This document provides information about a presentation given by Dr. Louis B. Cady on transcranial magnetic stimulation (TMS) as a treatment for depression. It begins with Dr. Cady's credentials and commercial disclosure stating he has received honoraria from several companies but that this presentation is not being underwritten by any company. The presentation then covers how TMS works, its safety and effectiveness compared to antidepressant medications and electroconvulsive therapy (ECT), and its inclusion in treatment guidelines for depression.

10. 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

17. A quick look back in history
The Interpretation of
Dreams – 1885 - 1890
Ugo Cerletti 1935
Prozac - 1987
19. 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
20. "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.”
21. But even before these guys…
• Electromagnetic
induction – 1831
(Faraday & Joseph
Henry)
• 1st demonstrated by
Faraday August 29,
1831
22. 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.

and vertigo” induced inside
powerful magnetic coil

26. 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

31. An unusual side effect
of imaging (2004)…
• 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.”
32.
33. 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
34. 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
Dorsolateral
prefrontal
cortex
Anterior
cingulate
cortex
Kito (2008) J Neuropsychiatry Clin Neurosci
These effects are
associated with
improvements in
depressive
symptoms
35. • TMS uses Faraday’s principle of magnetic
induction to:
– Induce a current flow and depolarization in
“local” neurons close to the TMS Coil, and
– It also induces, by additional synaptic pathways,
release of neurotransmitters diffusely in the
brain from deep brain nuclei
• Choose one:
– TRUE
– FALSE
Question 2
36. ECT vs. TMS
ECT TMS
Anesthesia, LOC Yes No
Induction of seizure Yes No
Systemic effects Anesthetic drugs,
increase HR
none
Treatment schedule 3X/ week (8 -15 tx) Daily, M-F, six weeks (30
tx)
Rapidity of onset 2 – 3 treatments 2 – 3 weeks
Mechanism of action SEIZURE. Massive NT
release; rise in sz

Reactivation of neural
circuits. Precise, LOCAL
release of NT’s.

37. Identify which of these statements are true:
a)ECT induces seizures; TMS does not.
b) There is systemic exposure to drugs with ECT;
there is none for TMS.
c)ECT causes memory loss/confusion; TMS does
not
d)ECT is well reimbursed by insurance; TMS is not
yet well reimbursed.
ANSWERS:
1)All are true
2)Not all of these statements are true.

42. 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

43. • In the original registration study for TMS:
– There were multiple failed medications trials in
these patients (average of four)
– 1 out of 2 patients responded
– 1 out of 3 patients remitted
– The effect size of the treatment was roughly 0.5
• Choose one:
– All of the previous statements are TRUE
– Not all of the previous statements are true
Question 4
44. 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.”

45. 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….”

– Average HAM-D decrease in depressive symptoms >5
points vs. sham control
• Meets clinical significance threshold of 3 points on the HAM-D

• 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

• Appears to be at least as effective as ECT for treatment
and relapse prevention
Summary of Clinical Outcomes
