Questions and Answers on
Transcranial Magnetic Stimulation (TMS) from
National Alliance on Mental Illness (NAMI)
http://www.nami.org/Content/ContentGroups/Helpline1/Transcranial_Magnetic_Stimulation_(rTMS).htm
What is TMS?
Transcranial magnetic stimulation (TMS) is a
technique for gently stimulating the brain. It
utilizes a specialized electromagnet placed on the
patient’s scalp that generates short magnetic
pulses, roughly the strength of an MRI scanner’s
magnetic field but much more focused. The magnetic
pulses pass easily through the skull just like the
MRI scanner fields do, but because they are short
pulses and not a static field, they can stimulate
the underlying cerebral cortex (brain). Low
frequency (once per second) TMS has been shown to
induce reductions in brain activation while
stimulation at higher frequencies (> 5 pulses per
second) has been shown to increase brain activation.
It has also been shown that these changes can last
for periods of time after stimulation is stopped.
TMS was first developed in 1985, and has been
studied significantly since 1995. TMS is not Vagus
Nerve Stimulation or Acupuncture.
What disorders has TMS been shown to be useful
for?
TMS is currently being investigated as a potential
treatment for patients with major depression,
patients who experience hallucinated "voices" and a
variety of other psychiatric and neurological
disorders. Over 1500 patients have been studied with
TMS. For patients with major depression, many, but
by no means all studies have shown clinical
improvement following TMS. Recent studies that have
used newer technology and stronger stimulation have
shown much improved results. These pilot studies
have taught researchers about how to better use TMS
for depression.
For patients reporting auditory hallucinations
(voices), research has not been as extensive but
initial results have been promising and suggest that
low frequency TMS administered to parts of the brain
underlying speech perception may reduce these
voices.
The Food and Drug Administration has not approved
TMS for any psychiatric treatment at this time.
Therefore TMS is only available as a research
procedure. TMS has been approved in Canada and
Israel as a treatment of depression for patients who
have not responded to medications and who might
ordinarily be considered for a trial of
electroconvulsive therapy (ECT).
What does it feel like to receive TMS?
Generally TMS produces a slight knocking or tapping
sensation on the head. This is also associated with
a tapping sound produced by the TMS device. When
administered at some stimulation sites it can cause
contraction of the muscles of the scalp and
occasionally the jaw. Mild headache and transient
lightheadedness may sometimes result from TMS. These
symptoms usually resolve by themselves shortly after
the treatment is over.
Do you need to get anesthetized for TMS?
No. TMS is an outpatient procedure and does not
require anesthesia or an IV. It can be administered
in a physician’s office or clinic.
Does it hurt?
Approximately 5-10% of patients experience
discomfort at the site of stimulation. In general
this has not been a problem when administering TMS
to patients volunteering for research studies.
How long does a treatment session last?
It depends on the research protocol, but generally
each session takes about a half an hour. One
procedure includes 2 daily sessions approximately 20
minutes each, with a 30-minute break between them.
It is performed for 10 days, with a rest period of 2
days between the first 5 days and the second 5 days.
There are 20 sessions in total.
How many times do you need to receive TMS?
Research protocols vary in the treatment duration,
but most require at least two weeks of daily
stimulation given five times per week, some require
up to 6 weeks.
Are there any side-effects or risks associated
with TMS?
Yes. The main risk of TMS, as with any pulsed
energy, is inducing a seizure,
though with close monitoring this complication has
been very rare. No seizures have been reported in
the scientific literature since safety guidelines
have been implemented. For stimulation at low
frequency (1 to 5 pulses per second) there have been no
reports of seizures. Insofar as the brain is
directly stimulated by TMS, there is a potential
risk of disturbing the brain’s normal functions.
However, in depression studies reported so far,
no
cognitive side-effects like loss of memory, negative
changes in concentration and other cognitive
capacities have been reported. This is in stark
contract to the well known cognitive side effects
associated with electroconvulsive therapy (ECT).
Is TMS widely available to patients in the
U.S. and Canada?
TMS is not yet FDA cleared but has been approved in
Canada and can be purchased from Biophysica.
