Transcranial Magnetic Stimulation (TMS) at Cambridge Biotherapies

TMS works by using precisely targeted magnetic pulses to stimulate or inhibit specific areas of the brain where symptoms of depression and anxiety originate. Some pulses are designed to activate certain brain areas. For example, activating pulses would be used to treat patients who feel lethargy and hopelessness. Protocols designed to quiet down overactive areas might be used for patients who suffer with anxiety and obsessive-compulsive disorder. With multiple treatments, many people can achieve remission from depression and anxiety in a matter of weeks.

At Cambridge Biotherapies, we provide consultation to both patients and clinicians, and work collaboratively with outside treaters.

In addition to standard TMS, which is offered by other treatment centers and hospitals in the Boston area, we offer a new, FDA-approved protocol called Theta Burst. While standard TMS requires 20 minutes per treatment, Theta Burst requires only 1 to 3 minutes per treatment. Furthermore, ongoing research is demonstrating that Theta Burst may be even more effective than standard TMS protocols.

During a TMS treatment you will be seated in a comfortable chair, and a small cotton cap will be placed on your head. The TMS therapist will then conduct a “mapping” session to determine the ideal areas for treatment. During this mapping session you will feel a tapping sensation on you scalp, and may notice that your hands or fingers move slightly when the correct treatment area is located.

Once the ideal treatment area is located, the TMS therapist will mark this spot on the cap, and you will wear that cap during each subsequent treatment. During treatment, the coil will be placed gently against your head. You will hear a clicking sound and feel a gentle tapping sensation on your head. Some people may notice that each pulse causes their eye muscles to twitch, but these sensations become predictable and easy to tolerate. Each session takes approximately 20 minutes, and throughout this time you will remain awake and alert. TMS has no immediate effect on your mood or cognition, so you will immediately be able to return to your normal activities. For the greatest efficacy, at Cambridge Biotherapies we recommend a 3- to 6-week treatment course with sessions scheduled 4 to 5 days a week.

In numerous studies, TMS has been proven to be more effective than medication for the treatment of depression in patients who have not responded to one or more antidepressants. Additionally, ongoing research is demonstrating the effectiveness and safety of TMS in the treatment of obsessive-compulsive disorder, depression during and following pregnancy, post-traumatic stress disorder, and certain kinds of chronic pain.

Remission rates are variable, but a course of TMS therapy for depression can keep patients symptom-free for a year or more.

Because it uses magnetic pulses, TMS is largely free of side effects, in much the same way that magnetic resonance imaging (MRI) is free of side effects. Due to this low-risk profile, TMS is an excellent treatment choice for patients who cannot tolerate the risks or side effects of antidepressants or other biological treatments, such as ECT (electroconvulsive therapy).

Unlike some medications, TMS has no adverse effects on alertness or any aspect of cognitive functioning. In fact, there is evidence that TMS enhances certain aspects of cognitive functioning, including short-term memory.

The most common side effect of treatment is discomfort at or near the treatment site. Other reported side effects have included eye, tooth, and facial pain, muscle twitch, and skin discomfort. There is a rare risk of seizure.

Cambridge Biotherapies will work with patients and clinicians to obtain insurance reimbursement for treatment.

Many health insurance policies in Massachusetts including Blue Cross Blue Shield, Harvard Pilgrim, Tufts Health Plan, Aetna, and United Behavioral Health cover TMS.

Cambridge Biotherapies will either submit insurance claims on behalf of our patients or guide them through the submission process if they prefer to deal directly with their own insurance companies.

Unfortunately, we are not contracted with MassHealth plans, Medicare, or Medicare supplemental plans through private insurance companies. These types of insurance plans do not cover out-of-network treatment, therefore treatment at Cambridge Biotherapies would not be eligible for coverage or reimbursement. Please note that this includes BCBS of MA Medicare supplemental plans or 65+ plans.
