Depression—Impact on the Healthcare System

• Compared with those without depression, depressed individuals: – Utilize all types of healthcare services more

often

– Incur 1½ to 2 times greater healthcare costs

– increased length of hospital stay

– significant worsening of physical, social, and role functioning

A quick look back in history

The Interpretation of Dreams – 1885 - 1890

Ugo Cerletti 1935Prozac - 1987

ShrinkingShocking

or Drugging

[Supposedly] the only three things you could do to a patient’s

brain…]

The Therapeutic Trifecta of Psychiatry:

ECT – origins• Origin in 1700’s – Middlesex Hospital

– machine with weak electrical current used for range of illnesses.– John Birch, English neurosurgeon, used it to shock the brains of

depressed patients– Benjamin Franklin, after shocked, recommended electric shock for

tx of mental illness

• Ugo Cerletti – 1935 – noted (incorrectly) that epilepsy and schizophrenia didn’t occur in same patient

• Problems with ECT – memory loss, anesthesia risk• Cost of $6400 for eight treatments• 80% improvement • 33,000 hospitalized Americans – ECT in 1980, last year for

NIMH figures– http://www.faqs.org/health/topics/19/Electroconvulsive-therapy.html

"The Shock Shop, Mr. McMurphy, might be said to do the work of the sleeping pill, the electric chair and the torture rack. It's a clever little procedure, simple, quick, nearly painless it happens so fast, but no one ever wants another one. Ever.”

But even before these guys…

• Electromagnetic induction – 1831 (Faraday & Joseph Henry)

• 1st demonstrated by Faraday August 29, 1831

Faraday’s law• “The induced electromotive force (EMF) in

any closed circuit is equal to the time rate of change of the magnetic flux through the circuit.”

• Discovered by Michael Faraday and Joseph Henry in 1831 – Faraday first to publish.

(exposed cortex) of patient with cranial defect.

• d’Arsonval – “Phosphenes and vertigo” induced inside powerful magnetic coil

• Silvanus P. Thomson, Ph.D. – new type of magnetic stimulation (1910)

Thompson, SP. “A Physiological Effect of an Alternating Magnetic Field.” Proceedings of the Royal Society of London B82:396-399, 1910

First patent application for magnetic therapy:

• 1902 Adrian Pollacsek and Berthold Beer – Vienna, Austria for a “therapeutical apparatus”

• Electromagnetic coil, placed over the skull was noted to “pass vibrations into the skull” and “treat depression and neuroses.”

First modern TMS:

• Barker AT, et al. “Non-invasive magnetic stimulation of the human motor cortex. The Lancet 1:1106-1107, 1985.

• CONCLUSIONS: “These preliminary data suggest that the EP-MRSI scan induces electric field that are associated with reported mood improvement in subjects with bipolar disorder.”

Neuron

TMS Directly Depolarizes Cortical Neurons

Pulsed magnetic fields from TMS: •induce a local electric current in the cortex which depolarizes neurons •eliciting action potentials•causing the release of chemical neurotransmitters

Neurons are “electrochemical

cells” and respond to either electrical or

chemical stimulation

TMS Releases Neurotransmitters in the Brain

Depolarization of neurons in the DLPFC causes local neurotransmitter release

Depolarization of pyramidal neurons in the DLPFC also

causes neurotransmitter release in deeper brain neurons

Activation of deeper brain neurons then exerts secondary effects on remaining portions of

targeted mood circuits

Who Was Studied?• Primary diagnosis: DSM-IV Major Depressive

Disorder– Unipolar type, non-psychotic– Moderate to severe symptoms at baseline– Approximately one-third of patients had a co-morbid anxiety

disorder (OCD excluded)

• Antidepressant Treatment History:– Average number of antidepressant medication trials in current

episode = 4 (range: 1 to 23 attempts)• Majority of treatment attempts were unable to achieve adequate

dose and duration of treatment due to intolerance

– all patients had failed to achieve satisfactory benefit from one antidepressant medication at an adequate dose and duration in current episode

Demitrack and Thase (2009) Psychopharm Bulletin

Optimization of TMS (‘OPT-TMS’) Study

• NIMH-funded, independent of industry • N=190 patients, 4 premier academic sites • Primary outcome measure: % Remission - Active 15% vs Sham 4% (P =

0.015); Odds Ratio of achieving remission: 4.2 (95%CI, 1.3-13.2)

Major Findings:• MADRS total score decreased:16.6%

(Active) vs 6.9% (Sham) p=0.01 (Effect size: 0.51)

• 30% of patients achieved remission in open-label extension phase

• Excellent safety and adherence

Conclusion: “Daily left prefrontal rTMS as monotherapy produced statistically significant and clinically meaningful antidepressant therapeutic effects greater than sham.”

Recent TMS Literature Review• Roughly 30 controlled clinical research studies to date• Most recent meta-analysis (Slotema, et al, 2010):

– Included analysis of 34 studies involving 1,383 patients– Estimated standardized effect size = 0.55 (P < 0.001)

Conclusion: “…rTMS deserves a place in the standard toolbox of psychiatric treatment methods, as it is effective for depression…and has a mild side effect profile….”

Relapse Rate among those patients in remission at entry into long term follow up

• In research settings, two large, multisite, randomized controlled trials demonstrated clinically significant antidepressant effect of TMS

• Prospective, naturalistic study confirms these results in real-world practice settings

• Overall, 1 in 2 patients respond and 1 in 3 patients achieve remission

• Meta-analyses from multiple studies shows TMS effect size of >0.5

• High level of treatment adherence , >80% of patients completed acute treatment in both research setting and in clinical practice

• Appears to be at least as effective as ECT for treatment and relapse prevention

Safety and Tolerability of NeuroStar TMS

Therapy

• 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 with NeuroStar device during clinical studies (over 10,000 treatments)

• Rare risk of seizure with NeuroStar TMS in post-market use (0.003% per treatment, <0.1% per acute treatment course) (>150,000 treatments in post-marketing experience to date)

• Long term safety demonstrated in 6 months follow-up
