No, TMS and ECT are very different treatments. Electroconvulsive therapy (ECT) or “shock therapy” intentionally causes a seizure. Patients receiving ECT must be sedated with general anesthesia and paralyzed with muscle relaxants. Recovery from an ECT treatment session occurs slowly, and patients are usually closely monitored for minutes to a few hours after treatment.
By contrast, TMS does not induce a seizure and therefore does not require sedation, anesthesia, or muscle relaxants. Patients are able to resume daily activities immediately after a TMS session.

Because TMS uses magnetic pulses, patients are asked to remove any magnetic-sensitive objects (such as jewelry and credit cards). Since TMS produces a loud clicking sound with each pulse, much like an MRI machine, it is recommended patients wear earplugs during treatment for their comfort and hearing protection. Patients are seated during each session of TMS.
During the first TMS session, several measurements are made to ensure that the TMS coil will be properly positioned over the patient’s head. Once this is done, the TMS coil is suspended over the patient’s scalp. The TMS technician then locates the patient’s motor cortex and measures the patient’s motor threshold by administering several brief pulses. The motor threshold is the minimum amount of power necessary to make the patient’s thumb twitch, and varies from individual to individual. Measuring the motor threshold helps the physician personalize the treatment settings and determine the amount of energy required to stimulate an individual patient’s nerve cells in the brain.
Once the motor threshold is determined, the coil is placed above the patient’s treatment area. During the treatment, patients will hear a series of clicking sounds and will feel a tapping sensation on their scalp under the treatment coil.

MS is well-tolerated and is associated with few side-effects. Only a small percentage of patients discontinue treatment because of side-effects. The most common side-effect, which is reported in about half of patients treated with TMS, is headaches. These are mild and generally diminish over the course of the treatment. Over-the-counter pain medication can be used to treat these headaches.

About one third of patients may experience painful scalp sensations or facial twitching with TMS pulses. These tend to diminish over the course of treatment although adjustments can be made immediately in coil positioning and stimulation settings to reduce discomfort.

The TMS machine produces a loud noise, so patients receive earplugs to use during treatment. However, some patients may still complain of hearing problems immediately following treatment. No evidence suggests these effects are permanent if earplugs are worn during the treatment.

The most serious risk of TMS is seizures. However, the risk of a seizure is exceedingly low. In patients not predisposed to seizure either through epilepsy or medication, the risk of seizure is less than 0.5%. While TMS is a safe procedure, it is important to point out that because it is a new treatment, there may be unforeseeable risks that are not currently recognized.
