Addressing Concerns: Clearing Up Misconceptions About TMS Therapy Side Effects

Clearing Up Misconceptions About TMS Therapy Side Effects

Understanding and navigating mental health treatment options can feel like a daunting task. This is particularly true when considering relatively new treatment methods, such as Transcranial Magnetic Stimulation (TMS). One of the most common concerns potential patients have is understanding the possible side effects associated with TMS therapy. This article aims to clear up misconceptions about TMS therapy side effects, providing a clear, comprehensive overview of what to expect.

Introduction to TMS Therapy

Before diving into the specifics of side effects, it is crucial to understand what TMS therapy is. TMS is a non-invasive procedure that uses magnetic fields to stimulate nerve cells in the brain. It’s primarily used as a treatment for depression when other treatment methods have not been effective. It’s important to understand that like any treatment, TMS therapy can have side effects. However, they are usually minor and manageable.

Common Side Effects Of TMS Therapy

As with any medical procedure, there are some common side effects of TMS therapy that patients may experience. However, it’s important to note that these side effects are generally mild and tend to decrease over time as the body adjusts to the treatment. It is essential for patients to understand and communicate any side effects they may experience with their healthcare provider to ensure the best possible treatment experience. Let’s take a closer look at these common side effects:

Discomfort at the Treatment Site

The most common side effect of TMS therapy is discomfort or a tingling sensation at the treatment site, typically on the scalp, during or after the TMS session. The discomfort is often described as a tapping or clicking sensation as the magnetic pulses are delivered to the targeted brain areas. However, it’s important to emphasize that this discomfort is usually mild and generally well-tolerated by patients. Over the course of the treatment, as the body becomes accustomed to the procedure, the discomfort typically decreases in intensity.


Some patients may experience mild to moderate headaches after their TMS sessions, especially during the initial stages of treatment. These headaches are a known side effect of TMS therapy and are considered a normal response to the stimulation. However, it is crucial for patients to communicate any headaches they experience with their healthcare provider. In most cases, these headaches are manageable and can be alleviated with over-the-counter pain relievers. As the treatment progresses, patients may find that the frequency and intensity of headaches decrease.


It is not uncommon for some patients to experience a feeling of lightheadedness immediately after a TMS session. This side effect is typically short-lived and tends to subside shortly after the treatment. Lightheadedness can be attributed to the stimulation of specific brain areas during the session. Patients are advised to sit or lie down for a few minutes following the session to allow their bodies to adjust before resuming regular activities.

Rare Negative Side Effects of TMS Therapy

While the side effects listed above are relatively common and manageable, there are a few rare negative side effects of TMS therapy that potential patients should be aware of.


Although extremely rare, there have been cases where TMS therapy has resulted in seizures. However, the risk is very low, especially when the treatment is administered correctly by a trained healthcare provider. If you have a history of seizures, it’s important to disclose this information to your TMS provider before starting treatment.

Manic Episodes in People with Bipolar Disorder

For individuals with bipolar disorder, there’s a slight risk that TMS could trigger a manic episode. However, TMS can be safely used for treating bipolar depression with careful monitoring.

Debunking Misconceptions about TMS Therapy Side Effects

As with any medical procedure, there are a few misconceptions related to TMS therapy side effects that need to be addressed to provide a clear and accurate understanding of this innovative treatment. Let’s explore and dispel these misconceptions:

TMS Therapy is Painful and Uncomfortable

TMS therapy is non-invasive and generally well-tolerated by patients. During the session, individuals may feel a tapping or clicking sensation on their scalp as the magnetic pulses are delivered to the targeted brain regions. While this sensation may take some getting used to, most patients find it manageable and painless. The discomfort experienced is minimal and typically subsides quickly, with many patients describing it as no more than a slight inconvenience.

TMS Therapy Causes Memory Loss

Another misconception arises from comparisons made with electroconvulsive therapy (ECT), a different treatment used for severe depression and other mental health conditions. ECT can have memory loss as a side effect, which has led some to erroneously assume that TMS therapy might have a similar impact. However, it is important to clarify that TMS therapy and ECT are fundamentally different procedures.

TMS therapy specifically targets specific brain regions associated with mood regulation, whereas ECT involves inducing controlled seizures under anesthesia. Numerous studies have shown that TMS therapy does not lead to any negative effects on memory or cognitive function. Patients undergoing TMS therapy can expect their memory and cognitive abilities to remain unaffected throughout the treatment course.

TMS Therapy Has Long-Term Side Effects

Some individuals may worry about potential long-term side effects associated with TMS therapy. While it is natural to be cautious, research and clinical experience show that TMS therapy is generally safe and well-tolerated. As mentioned earlier, the most common side effects of TMS therapy are typically mild and transient, with no evidence suggesting harmful long-term effects.

Patients can be reassured that TMS therapy has undergone extensive research and testing to ensure its safety and efficacy. Many individuals have experienced significant improvement in their mental health conditions without any long-term adverse effects from TMS therapy.


While it’s normal to have concerns about the potential side effects of any treatment, it’s essential to have a balanced understanding of what these side effects may entail. The side effects of TMS therapy are typically mild and tend to subside over time. Any serious side effects are rare and are closely monitored by healthcare providers during treatment.

If you are considering TMS therapy and are concerned about potential side effects, it is recommended that you have an open discussion with your healthcare provider. They can provide detailed information based on your personal medical history and can monitor your response to the treatment to ensure it is both safe and effective for you.

In conclusion, while TMS therapy may have side effects like any other treatment, they are generally mild and manageable. The potential benefits of this innovative therapy, particularly for those who have not found success with other treatment options, can offer hope and a path toward improved mental health.
