What to expect during and after TMS - a realistic timeline from your first session to six weeks out
What to expect during and after TMS - a realistic timeline from your first session to six weeks out
One of the most common reasons patients feel discouraged after starting TMS is a mismatch between what they expected and what actually happens. They finish their protocol, go home, and feel essentially the same as they did when they walked in. They conclude that TMS didn't work.
Often, it's working. It just hasn't finished yet.
This article is our attempt to give you the most honest, complete picture of what TMS treatment actually looks like, from the day you arrive to the weeks that follow, so that you go in with accurate expectations and don't abandon the process before it has a chance to complete.

Before you arrive: the consultation
Before any treatment begins, you'll have a consultation with Thomas Tervort, DNP. This isn't a sales conversation, it's a clinical one.
You'll discuss your diagnosis, your treatment history, what you've tried before and how it went, your goals, and any medical history relevant to TMS candidacy. Thomas will ask about metal implants, seizure history, current medications, and other factors that affect treatment safety and protocol selection.
You'll also have the opportunity to ask every question you have. What will it feel like? How will I know if it's working? What should I do during the treatment window? What happens if I don't respond?
We'd rather you arrive on treatment day with complete clarity than arrive with anxiety about what you've signed up for. The consultation is where that clarity gets built.
Your treatment day: what the sensation is actually like
Whether you're doing the One-Day Intensive, the Five-Day Intensive, or the traditional six-week protocol, the experience of each individual TMS session is similar.
You'll be seated in a comfortable reclining chair. A magnetic coil will be positioned against your scalp over the target region for most protocols treating depression, this is the left side of your head, above and slightly forward of your ear. The coil will be held in place and you'll be asked to remain relatively still during stimulation.
When the stimulation begins, you'll feel a rhythmic tapping or knocking sensation on your scalp. Some patients describe it as a woodpecker. Some describe it as someone firmly tapping with two fingers in a rapid, regular pattern. There's often a mild sensation in the scalp muscles a slight tightening or pulsing and some patients notice a faint sound or vibration sensation in the jaw or teeth, particularly in early sessions.
It's unusual. For most patients it isn't painful. For some patients, particularly in the first few sessions, it's uncomfortable the scalp is adapting to a stimulus it hasn't experienced before. Mean discomfort in the ONE-D trial was rated 5.8 out of 10 across a full day of twenty sessions. That's honest: it's noticeable, not trivial, and for most patients it becomes significantly more comfortable after the first day or two as adaptation occurs.
What it isn't: painful in a sharp or alarming way for most patients, sedating, disorienting, or anything like an electrical shock. You will be awake and alert throughout. You can talk, listen to music, watch something on your phone between sessions, or simply rest. You will be able to drive home afterward.
Headache is the most commonly reported side effect typically mild, resembling a tension headache, and resolving within a few hours of treatment. It tends to diminish over the course of treatment. Scalp discomfort at the stimulation site is also common early on and improves with time.
Serious adverse events are rare. The estimated seizure risk with properly administered TMS is approximately 1 in 30,000 sessions lower than the risk associated with many common medications.
The most important thing to understand: TMS is slow to show its work
Here is where patient expectations most commonly diverge from reality and where that divergence causes the most unnecessary distress.
TMS does not work like a medication that's in your system and producing an effect. It works by inducing neuroplastic changes in brain circuits structural rewiring that takes time to consolidate even after the last session is complete. The brain doesn't change overnight. It changes gradually, over weeks, as the synaptic potentiation TMS induces gets reinforced and stabilized.
For most patients, the response trajectory looks something like this:
During treatment or immediately after: Little to no noticeable mood change. Some patients report feeling slightly more fatigued. Some report a brief period of feeling flat or even slightly worse in the first week or two this is a known phenomenon and does not indicate that treatment isn't working. It reflects the early phase of circuit reorganization, not failure.
Weeks one and two post-treatment: Most patients still notice little change. This is the period where patients most commonly conclude that TMS didn't work for them. It is also, for most patients, simply too early to tell.
Weeks three and four post-treatment: This is where the majority of patients begin noticing meaningful change. Sleep often shifts first improving in quality or duration before mood changes become obvious. Energy levels and motivation frequently shift before subjective mood does. Small things become easier before large things do.
Weeks four through six post-treatment: Peak response for most patients. The neuroplastic changes TMS initiated have had time to consolidate. Circuits that were underactive are firing more reliably. The prefrontal regulation of the limbic system the top-down control of emotional reactivity that chronic stress and depression disrupt is more functional.
Beyond six weeks: For many patients, improvement continues beyond this window. The neuroplasticity changes TMS induces don't stop consolidating the moment you hit the six-week mark. Some patients continue improving into months two and three.
The practical implication of all of this: if you finish your TMS protocol and feel essentially unchanged at day seven, you have not yet reached the point where most patients see results. The process is not done. Give it time.
The neuroplasticity window: what happens after treatment matters as much as the treatment itself
This is the concept we want to spend the most time on, because it's the one most patient-facing TMS content gets wrong by omission.
TMS doesn't just produce antidepressant effects directly. It creates conditions, specifically, a period of heightened neuroplasticity during which the brain is unusually capable of change. The treatment opens a window. What you do in that window determines how completely and durably your brain takes advantage of it.
