Week by Week: What to Expect During TMS Therapy for Treatment-Resistant Depression at Synergy of Monticello

When you have been living with treatment-resistant depression – trying medication after medication without adequate relief – the idea of starting something new can feel both hopeful and uncertain. One of the most common questions patients ask when they first contact Synergy of Monticello is how TMS therapy works and what the treatment experience actually looks like from start to finish. That is a completely reasonable question, and having a clear picture of the journey ahead can make the process feel much more approachable.

Transcranial Magnetic Stimulation (TMS) is a non-invasive, FDA-cleared treatment designed specifically for adults with treatment-resistant depression (TRD) – meaning depression that has not responded adequately to at least one course of antidepressant medication. Unlike systemic treatments that travel through the bloodstream, TMS uses focused magnetic pulses to stimulate targeted areas of the brain associated with mood regulation. It does not require anesthesia, sedation, or any recovery time, and most patients return to their daily activities immediately after each session.

Below, we walk through the full patient journey at Synergy of Monticello – week by week – so you know exactly what to expect if you choose to explore TMS for treatment-resistant depression.

How TMS Therapy Works: The Science Behind the Treatment

Before diving into the weekly timeline, it helps to understand how TMS therapy works at a fundamental level. During each session, an electromagnetic coil is placed against the scalp near the forehead. This coil generates brief, targeted magnetic pulses – similar in strength to those used in an MRI – that pass through the skull and stimulate nerve cells in the prefrontal cortex, a region of the brain closely linked to mood regulation.

In individuals with depression, activity in this area of the brain is often underactive. TMS works by encouraging these neurons to fire more effectively, which may help restore healthier communication patterns within neural circuits over time. The treatment is non-systemic, meaning it does not introduce any drugs into your body. There are no systemic side effects like weight gain, fatigue, or sexual dysfunction that are commonly associated with antidepressant medications.

A standard course of TMS typically consists of sessions administered five days per week over approximately six weeks, though treatment length may vary depending on individual response and clinical recommendations. Each session generally lasts between 19 and 40 minutes, depending on the specific protocol used by your treatment team at Synergy of Monticello.

Before Week 1: Your Initial Consultation and Brain Mapping

Evaluation and Treatment Planning

Your journey begins with a comprehensive evaluation at Synergy of Monticello, located in Monticello, New York. During this consultation, a qualified provider will review your mental health history, current symptoms, and previous treatment experiences – including which medications you have tried and how you responded to them. This evaluation is essential for confirming that TMS is an appropriate option for your specific situation.

If TMS is recommended, your provider will discuss the treatment plan in detail, answer any questions you may have, and help you understand what to expect over the coming weeks. This is also a good time to ask about insurance coverage. TMS therapy at Synergy of Monticello is covered by several major insurance providers, including UnitedHealthcare, Medicare, Aetna, Value Options, Optum, GHI, MVP Health Care, Empire BCBS, and Emblem Health.

Motor Threshold Determination and Coil Positioning

Before treatment begins, your care team will perform a process called motor threshold mapping. This involves placing the TMS coil against your scalp and delivering small pulses to determine the minimum amount of energy needed to cause a slight movement in your thumb. This measurement helps calibrate the device to your individual brain anatomy, ensuring that treatment is delivered at the right intensity for you.

The treatment team will also identify the precise location on your scalp where the coil will be positioned during sessions. This careful mapping process is one of the reasons TMS can be so targeted – it allows the magnetic pulses to reach the specific brain region involved in mood regulation while leaving surrounding areas unaffected.

Weeks 1-2: Getting Started and Adjusting to Treatment

Your First Few Sessions

During the first week, you will visit Synergy of Monticello five days in a row, typically Monday through Friday. Each session follows a similar routine: you will be seated in a comfortable chair, the coil will be positioned against your scalp, and the device will deliver a series of magnetic pulses. You will hear a clicking or tapping sound during the pulses, and you may feel a tapping sensation on your scalp.

