning Point for My Practice and My Patients
• Changed my practice
• Remarkable success – Even in patients disabled
by depression for years
• Provide TMS therapy exclusively
38
Mark - can we insert some kind of visual to imply a turning point…
Slide is essentially showing how TMS changed the way he practices
What Patients Ask Me
• Will TMS allow me to stop taking medications?
– Simplifies treatment regimen if it does not completely eliminate meds
• Will it bring permanent relief from depression?
– Achieved remission in more than half of patients; infrequently need maintenance therapy
• Is this painful?
– It’s a ‘unique’ experience; never had a pt unable to finish course of treatment; get used to it very quickly; fall asleep after 3-4 tx; oldest patient is 87 who takes a nap;
• How much will this cost?
• Will it change my personality?
39
I’ve included the answers that Lanocha will give, but in presentation, will just list questions, not sub-bullets

Most people are fascinated and want to learn how their brain works
40
Psychotherapy Remains Vital Component of Treatment
• Incorporated into treatment sessions
– Can target behaviors and interpersonal dynamics
• Cognitive-Behavioral Therapy (CBT)
– Focuses on changing negative or irrational thoughts and associated behaviors
– Most validated form of psychotherapy for MDD
• Interpersonal Therapy (IPT)
– Addresses interpersonal issues, relationships
Mark – we used this picture before – do you have anything else that works?
41
How We Decide if TMS is an Option
• Choice of treatment after an initial treatment “failure” depends on many factors, including:– Nature of depressive symptoms
– History of responses to past medication trials
– Medication tolerability
– Side effect profile
– Concurrent medical conditions
– Medication cost
– Likelihood of adherence
– Patient choice
– Physician comfort with managing the treatment
42
TMS Therapy in Clinical Practice
• Non-invasive
• No anesthesia or sedation
• Outpatient procedure easily performed in psychiatrists’ offices
• Approximately 40-minute daily procedure
• 4-6 week treatment course
• Contraindication considerations• Non-removable metallic objects in or
near the head
• Conductive, ferromagnetic, or other magnetic sensitive metals that are implanted or are non-removable within 30 cm of treatment coil
NeuroStar TMS Therapy System User Manual. Neuronetics, Inc: Malvern, PA; 2008.
Quality of Life and Economic Benefits
• NeuroStar TMS shows improvements in standard measures of functional status and quality of life
• When NeuroStar TMS is compared to current standard of care using complex combination antidepressant medications– TMS results in decreased # days lost due to illness, and
increased work productivity,
– TMS results in a net cost savings relative to current pharmaceutical standard of care
