Through a magnetic coil, the NeuroStar TMS Therapy system generates highly concentrated, magnetic fields which turn on and off very rapidly. These magnetic fields are the same type and strength as those produced by a magnetic resonance imaging (MRI) machine.
The treatment coil is applied to the head above the left prefrontal cortex. This part of the brain is involved with mood regulation, and therefore is the location where the magnetic fields are focused. These magnetic fields do not directly affect the whole brain; they only reach about 2-3 centimeters into the brain directly beneath the treatment coil. As these magnetic fields move into the brain, they produce very small electrical currents. These electrical currents activate cells within the brain which are thought to release neurotransmitters like serotonin, norepinephrine, and dopamine. Since depression is thought to be the result of an imbalance of these chemicals in the brain, TMS can restore that balance and, thus, relieve depression.
A NeuroStar® TMS Therapy treatment session is a short outpatient procedure that lasts about 19-37 minutes, depending on what the doctor determines is the correct protocol. During treatment, you can relax in the treatment chair. You can also speak with our TMS Specialists whenever necessary. After the procedure, you can immediately return to your normal routine, including driving.
Because your TMS-certified physician needs to determine how to most effectively administer treatment, your first session could last up to an hour and a half. You will be provided and asked to wear protective earplugs, as the system emits a tapping sound during operation.
Your TMS physician will first perform a test to identify your motor threshold. The motor threshold is the amount of magnetic field strength that results in a movement of your right thumb. This test is important because it identifies the magnetic field strength that will be used in your treatment. This field strength is customized for each patient to deliver the correct treatment dose.
After this initial procedure, the TMS physician will determine the place on the head where the TMS treatment will be applied and the magnetic coil will be moved to that location. This will allow you to receive optimal treatment.
The TMS Specialist will then administer TMS Therapy over an approximately 19-37 minute period. In 10-second intervals, the device will deliver rapid “pulses” of the magnetic fields. These will feel like tapping on your scalp. Some patients may find this tapping uncomfortable. Your physician may be able to make adjustments to reduce this discomfort.
Immediately following each treatment session, you may return to your normal daily routine, including driving. During or after treatment you may experience a headache or discomfort at the site of stimulation. These are common side effects that often improve as further treatment sessions are administered. If necessary, you can treat this discomfort with an over-the-counter analgesic. If these side effects persist, your TMS physician can temporarily reduce the strength of the magnetic field pulses being administered in order to make treatment more comfortable.
In clinical trials, most patients who benefited from NeuroStar TMS Therapy experienced results by the fourth week of treatment. Some patients may experience results in less time, while others may take longer. You should discuss your depression symptoms with your physician throughout the treatment course. If symptoms persist, you may want to consider other antidepressant options.
Since the FDA clearance of TMS in 2008, insurance coverage for eligible patients has increased significantly. Currently, there are over 60 coverage polices for TMS, including most Medicare contractors. Although TMS is not a first line of treatment, it is an alternative option for those who are not responding to or cannot tolerate medications. Patients are encouraged to speak directly with their Doctor regarding any specific insurance questions. Patients can also contact a Reimbursement Specialist and receive assistance with understanding insurance coverage and verifying insurance benefits.

TMS stands for Transcranial Magnetic Stimulation. It is used to treat depression by stimulating the brain non-invasively using electromagnetic fields, similar to those produced by an MRI machine. During TMS Therapy, a magnetic field is administered in very short pulses to the part of the brain that research has demonstrated to be associated with depression. The typical initial course of treatment is about 19-37 minutes daily over 4-6 weeks.
The NeuroStar TMS Therapy system uses short pulses of magnetic fields to stimulate the area of the brain that is thought to function abnormally in patients with depression. The magnetic field produces an electric current in the brain that stimulates the brain cells (neurons). This results in changes that are thought to be beneficial in the treatment of depression.
It usually takes time for healthcare insurers to establish coverage policies for newly approved treatments such as NeuroStar TMS. However, many commercial and Medicare plans have recognized the effectiveness of treating depression with TMS Therapy and now cover TMS as part of their plans. See here for a full list of insurance plans that cover TMS.