Most patients describe the sensation as unusual but tolerable. Some individuals experience mild scalp discomfort or a light headache during or after the first few sessions. These effects tend to diminish as your body acclimates to the treatment. You will remain fully awake and alert throughout each session – many patients read, listen to music, or simply relax in the chair.

What to Expect Emotionally

It is important to set realistic expectations during the early weeks. Most patients do not notice significant mood changes during the first one to two weeks of treatment. This is normal. TMS works gradually by encouraging neuroplasticity – the brain’s ability to form and strengthen new neural connections – and this process takes time. Understanding how TMS therapy works on a biological level can help you stay patient and committed during this initial phase.

Your care team at Synergy of Monticello will check in with you regularly to monitor your comfort level, adjust settings if needed, and track your progress through standardized mood assessments.

Weeks 3-4: Building Momentum

When Changes May Begin to Emerge

For many patients, weeks three and four represent a turning point. While the timeline varies from person to person, this is often when individuals begin to notice subtle but meaningful shifts in their mood, energy levels, motivation, or overall sense of engagement with daily life. Some patients report improvements in sleep quality, concentration, or the ability to experience pleasure in activities they had previously lost interest in.

These changes can be gradual and may be easier for others to notice than for the patient themselves. This is why ongoing clinical assessments during your visits are so valuable – they can help identify improvements that you may not immediately recognize on your own.

Staying Consistent

Consistency is one of the most important factors in TMS treatment outcomes. Because the therapy works by progressively strengthening neural pathways over time, missing sessions can interrupt this process. The five-day-per-week schedule is designed to maintain steady stimulation during the critical treatment window. Patients in Monticello and the surrounding areas benefit from the convenience of having a local treatment center, which helps reduce the burden of frequent visits.

If you need to reschedule a session due to illness or an emergency, your care team will work with you to adjust your schedule while keeping your treatment plan on track.

Weeks 5-6: Completing Your Treatment Course

Consolidating Gains

During the final phase of treatment, many patients experience continued improvement as the cumulative effects of TMS build on one another. The later sessions are sometimes described as a period of consolidation – reinforcing the neural changes that have been developing over the preceding weeks.

By the end of the standard treatment course, many patients report meaningful reductions in depressive symptoms. Research published in 2026 continues to support the finding that a significant percentage of patients with treatment-resistant depression experience either a substantial response or full remission following a complete course of TMS. However, results vary between individuals, and TMS does not work for everyone. Your provider will discuss your personal progress and next steps as you approach the conclusion of treatment.

Side Effects and Safety Throughout Treatment

One of the most reassuring aspects of TMS is its favorable safety profile. Because it is non-invasive and non-systemic, TMS avoids the broad side effects associated with many antidepressant medications. The most commonly reported side effect is mild scalp discomfort at the treatment site, which typically decreases over the course of treatment. Serious side effects are rare. TMS does not require anesthesia, does not cause memory loss, and does not involve any surgical procedure.

After Treatment: Maintaining Your Progress

Post-Treatment Evaluation

After completing your course of TMS, your provider at Synergy of Monticello will conduct a thorough evaluation of your progress. This assessment will compare your current symptom levels to your baseline measurements taken before treatment began. Together, you and your provider will discuss how you are feeling and determine the most appropriate path forward.

Long-Term Outlook and Maintenance

Many patients who respond to TMS experience lasting benefits, though the duration of improvement varies. Some individuals maintain their gains for many months or longer, while others may notice a gradual return of symptoms over time. If symptoms do recur, additional TMS sessions – sometimes called maintenance or re-induction sessions – may be an option. Your provider will help you develop a long-term plan that may include continued therapy, medication management, or periodic TMS sessions as needed.

Ongoing self-care practices, including regular physical activity, adequate sleep, social engagement, and talk therapy, may complement the benefits of TMS and support long-term mental health. Your treatment team can help you identify strategies that work best for your individual needs.