Why are researchers evaluating TMS?
TMS has some very unique properties. It is
non-invasive, (does not break the skin and can be
delivered in a physician’s office) can easily be
focused on small areas of the brain, and can change
brain activity. This makes it particularly well
suited for treating the brain, while minimizing side
effects typical with other psychiatric treatments
which affect areas of the brain and body not
involved in the disorder.
Specifically for major depression, researchers
understand there are a significant number of
patients suffering from this disorder that are not
helped by the available medications and other
therapies, only receive partial benefit, or are not
able to take medications at all. TMS offers hope
that, if proven effective, many of these patients
may be able to experience symptom relief.

Research on Transcranial
Magnetic Stimulation
November 27 , 2007 Penn
Research Shows Transcranial Magnetic Stimulation
Effective in Treating Major Depression
Non-drug, non-invasive treatment helps patients
who have tried other options without success
PHILADELPHIA – Researchers at
the University of Pennsylvania School of
Medicine and other study sites have found that
transcranial magnetic stimulation (TMS) – a
non-invasive technique that excites neurons in
the brain via magnetic pulses passed through the
scalp – is a safe and effective, non-drug
treatment with minimal side effects for patients
with major depression who have tried other
treatment options without benefit.
This study – the largest
to-date studying TMS as a standalone treatment
for major depression – appears in the December
1st issue of Biological Psychiatry.
TMS provides a well-tolerated
treatment option to patients whose depression is
otherwise treatment resistant,” says
John P. O’Reardon, MD, Associate
Professor of Psychiatry at Penn, and lead study
author. “Since TMS is administered via the
scalp and therefore goes directly to the brain,
it allows the patient to avoid bodily side
effects such as weight gain, sedation and/or
sexual function.”
The study was conducted at 23
sites in the U.S., Australia, and Canada, and
involved 301 medication-free patients with major
depression who had not benefited from prior
treatment. The patients were randomized to
active or sham TMS for 4-6 weeks. Response and
remission rates with active TMS were
approximately twice those of sham.
Additionally, there were no unexpected, serious
side effects, and less than 5% of patients
discontinued their TMS due to side effects.
This is about three times better tolerated and
safer than standard medications, which have
about a 15% discontinuation rate due to side
effects.
Dr. O’Reardon further
comments, “As indicated by recent large scale,
government-sponsored, studies of existing
treatment options for major depression conducted
by the National Institute of Health (the STAR-D
reports), there is a great need to develop new,
effective treatments for patients, especially
those not benefiting from first line
interventions. The results of this study
indicate that TMS offers new hope to patients in
this regard.”

Magnetic Stimulation Therapy
Effective for Treatment-Resistant Depression: can beat depression when
medication and therapy haven’t worked, according to the December issue
of Mayo Clinic Health Letter. Dec 2009
The therapy, called transcranial magnetic
stimulation (TMS), involves using brief powerful electromagnetic pulses
to alter brain activity. The U.S. Food and Drug Administration (FDA) has
approved the therapy for patients whose depression hasn’t improved with
medications - estimated to be from 10 to 20 percent of those with the
illness.
Patients treated with TMS may experience total remission of depression
symptoms. A 50 percent improvement in depression symptoms is common.
A typical treatment schedule involves five, one-hour sessions a week for
at least three to five weeks. During a session, the patient sits in a
reclining chair while the magnetic coil is positioned and activated.
Patients remain awake and alert as the coil alters brain activity. No
anesthesia or invasive procedures are used. The benefits gradually
emerge over several weeks.
A recent study compared TMS therapy in a group of people who had
drug-resistant depression to a matched group of patients who received an
inactive placebo form of TMS therapy. After four to six weeks, the TMS
group was twice as likely to have remission of depression symptoms as
the group receiving the placebo treatment.
While TMS is being used to treat depression at select medical centers,
there are still many unknowns. Researchers don’t know how long the
benefits might last. The general belief is that most patients who
improve with TMS will continue to need some ongoing therapy for
depression, whether it’s medication, counseling, additional TMS sessions
or some combination of these therapies.
