What is TMS and how does it optimzie mental wellness in 2025

She came to me after three years of trying.

Three years of antidepressants — some that blunted her emotions until she felt like she was living behind glass, others that simply never worked at all. Three years of adjusting dosages, switching medications, managing side effects that traded one kind of suffering for another. She was not looking for a miracle. She was looking for something that would finally let her feel like herself again.

When I introduced her to transcranial magnetic stimulation, she was cautiously hopeful. By her sixth week of treatment, she described something she had almost forgotten was possible — waking up in the morning and feeling ready for the day.

That story is not unusual in my practice. It is, in fact, becoming one of the most common and rewarding arcs I witness. And it begins with a technology that more patients deserve to understand.

The Brain as a System That Can Be Recalibrated

To understand TMS, it helps to first understand what depression, anxiety, and cognitive fatigue actually look like inside the brain.

Modern neuroimaging has made it increasingly clear that mood disorders are not simply chemical imbalances in the way we once described them. They are also — and perhaps more precisely — disruptions in the connectivity and activity patterns of specific brain networks. Certain regions become underactive. Others become overactive. Communication between areas that should work in concert becomes dysregulated.

The result is a brain that is not functioning the way it was designed to. And when we recognize that, a new question emerges: rather than only trying to alter brain chemistry through medication, what if we could directly influence the activity of those brain networks themselves?

That is exactly what TMS does.

What TMS Actually Is

Transcranial magnetic stimulation is a non-invasive neuromodulation therapy that uses precisely targeted magnetic pulses to stimulate specific regions of the brain. The technology is FDA-cleared and has been used clinically for decades, with the body of supporting research growing substantially in recent years.

During a TMS session, a small magnetic coil is positioned gently against the scalp. It delivers focused electromagnetic pulses that pass painlessly through the skull and into the underlying brain tissue. These pulses activate neurons in targeted regions, gradually reestablishing healthier patterns of activity and connectivity over the course of treatment.

There is no anesthesia. No sedation. No recovery time. Most patients sit comfortably during a session and return to their normal day immediately afterward. The experience is often described as a light, rhythmic tapping sensation near the treatment site.

The Neuroscience Behind the Results

The primary target for TMS in the treatment of depression and anxiety is the dorsolateral prefrontal cortex — a region of the brain closely involved in mood regulation, executive function, emotional processing, and the modulation of the limbic system, which governs our stress and fear responses.

In individuals with depression, this region is typically underactive. Repeated TMS sessions essentially train the neurons in this area to fire more consistently and robustly. Over time, this stimulation reshapes the functional connectivity of the broader mood-regulating network — producing changes that are not temporary, but neurologically meaningful.

Think of it as physical therapy for the brain. Just as targeted exercise restores strength and coordination to an injured muscle, TMS restores healthier patterns of activation to circuits that have become dysregulated. The brain is extraordinarily plastic. Given the right stimulus, it responds.

What TMS Can Address

In my practice, TMS has become a valuable tool across a wider landscape of mental wellness than many patients initially expect.

Treatment-Resistant Depression. This is the most well-established application and the one with the longest clinical track record. For patients who have not responded adequately to one or more antidepressant medications, TMS offers a meaningful alternative. Studies consistently show response rates that significantly outperform additional medication trials in this population. For many of my patients, it represents the turning point they had stopped believing was possible.

Anxiety Disorders. Generalized anxiety, social anxiety, and the anxiety that so often accompanies depression are increasingly recognized as responsive to TMS. Protocols targeting specific brain regions involved in threat processing and emotional regulation can reduce the persistent, exhausting vigilance that defines anxiety — without the sedation or dependence concerns associated with many anti-anxiety medications.

Cognitive Fatigue and Brain Fog. One of the most compelling emerging applications in 2025 is the use of TMS to address cognitive symptoms — the inability to concentrate, slowed thinking, mental exhaustion — that accompany depression, burnout, long COVID, and other conditions affecting brain function. Patients frequently report improvements in clarity, processing speed, and mental stamina alongside improvements in mood.

Obsessive-Compulsive Disorder. Deep TMS, a more advanced form of the technology, has received FDA clearance for OCD. For patients who have found limited relief through conventional approaches, this represents a genuinely new path forward.

Adjunctive Mental Wellness Optimization. Not every patient seeking TMS is in crisis. Some of the most interesting cases I work with involve high-functioning individuals — executives, creatives, caregivers — who want to optimize their cognitive and emotional resilience, not simply treat a diagnosis. TMS, particularly when integrated with a comprehensive precision medicine approach, can serve as a meaningful tool for this kind of intentional brain health.

What a Course of Treatment Looks Like

A standard TMS protocol typically involves daily sessions five days per week over approximately six weeks, though treatment parameters are always individualized based on the patient's clinical presentation, history, and goals.

Each session lasts between twenty and forty minutes depending on the protocol being used. Patients come in, settle into a comfortable chair, and the treatment is administered while they are fully awake and aware. Many read, listen to music, or simply rest. Afterward, they leave and continue their day without restriction.

Some patients notice subtle shifts within the first two to three weeks. For others, the most meaningful changes emerge in the final weeks of the course or even in the weeks following its completion, as the brain continues to consolidate the neural changes initiated by treatment. There is rarely a dramatic single moment of transformation. More often, patients describe a gradual lifting — a slow return of color to a world that had gone gray.

How TMS Fits Within a Precision Medicine Framework

I want to be clear about something: TMS is not a standalone solution in isolation, and I do not practice it that way.

At Modern Human MD, TMS is integrated into a broader, individualized approach to mental wellness that includes thorough laboratory evaluation, hormonal assessment, nutritional optimization, and when appropriate, genomic insight. Mental health does not exist independently of the body. Thyroid dysfunction, sex hormone imbalances, nutritional deficiencies, inflammatory burden, and sleep disruption all influence brain function in ways that medication and neuromodulation alone cannot fully address.

Before a patient begins TMS in my practice, we take the time to understand the full picture of their biology. During and after treatment, we continue to refine the surrounding protocol. The result is a level of care that supports not just symptom relief, but genuine and lasting neurological health.

The Question I Hear Most Often

Is TMS right for me?

It is a reasonable question, and the honest answer is that it depends on the full context of your history, your biology, and your goals. TMS is not a universal solution, and I would be doing a disservice to suggest otherwise. But for a thoughtfully selected patient — particularly one who has struggled with depression or anxiety that has not fully responded to prior treatments, or one who is looking for a non-pharmacological path forward — it can be genuinely life-changing.

The woman I described at the beginning of this piece is doing well. She no longer takes antidepressants. She completed her TMS course and then worked with me to address the hormonal and nutritional factors that had been quietly compounding her vulnerability all along. She runs along the ocean in the mornings now. She told me recently that she had forgotten what it felt like to look forward to things.

That is what good medicine can do.

Mental Wellness in 2025

We are living through a meaningful evolution in how we understand and care for the brain. The tools available today — when used thoughtfully, precisely, and within the context of the whole person — offer possibilities that simply did not exist a decade ago.

TMS is one of those tools. Not a trend. Not a shortcut. A scientifically grounded, clinically validated approach to helping the brain do what it was designed to do.

If you have been living with depression, anxiety, or cognitive symptoms that have resisted conventional approaches, or if you are simply curious about what optimized brain health could look like for you, I would welcome the conversation. Understanding your options is the first step. Taking action on that understanding is where the real change begins.