Think of it this way. Depression involves circuits that have become dysregulated patterns of activity and connectivity that have gotten stuck. TMS disrupts those stuck patterns and makes the relevant circuits more plastic, more responsive, more capable of reorganizing. But reorganizing into what? That depends, in part, on what you're doing.
Therapy becomes more effective. This is one of the most clinically significant and underappreciated aspects of the post-TMS window. Cognitive behavioral therapy, EMDR, exposure and response prevention for OCD, prolonged exposure for PTSD these approaches work by promoting new patterns of thinking, processing, and responding. They require the brain to form new associations and strengthen new circuits. All of that is neuroplasticity. And TMS-elevated neuroplasticity means your brain is more capable of doing that work than it was before treatment.
For patients who have tried therapy in the past and found it helpful but insufficient, this is worth sitting with. The therapy may not have been wrong. The brain's capacity to fully integrate and consolidate what therapy was trying to do may have been limited by the very circuit dysfunction that therapy was trying to address. TMS changes that equation.
For patients who have tried therapy and found it largely ineffective, the post-TMS window is an opportunity to try again with a brain that is meaningfully more neuroplastic than it was before. Approaches that didn't work before may work now. This isn't a guarantee, but it's a genuine clinical rationale for re-engaging with therapeutic work during and after TMS rather than treating TMS as a standalone intervention.
Behavioral activation amplifies the effect. Neuroplasticity is activity-dependent, the brain wires toward what it's doing. During the post-TMS window, behavioral choices matter more than usual. Exercise promotes neuroplasticity directly, through BDNF release and hippocampal neurogenesis. Sleep is when synaptic consolidation happens, the structural changes TMS initiated get stabilized during deep sleep. Social engagement, meaningful activity, and goal-directed behavior all reinforce the circuit patterns TMS is trying to strengthen.
Conversely, alcohol disrupts neuroplasticity and interferes with synaptic consolidation. Isolation and behavioral withdrawal reinforce the very circuit patterns that depression produces. Passive waiting sitting and hoping the TMS works while continuing everything exactly as before is a missed opportunity.
We are not suggesting that patients need to perfectly optimize every lifestyle variable to benefit from TMS. Many patients achieve significant results without dramatically changing their daily lives. But we are saying that the post-TMS window is a genuinely elevated opportunity for change and that treating it as such tends to produce better outcomes.
Medication may work better. For patients currently on antidepressants that are partially effective, TMS frequently enhances their effect. The circuit-level changes TMS produces can make previously inadequate medication regimens suddenly more effective. If you're on medication, don't discontinue it without discussing it with your prescriber and don't be surprised if your existing medication feels like it's working better in the weeks following TMS.
For patients not currently on medication, the post-TMS window is also a reasonable time to consider whether medication augmentation makes sense for your situation. Our PMHNP-BC provides medication management in-house if that conversation is relevant for you, we're here for it.
What non-response looks like and what to do about it
We've written elsewhere about this honestly, but it bears repeating here: TMS doesn't work for everyone. Published response rates for accelerated protocols are high but they are not 100%. Some patients complete a full protocol and do not achieve meaningful improvement.
The most reliable signal that TMS is not producing a response is an absence of any meaningful change in sleep, energy, motivation, mood, or subjective experience by weeks five or six post-treatment. Earlier than that is simply too early to draw conclusions.
If you reach that point without meaningful change, the conversation doesn't end there. Our team can work with you on next steps reassessing your medication regimen, discussing whether a different protocol might produce a different response, or identifying other evidence-based options. We're not a one-treatment clinic, and we won't send you home without a path forward.
What we won't do is tell you at week two that TMS didn't work. That conclusion, at week two, is almost always premature.
A practical checklist for the post-TMS window
To make this as actionable as possible:
Continue or start therapy. If you have an existing therapist, tell them you've just completed TMS and that you're in an elevated neuroplasticity window. A good therapist will understand what that means and may adjust the intensity or focus of your work accordingly. If you don't have a therapist, consider this the right time to find one. We offer talk therapy in-house if you need a starting point.
Protect your sleep. Aim for seven to nine hours. Keep a consistent schedule. This is when consolidation happens. Sleep disruption during the post-TMS window is the most direct way to undermine the structural changes underway.
Move your body. Daily exercise even walking promotes BDNF release and supports neuroplasticity. You don't need to run a marathon. You need to not be sedentary.
Minimize alcohol. Alcohol suppresses NMDA receptor activity the same receptor pathway that D-cycloserine in the ONE-D protocol specifically activates. It interferes with synaptic consolidation. Complete abstinence isn't required for most patients, but this is not the period to drink heavily.
Engage, don't withdraw. Depression pulls toward isolation and inactivity. The post-TMS window is precisely when engaging with people, with activities, with meaning most powerfully reinforces the circuit changes underway.
Be patient with the timeline. Write down how you feel the day after your last session. Check in with yourself at two weeks, four weeks, and six weeks. The trajectory often isn't visible until you compare across time rather than assessing day by day.
Stay in contact with us. We want to know how you're doing. If something feels off increased anxiety, significant mood swings, anything that concerns you reach out. We're here throughout the post-treatment period, not just during it.