NeuroStar® is non-systemic (does not circulate in the blood throughout the body), so it does not have side effects such as weight gain, sexual dysfunction, nausea, dry mouth, sedation, etc. The most common side effects reported during clinical trials were headache and scalp discomfort – generally mild to moderate – occurring less frequently after the first week of treatment.
No. TMS Therapy involves a unique method of using pulsed magnetic fields for therapeutic benefit. The intensity of the magnetic field is similar to that of the magnetic fields used in magnetic resonance imaging, or MRI. These techniques differ radically from the popular use of low intensity, static magnetic fields. These products deliver weak and undirected static fields that are not capable of activating brain cells.
No, the two procedures are very different. While both are effective in the treatment of depression, there are many differences in safety and tolerability.
During TMS Therapy, patients sit in a chair and are awake and alert throughout the entire 19-37 minute procedure – no sedation is used with TMS Therapy. Patients can transport themselves to and from treatment.
In over 10,000 active treatments with the NeuroStar TMS Therapy system in clinical trials, no seizures were observed. TMS Therapy was also shown to have no negative effects on memory function in these studies.
In contrast, “shock therapy,” or electroconvulsive therapy (ECT), 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 or a even few hours after a treatment.
Short-term confusion and memory loss are common with ECT, and long-term disruptions in memory have been shown to occur and may persist indefinitely in some people. Because of the side effects associated with ECT, a significant amount of caregiver support is required.
A typical course of TMS Therapy is 5 times per week for 19-37 minutes sessions, depending on what the doctor determines is the correct protocol, over 4-6 weeks.
Any additional treatments are based on clinical judgment.
NeuroStar TMS Therapy has been shown to be well tolerated and the Neurostar TMS Therapy system has been demonstrated to be safe in clinical trials. Throughout over 10,000 active treatments performed in clinical trials, the most commonly reported side effect related to treatment was scalp discomfort during treatment sessions. This side effect was generally mild to moderate, and occurred less frequently after the first week of treatment. Less than 5% of patients treated with NeuroStar TMS Therapy discontinued treatment due to side effects.
In NeuroStar clinical trials, over 10,000 TMS treatments demonstrated its safety, with no occurrence of seizures. However, there is a small risk of a seizure occurring during treatment. This risk is no greater than what has been observed with oral antidepressant medications.
While NeuroStar TMS Therapy has been demonstrated to be effective, not all patients will benefit from it. Patients should be carefully monitored for worsening symptoms, signs or symptoms of suicidal behavior, and/or unusual behavior. Families and caregivers should also be aware of the need to observe patients and notify their treatment provider if symptoms worsen.
No, NeuroStar TMS Therapy uses the same type and strength of magnetic fields as MRIs (magnetic resonance imaging), which have been used in tens of millions of patients around the world and have not been shown to cause tumors. The magnetic energy used in a full course of TMS Therapy is a small fraction of just one brain scan with an MRI.
No, the NeuroStar TMS Therapy system was systematically evaluated for its effects on memory. Clinical trials demonstrated that NeuroStar TMS Therapy does not result in any negative effects on memory or concentration.
No, the most common side effect related to treatment was scalp discomfort during treatment sessions. This side effect was generally mild to moderate, and occurred less frequently after the first week of treatment.
If necessary, you can treat this discomfort with an over-the-counter analgesic. If these side effects persist, your doctor can temporarily reduce the strength of the magnetic field pulses being administered in order to make treatment more comfortable.
Less than 5% of patients treated with NeuroStar TMS Therapy discontinued treatment due to side effects.
NeuroStar TMS is the only TMS system with the durability of its effects established over 12 months. In a clinical trial, 2 out of 3 patients who had either responded to treatment or completely remitted their depression symptoms reported 12 months later that they remained at the level they were at the end of the trial. Additionally, after the trial, only 1 in 3 patients needed to return for ‘maintenance’ TMS sessions.
Yes. In clinical trials, NeuroStar TMS Therapy was safely administered with and without other antidepressant medications.
No, the NeuroStar TMS Therapy system is the first TMS device to be cleared by the U.S. Food and Drug Administration (FDA) for the treatment of major depression.
The NeuroStar TMS Therapy system is also the first TMS device to have been evaluated in a large, multicenter, controlled clinical trial, as well as the only TMS system with the durability of its effects over 12 months established.
