What is rTMS, and how does it work?
Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain stimulation technique. It uses a magnetic coil placed against the scalp to deliver magnetic pulses, which stimulate specific areas of the brain associated with mood regulation and pain perception.
Here is how it works in simple terms:
A device with a magnetic coil is placed on your head.
It sends gentle magnetic pulses to areas of the brain involved in mood regulation.
These pulses help “wake up” or reset parts of the brain that might not be working as they should.
What conditions is rTMS commonly used to treat?
rTMS is primarily used to treat major depressive disorder (MDD) in individuals who have not responded to medications or therapy. It is also being used for other conditions, including anxiety, post-traumatic stress disorder (PTSD) tinnitus and chronic pain.
Is rTMS a safe treatment option?Yes, rTMS is FDA and Health Canada approved for certain conditions and is considered safe when administered by trained professionals.
How is rTMS different from other treatments like medications or therapy?
Unlike medications, rTMS directly targets brain activity without systemic side effects that can occur with antidepressants. It also differs from electroconvulsive therapy (ECT) in that it does not require sedation and typically has fewer cognitive side effects.
Why do you need multiple rTMS treatments?You need consecutive rTMS sessions over a few weeks because the treatment works by gradually retraining your brain over time. Think of it like going to the gym: one workout will not make you stronger, but consistent sessions over time help build and maintain strength.
Here is why:
Who is a suitable candidate for rTMS?
Candidates for rTMS are typically adults with treatment-resistant depression, meaning they have not responded to at least one or two antidepressant trials or psychotherapy.Other conditions it may benefit include:Anxiety disorders, such as Generalized Anxiety Disorder (GAD) -C, Post-Traumatic Stress Disorder (PTSD), chronic pain conditions, like fibromyalgia, neurological disorders, such as migraines or certain symptoms of Parkinson’s disease. However, its strongest evidence and most common use remain with treatment-resistant depression.
Are there conditions or circumstances where rTMS is not recommended?
rTMS is not recommended for individuals with metal implants in or near the head (except dental fillings), active seizures, or certain neurological conditions. Your practitioner will assess your medical history to determine suitability.
Can I have rTMS if I am pregnant or breastfeeding?
Due to the limited amount of research and evidence of rTMS for pregnant or breastfeeding women, we do not offer this at this time.
Does rTMS interact with medications or other treatments?
rTMS can often be used alongside medications or therapy.
What are the potential side effects of rTMS?
Common side effects include mild scalp discomfort, headache, or tingling at the treatment site. Serious side effects, like seizures or mania, are extremely rare.
Are there any long-term risks associated with rTMS?
Current research suggests no significant long-term risks. rTMS is well-tolerated in most individuals, even with repeated courses.
What should I do if I experience side effects?
Report any side effects to your practitioner. Adjustments to the treatment intensity or schedule can often reduce discomfort.
Is rTMS supported by clinical research?
Yes, rTMS is backed by numerous studies and is FDA and Health Canada approved for certain conditions. Research continues to explore its potential for other disorders.
Are there new advancements or experimental uses of rTMS?
Emerging research includes using rTMS for conditions like autism, Alzheimer’s disease, and stroke rehabilitation.
What happens during an rTMS session?
During a session, you will be provided with a special cap that will be used for each treatment. You will sit in a comfortable chair while a magnetic coil is placed against your scalp. The device delivers a series of magnetic pulses to stimulate targeted brain areas. Once your treatment has finished you can continue your usual activities.
Does rTMS hurt?
Most people describe the sensation as tapping or tingling on the scalp, which can feel unusual but is not typically painful. Mild discomfort or headache may occur initially but often decreases with time.
How long does each session last?
The first appointment will be booked for about an hour as there are some initial steps that need to be completed. Following that your appointments will be booked for 30 minutes, for most people the actual treatment only lasts 12 minutes per session. The protocols may vary depending on your needs, meaning time can vary.
How many sessions will I need?
Most treatment courses involve daily sessions (Monday–Friday) for 2 to 6 weeks, totaling 10–30 sessions.
What does the equipment look like?
The equipment includes a chair like a dentist’s chair and a magnetic coil connected to a machine that delivers the pulses.
Do I need to prepare for rTMS sessions in any way?
No special preparation is required. You should arrive well-rested and avoid alcohol or drugs before sessions. Wear comfortable clothing and avoid wearing metallic accessories.
How effective is rTMS for treating depression or other conditions?
Studies show that rTMS can significantly improve symptoms in about 50–70% of individuals with treatment-resistant depression, with ever higher results for non-treatment-resistant cases, with many achieving complete remission.
When can I expect to notice results from rTMS?Most people begin to start to notice improvements around 15 to 20 sessions (3-4 weeks).
Can rTMS cure my condition, or will I need ongoing treatment?
While rTMS may lead to remission of symptoms, it is not considered a cure. Maintenance sessions or additional therapies may be recommended for long-term management.
What happens if rTMS does not work for me?
If rTMS is not effective, other options may include adjusting the treatment protocol, trying different therapies, or in combination with Ketamine-Assisted Therapy.
How much does rTMS cost, and is it covered by insurance?
Costs vary by protocol, and you can view them here (https://atmacena.com/repetitive-transcranial-magnetic-stimulation-rtms/). Some insurance plans cover rTMS for treatment-resistant depression, please check with your insurance provider.
Can I drive or return to work immediately after a session?
Yes, most people can resume normal activities, including driving, immediately after a session.
What should I do if I miss a session?
Missed sessions should be rescheduled as soon as possible to ensure the continuity and effectiveness of treatment. Missing an occasional appointment will not impact your results, however, longer breaks in the treatment are discouraged and may impact effectiveness.
Will I need follow-up care or maintenance sessions?
Some individuals benefit from periodic maintenance sessions to sustain improvement, particularly if symptoms recur.
How can I maximize the benefits of rTMS after treatment ends?
Maintain a healthy lifestyle, continue therapy and/or medications as prescribed, and address any triggers or stressors.
Can I combine rTMS with other therapies like psychotherapy or medications?
Yes, pairing repetitive Transcranial Magnetic Stimulation with Ketamine-Assisted Therapy (KAT) offers a synergistic approach to mental health treatment, combining the strengths of both modalities for enhanced outcomes. Combining rTMS with therapy or medications often enhances overall treatment outcomes.
