Transcranial Magnetic Stimulation (TMS) a real alternative for Major Depression Disorder
Dr Jason Pace What is Transcranial Magnetic Stimulation ?
TMS technology was invented in 1985. Consists of a coil which is placed on a persons head and applies a pulsating magnetic energy to the cerebral cortex This subsequently induces electrical activity in the brain. rTMS is when TMS is delivered in a repeated sequence of pulsing magnetic energy that is applied for the treatment.
While is comes from the school of brain stimulation, unlike ECT treatment, TMS does not involve inducing seizures and is administered to patients in an outpatient setting while fully awake and does not cause any cognitive impairment. What does rTMS treatment involve?
An initial planning session to creates a customised treatment plan for the patient.
Subsequent sessions last about 40 minutes. rTMS needs to be given at least 3 times a week.
Treatment for acute depression requires 30 sessions.
TMS can be given while patient are still taking medication.
rTMS tolerability Typically patient experience some discomfort in the scalp locally over the treatment area. This may cause a mild headache post treatment.
Despite some discomfort, patients rates rTMS as a very well tolerable and acceptable procedure. Studies show very few drop outs and clinically compliance is excellent.
No systemic side effects.
Very low risk of seizure.
Who is a good candidate for rTMS ?
TGA guidelines recommends - Treatment Resistant Depressive disorder
Consider prior to ECT
Consider if tolerating medication has been a problems

TMS for TRD is equally effective in patient >65yr. (Conelea et al Journal of Affective Disorders, Aug 2017)
Effectiveness of TMS
Carpenter et al.(Depress Anxiety 2012) in a multisite naturalistic study involving 307 patient from 42 clinics demonstrated 58% response rate and 37% remission rates, with the average patient receiving 28 treatment sessions.
Antidepressant effect of TMS is independent of medication, a meta-analysis of 54 sham-controlled studies published between 1997–2013 (Kedzior et al, Neuropsychiatr Dis Treat. 2014).
Over 15 meta-analyses of TMS for depression, including more recent randomised control studies all consistently show statistically significant efficacy. ( Perera et al, Brain Stimulation 9 (2016)
TGA approved 2007, FDA approved 2008, RANZCP guidelines endorsed 2013, NICE indorsed 2016.
Long Term Benefits of TMS
Multisite, naturalistic observational study, shows improvement in depressive symptoms following a course of rTMS, was maintained over the 12 month period for both responders and remitters. (Dunner , Sackeim, Carpenter et al J Clin Psychiatry 2014).
Philip et al (Brain Stimulation 2016) showed that 70% of patients having benefited from TMS remained well 12 months. More importantly 70% of patient that relapsed, responded as well and quicker to a retreatment with TMS. This suggests TMS can be potentially useful in maintenances treatment. Sydney TMS

Accepting referrals for GPs and Psychiatrists for TRD patients only over 18yrs.
Our Observation
Mean age of 45.09 , Range 18-90 yrs
Sex 59% male , 41% female.
All Patients met diagnosis of Treatment resistant Major Depressive Disorder ( failed two adequate trails of medications)
Average number of TMS sessions - 28
In addition to clinical observations we also conduct baseline and repeated HAM-D and MADRS ( every 10 sessions) mean HAM-D pre treatment score 16.13 (SD=7.32) mean MADRS pre treatment score 26.15 (SD=10.75). Outcomes so far.
Analyses using SPSS was performed on data from 54 patients who completed at least 20 sessions. The level of statistical significance was set at p .05
Response – was defined as a 50% reduction in scores
Remission -was defined as HAMD (total score ≤7) and MADRS (total score ≤9)
Response or Remission 50% Response rate 41% Remission rates 28%
These results reached statistically significance even with only 54 patient.
Where to next for TMS treatment ?
“Theta Burst “a new ultra high frequently TMS that is looking promising and reduces treatment times to 10 minutes so could reduce costs of treatment.
More evidence is emerging regards safety of offering patients sessions in shorter intervals, eg 2-3 sessions daily safely.
Other Conditions ;
OCD - Kumar et al , Neuropsychiatry (London) (2016)
Addictions- Gorelick et al Ann N Y Acad Sci. 2014 Oct
Schizophrenia – Cochrane Review 2015- some evidence in reducing auditory hallucinations but generally quality of research is poor.
Others…ADHD, Tourettes, Austism… very early work only
Take Home…….
TMS is NOT an experimental treatment, it is a Real treatment option and with over 20 years of research and international governing body endorsement,
TRD = should consider TMS rather than ongoing medication trial and certainly prior to ECT
TMS is not only good in acute treatment but maybe most useful as maintenance treatment for patient with chronic depression
Patient tolerability and acceptance of TMS is excellent.

The results of this first randomized controlled study of DBS for the treatment of TRD did not demonstrate a significant difference in response rates between the active and control groups at the end of the 16-week controlled phase. However, a range of 20% to 26.7% of patients did achieve response at any time during the open-label continuation phase

DBS is a well-established procedure for the treatment of advanced movement disorders, such as Parkinson’s disease, tremor and dystonia. It has also been used in the control of the movement disorder associated with severe and medically intractable Tourette syndrome.
Current research and clinical trials into the use of DBS to treat psychiatric disorders such as OCD, depression, substance use disorders, and anorexia are slowly occurring worldwide. It has been approved by the Food and Drug Administration for OCD treatment in the US but is still considered an experimental treatment for this disorder in most countries.
Whilst further research and clinical trials are required to develop a substantial body of evidence to support efficacy and safety of DBS to treat psychiatric disorders, there is evidence to suggest that it may play a role in the treatment of a select group of patients with severe / treatment resistant psychiatric disorders in the future.
Its use in psychiatric disorders should be considered experimental at this time and only be applied in the context of appropriately developed and human research and ethics committee approved clinical studies. Avoiding the errors of Psychosurgery

What is EEG?
Electroencephalography... EEG is often used to diagnose ... is a process used to image the brain while at seizures or check for changes in rest or is performing a cognitive task. consciousness
EEG can also be used:
in the clinical assessment of clients to guide therapeutic interventions
as an outcome measure – to evaluate
efficacy of therapy
CLINICAL WORK: EEG for Assessment and Outcomes Measurement 4 How do we record EEG
Electroencephalography is a simple, painless and completely safe procedure. The brain electrical activity is recorded by multiple sensors placed on the scalp.
The sensors are attached to the amplifier that enhances the electrical signals captured on the surface of the scalp. This signal is further analysed by a specially designed computer program.
5 CLINICAL WORK: EEG for Assessment and Outcomes Measurement The EEG reflects brain states
Brain waves arise from synchronised activation of many neurons. This is how different areas of the brain communicate with each other and how the brain communicates with the rest of the body.
Slower brain waves (Delta, Theta and Alpha) indicate lower level of activity, idling or sleep
Faster brain waves (Beta, High Beta, Gamma) indicate high level of activity
An EEG reading indicates which parts of the brain are functioning properly and which are not.

EEG is used at STARTTS for assessment of clients
To discern possible causes of problems (such as headaches, memory loss or attentional difficulties)
To determine which therapeutic interventions may be appropriate with complex cases
To determine if neurofeedback is an appropriate intervention, and to guide the intervention

Case 2: Use of EEG to investigate the possible cause of memory difficulties in a client presenting with PTSD symptoms in order to make a decision about appropriate intervention (38 y.o. male)
Faster alpha brain-wave activity is suggestive of the sympathetic nervous system overarousal frequently seen in PTSD. Poor working memory could be a result of a high level of arousal, rather than specific brain dysfunction. Deep relaxation exercises could be recommended.
