Transcranial magnetic stimulation (TMS) is a noninvasive treatment that uses magnetic pulses to stimulate nerve cells in specific parts of the brain. For some people with depression, it can reduce symptoms when other treatments have not worked well. Anxiety is a more complicated story. Some patients do report feeling more anxious during or shortly after treatment, but the evidence does not show that TMS reliably makes anxiety worse in most people.
The honest position is this: anxiety can rise during a course of TMS, but it is usually temporary, often tied to the treatment session itself, and not a sign that the therapy is failing. Whether TMS helps or worsens anxiety depends heavily on why the person is being treated and which brain areas are targeted.
What Is TMS and How Does It Work?
TMS delivers focused magnetic pulses through a coil placed against the scalp. These pulses pass through the skull and change the activity of nerve cells in a small area of the brain just beneath the coil. The most common form, repetitive TMS (rTMS), is typically aimed at the dorsolateral prefrontal cortex, a region involved in mood regulation.
The treatment is not a shock. It does not require anesthesia. Most people feel a tapping sensation on the scalp and hear a clicking sound. A session usually lasts under an hour, and many patients drive themselves home afterward.
TMS is cleared by the U.S. Food and Drug Administration for major depressive disorder in adults who have not responded well to medication, and for some other conditions. It is not a first-line treatment. It is generally considered when other approaches have not worked.
The key point for anxiety: TMS changes brain activity in targeted regions. The brain circuits involved in depression and anxiety overlap but are not identical. That overlap helps explain why the same treatment can affect both conditions, sometimes in opposite directions.
Does TMS Actually Make Anxiety Worse?
For most people, no. Large studies of TMS for depression generally report that anxiety symptoms improve alongside depressive symptoms in many patients. Anxiety and depression commonly occur together, and treating one often eases the other.
That said, a subset of patients do report increased anxiety during treatment. This is a real observation in clinical settings, not a myth. The reasons are not fully settled. Several explanations are plausible:
- Anxiety can be a transient side effect of the stimulation itself, especially early in a course of treatment.
- Starting a new treatment can raise worry in anyone, particularly people already prone to anxiety.
- Changes in brain activity during treatment may briefly unsettle mood regulation before it stabilizes.
- Some people with anxiety disorders may be more sensitive to the physical sensations of the procedure.
What the evidence does not support is the idea that TMS is a common cause of lasting or severe anxiety worsening. Serious psychiatric worsening during TMS is uncommon, though it is a known risk that clinicians monitor for.
Why Might Anxiety Increase During TMS?
The stimulation target matters. Different brain regions are linked to different symptoms. When TMS is aimed at areas involved in mood, it can influence anxiety circuits too. In some patients, the net effect on anxiety is positive. In others, it may be neutral or briefly negative.
There is also a practical dimension. TMS requires repeated visits, often daily for several weeks. That schedule can be disruptive. Worry about missing work, the cost, or whether the treatment will help can all feed anxiety. This is not the treatment acting on the brain directly, but it is part of the experience.
Some research suggests that people with certain anxiety profiles may respond differently to TMS than people with depression alone. The evidence here is still developing. Researchers are actively studying which patients benefit most and which brain targets work best for anxiety specifically.
Is TMS Used to Treat Anxiety Itself?
This is where the picture gets more interesting. TMS is being studied as a treatment for anxiety disorders, not just depression. Early research has looked at its use in generalized anxiety disorder, panic disorder, obsessive-compulsive disorder, and post-traumatic stress disorder.
The evidence for anxiety treatment is less established than for depression. Some studies show promising results. Others are less clear. TMS is not currently a standard, first-choice treatment for most anxiety disorders, and it is not FDA-cleared for anxiety as a standalone condition.
Some clinicians do use TMS off-label for anxiety, particularly when it occurs alongside depression. This is a matter of clinical judgment, not a firmly established standard of care. If you are considering TMS primarily for anxiety, it is worth asking your provider directly about the evidence for your specific condition.
What Are the Known Side Effects of TMS?
The most common side effects are mild and temporary. Headache and scalp discomfort during or after sessions are frequently reported. Some people notice tingling or twitching in facial muscles during treatment.
More serious risks are rare but real. Seizure is the most significant known risk, which is why screening matters. People with certain medical conditions, implanted metal devices, or a history of seizures may not be candidates. Clinicians screen for these before starting.
Mood changes, including anxiety, are recognized as a possible side effect. This is why good clinical monitoring matters. If anxiety increases during a course of TMS, that is information your provider needs, not something to push through silently.
What Should You Do If Anxiety Gets Worse During Treatment?
Tell your provider. This is the single most useful step. Anxiety that rises during TMS may be manageable with adjustments to the treatment plan, added support, or a change in approach. Your care team can help you decide whether to continue, pause, or modify treatment.
Do not stop treatment abruptly on your own without discussing it, especially if you are being treated for depression. Stopping suddenly can have its own risks. A conversation with your clinician is the right move.
It also helps to track your symptoms. Notice when anxiety rises, how long it lasts, and whether it is tied to sessions or to other life events. That pattern can guide your provider’s decisions.
If anxiety becomes severe, or if you have thoughts of harming yourself, seek help right away. Do not wait for your next appointment. Contact a crisis line, go to an emergency room, or reach out to a trusted person who can help you get support.
What Does the Overall Evidence Say?
The evidence does not support the claim that TMS commonly makes anxiety worse. For many patients, anxiety improves along with depression. But increased anxiety is a recognized possibility for some people, and it deserves attention rather than dismissal.
This is a treatment with real effects on brain activity. Those effects are not always predictable for every symptom. The best approach is honest monitoring, open communication with your care team, and realistic expectations.
If you are considering TMS, ask your provider about how it might affect your anxiety specifically, not just your depression. Ask what signs to watch for and what to do if anxiety rises. A good clinician will welcome those questions.
Frequently Asked Questions
Can TMS make anxiety worse?
It can in some people, but this is not the typical response. Most patients see anxiety improve alongside depression, though increased anxiety during treatment is a recognized possibility that clinicians monitor.
How common is increased anxiety during TMS?
It is reported in a minority of patients, but exact rates vary across studies and are not firmly established. Your provider can tell you what to watch for based on your specific situation.
Is TMS safe for people with anxiety disorders?
TMS is generally well tolerated, but it is not FDA-cleared as a standalone treatment for most anxiety disorders. Some clinicians use it off-label, so discuss the evidence for your condition with your provider.
Should I stop TMS if my anxiety gets worse?
Talk to your provider before making any changes. Anxiety that rises during treatment can often be managed with adjustments, and stopping suddenly without guidance may carry its own risks.
