How to talk to patients and families about TMS
Brain stimulation often is used for treatment-resistant depression when medications and psychotherapy are not enough to elicit a meaningful response. It is both old and new again: electroconvulsive therapy (ECT) has been used for decades, while emerging technologies, such as transcranial magnetic stimulation (TMS), are gaining acceptance.
Patients and families often arrive at the office with fears and assumptions about these types of treatments, which should be discussed openly. There are also differences between these treatment approaches that can be discussed.
The field of non-invasive brain stimulation—in particular, TMS—faces a different set of complex issues to navigate. Because TMS is relatively new (approved by the FDA in 2008 for treatment-resistant depression),3 patients and families might believe that TMS may be more effective than ECT, which has not been demonstrated.4 It is important to communicate that:
-
Although TMS is a FDA-approved treatment that has helped many patients with treatment-resistant depression, ECT remains the clinical treatment of choice for severe depression.
-
Among antidepressant non-responders who had stopped all other antidepressant treatment, 44% of those who received deep TMS responded to treatment after 16 weeks, compared with 26% who received sham treatment.5
-
Most patients usually require TMS for 4 to 6 weeks, 5 days a week, before beginning a taper phase.
-
TMS has few side effects (headache being the most common); serious adverse effects (seizures, mania) have been reported but are rare.3
-
Patients usually are able to continue their daily life and other outpatient treatments without the restrictions often placed on patients receiving ECT.
-
If the patient responded to ECT in the past but could not tolerate adverse cognitive effects, TMS might be a better choice than other treatments.
