TMS Therapy

OVERVIEW

Transcranial Magnetic Stimulation (TMS) is a non-invasive therapeutic treatment that involves the use of an electric pulses to stimulate specific areas of the brain associated with mental health disorders.

Clinical studies have shown the efficacy of TMS in the treatment of a wide array of mental health disorders including major depressive disorder, bipolar disorder, post-traumatic stress disorder (PTSD) and obsessive compulsive disorder (OCD).

TMS is a FDA-approved treatment with only mild or temporary symptoms that can complement current treatment or be used when more conventional methods, such as medication or therapy, haven’t worked.

How TMS Works

TMS is different than medication. Where medication alters the chemistry of the brain, TMS seeks to treat the actual brain circuits involved in the condition.

In a TMS treatment, we place an electric pulse generator against the scalp near the forehead. The repetitive TMS machine (rTMS) emits painless, magnetic pulses that stimulate the nerve cells in the region of the brain associated with the condition. For example, an area of the frontal cortex in patients with depression.

What TMS Treats

In the US, TMS is approved by the U.S. Food and Drug Administration (FDA) to treat three conditions:

It’s also approved to help people to quit smoking.

How Effective is TMS?

Various studies show that at least 60% of people with depression – who haven’t benefited from medication – experience a ‘clinically meaningful response’ with TMS.

For example, in a study of 664 patients with anxious depression, nearly two thirds (65.5%) achieved a successful outcome.

Such success rates have led to TMS becoming the first non-drug, non-invasive treatment to be approved by the FDA, as mentioned earlier.

This does not mean that symptoms are cured. As with lots of mood-disorder treatments, there is a high recurrence rate. But most TMS patients feel better for many months following treatments and opt to come back for further treatment as and when it’s needed.

The TMS Treatment Timeline

TMS treatment varies, but typically takes several weeks at three to five sessions per week. Each session can last between 20 and 50 minutes depending on the device and clinical protocol. FDA-approved protocols for depression differ – they’re every day for six weeks with a total of 30 sessions.

First TMS Treatment

The first treatment can take longer than the rest – up to an hour or so. This is because we need to find the best area to place the magnets and the proper strength needed.

Before the doctor begins this process, called ‘mapping’, patients will be taken to our treatment room where they will relax in a reclining chair and given a set of earplugs to wear during the procedure.

After mapping is complete, the doctor places the rTMS machine against the head. The machine is then turned on and off repeatedly, during which time the patient will hear clicking sounds and feel a gentle tapping sensation. This causes no pain to the patient.

Once mapping is completed, and dosage determined, treatment proceeds as normal.

Subsequent TMS Treatments

Each session follows a similar pattern as before – a comfy chair, ear plugs and a magnetic coil placed around the head followed by clicking sounds and tapping on the forehead as the machine pulses. Again, no pain is caused.

Patients are awake and alert at all times. Once the treatment is completed, the patient can return to normal daily activities such as driving and working.

Expected Outcomes of
TMS Treatment

If treatment is effective, patients should expect depression symptoms to improve or even be completely removed after a few weeks.

As noted earlier, this doesn’t mean symptoms are permanently cured – not enough is known about the future impact TMS can have on depression and mood disorders. However, if patients improve with treatment but then experience further episodes further down the line, treatment can be repeated on an ongoing basis.
