How Long Has TMS Therapy Been Around?
Transcranial magnetic stimulation, commonly known as TMS therapy, has been around since the mid-1980s. Researchers first experimented with the technique in 1985, exploring its ability to stimulate nerve cells in the brain using magnetic fields. While it began as a tool for neuroscience research, over the decades, TMS has evolved into a clinically recognized treatment for various mental health conditions, most notably depression, obsessive-compulsive disorder (OCD), and smoking addiction. Its journey from laboratory curiosity to FDA-approved therapy spans nearly four decades of innovation and clinical study.

A Brief History of TMS
The story of TMS starts with the desire to understand the brain more safely and non-invasively. In the early 1980s, neuroscientists were looking for ways to stimulate the brain without the risks associated with electrical brain stimulation, which could be painful and invasive.
In 1985, Dr. Anthony Barker and his colleagues at the University of Sheffield in England developed the first transcranial magnetic stimulation device. This innovation allowed researchers to send brief magnetic pulses to specific areas of the brain, causing localized electrical currents that could activate nerve cells.
Throughout the 1990s, TMS was primarily used as a research tool to study brain function, cortical mapping, and neural connectivity. Researchers began to notice that repetitive stimulation could influence brain circuits associated with mood, leading to the first clinical experiments in the late 1990s and early 2000s aimed at treating depression.
Repetitive Transcranial Magnetic Stimulation (rTMS): The Clinical Breakthrough
Repetitive transcranial magnetic stimulation (rTMS) involves delivering repeated pulses to targeted areas of the brain over multiple sessions. This method became the foundation for TMS as a therapeutic intervention. Early trials of rTMS for depression showed promising results, particularly for patients who had not responded to traditional antidepressants. By stimulating the left dorsolateral prefrontal cortex, an area implicated in mood regulation, rTMS appeared to increase neural activity and improve depressive symptoms over time.
Magnetic Stimulation and Its Role in Mental Health
The term “magnetic stimulation” refers to the technique of using magnetic fields to create electrical currents in the brain. While the technology may sound high-tech, the concept is straightforward: a magnetic coil placed near the scalp produces a focused field that temporarily alters neuronal activity. Over multiple sessions, this modulation can help recalibrate circuits associated with mood disorders.
The application of magnetic stimulation has expanded beyond the treatment of depression, OCD, and smoking cessation. Researchers are investigating its potential in treating conditions such as anxiety, PTSD, autism, ADHD, bipolar disorder, and even cognitive decline. While the strongest evidence remains in mental health and mood disorders, the scope of TMS therapy continues to grow.
TMS Treatment Today: What It Involves
Modern TMS treatment involves daily sessions, five days a week, over a period of four to six weeks. Each session lasts around 30–40 minutes and is conducted while the patient is awake and seated comfortably.
There are also accelerated treatment protocols, involving 10 daily sessions (each lasting 3-9 minutes) over 5 days.
Unlike electroconvulsive therapy (ECT), TMS does not require anesthesia and carries minimal systemic side effects. Some patients may experience mild scalp discomfort or a tapping sensation at the site of stimulation, but serious side effects are rare.
The rise of TMS treatment has also been aided by technological advancements, including neuronavigation systems that enable clinicians to target precise brain regions with greater accuracy. These advancements have enhanced the effectiveness of TMS and reduced the number of sessions needed for meaningful results.
FDA Approval: A Milestone in Depression Treatment
TMS gained a significant milestone in 2008 when the U.S. Food and Drug Administration (FDA) approved it for treating major depressive disorder in adults who had not responded to antidepressant medications. This approval was based on rigorous clinical trials demonstrating the therapy’s safety and efficacy. Since then, additional TMS protocols and devices have received FDA clearance, including Deep TMS and Theta Burst Stimulation, which offer different patterns of magnetic stimulation for improved outcomes.
FDA approval not only legitimized TMS as a mainstream treatment but also paved the way for insurance coverage in many cases, making it more accessible to patients struggling with treatment-resistant depression.
Deep TMS: Next-Generation Brain Stimulation
Deep TMS is an advanced form of the therapy designed to reach deeper regions of the brain than traditional TMS. Using specialized coils, Deep TMS can influence broader neural networks implicated in depression and other psychiatric conditions. Clinical studies suggest that Deep TMS may offer higher response rates for some patients, particularly those with more severe or persistent symptoms.
The development of Deep TMS illustrates how TMS therapy continues to evolve. Researchers are now exploring its applications in post-traumatic stress disorder, bipolar disorder, autism, and chronic pain, highlighting its potential beyond standard depression treatment.
TMS Therapy and Depression Treatment: Who Can Benefit?
TMS therapy has become a key option in depression treatment, particularly for individuals who have not responded to medications or psychotherapy. Unlike drugs that can take weeks to show improvement, some patients report noticeable changes in mood after just a few sessions of TMS.
The therapy is typically recommended for adults and adolescents with major depressive disorder. However, studies are ongoing to determine its safety and effectiveness in younger populations, as well as in combination with other mental health interventions. Clinicians often assess each patient’s medical history, previous treatments, and specific symptom profile before recommending TMS therapy.
The Science Behind the Success
TMS therapy targets brain regions involved in mood regulation and neural plasticity. Repeated sessions help strengthen neural connections and can normalize activity in underactive areas of the brain. Neuroimaging studies have shown changes in brain function after TMS treatment, providing evidence of its physiological effects.
Moreover, TMS is generally well-tolerated, with side effects limited to mild headaches or discomfort at the site of stimulation. This safety profile, combined with proven effectiveness, has contributed to its growing popularity among clinicians and patients alike.
Looking Ahead: The Future of TMS
Since its inception in 1985, TMS has transitioned from an experimental tool to a widely recognized treatment for mental health disorders. The therapy continues to evolve, with innovations like Deep TMS, Theta Burst Stimulation, and personalized targeting strategies. Researchers are also investigating its potential in treating conditions beyond depression and OCD, including anxiety, bipolar disorder, PTSD, and cognitive impairments, such as Alzheimer’s disease.
As TMS technology improves and awareness grows, more patients will likely have access to this non-invasive, effective treatment option. With nearly 40 years of development behind it, TMS has firmly established itself as a cornerstone of modern mental health therapy.
