One Day Isn’t the Whole Story. Ninety Days Is.
You’ve probably read about One-Day TMS: Nushama’s same-day application of accelerated intermittent theta-burst stimulation (iTBS), which compresses an entire course of brain stimulation into a single visit. It’s an applied use of the same accelerated iTBS science explored in protocols like SAINT/SNT, scheduled in a single day rather than across five. What you may not have read is what happens after you walk out of the clinic.
That’s because most coverage stops at the treatment room door. In our experience supporting people through One-Day TMS aftercare in Manhattan, the day itself is often the simpler half. The 90 days that follow (the fatigue, the waiting, the slow-then-sudden shift in mood) are where lasting change actually takes hold or quietly fades.
This guide walks through both halves: what a treatment day feels like from the inside, and the aftercare arc that turns a single day into durable healing.
Arrival: What the First Hour Feels Like
The elevator opens on the 21st floor, and most people pause. The space is intentionally quiet: soft lighting, natural textures, the deliberate absence of fluorescent panels and waiting-room televisions. It reads less like a medical office and more like a place designed to let your nervous system settle.
A care coordinator greets you by name. The first conversation isn’t about paperwork. It’s about how you slept, what you ate, whether anything feels different from your screening visit. It’s a check-in, not an intake form.
From there, the clinical team walks you through brain mapping and coil placement. In plain terms: a brief calibration determines how much magnetic energy your brain needs, and the coil is positioned over a specific spot on your left dorsolateral prefrontal cortex. This step personalizes the stimulation intensity for your neurology, not a population average.
The process takes about 30 minutes. By the time you’re seated for your first session, you’ve been in the building for roughly an hour, and the treatment day is just beginning. For a closer look at the clinical protocol, see Nushama’s One-Day TMS protocol page.
The Day Itself: A Walkthrough of the Healing Hours
One-Day TMS compresses what traditionally takes 20 to 36 daily sessions over four to six weeks into a single day of about 10 hours. The technology behind it, intermittent theta-burst stimulation (iTBS), was FDA-cleared in 2018 as a faster form of TMS. Each iTBS session lasts roughly three minutes, compared to over 37 minutes for standard repetitive TMS, a difference established in the THREE-D trial (Blumberger et al., Lancet, 2018).
Here’s how the day tends to unfold:
Morning sessions (about 8:00 a.m.–12:00 p.m.). The first few iTBS pulse trains feel like a firm, rhythmic tapping on the side of your head, unusual but not painful for most people. Each three-minute session is followed by a rest interval of about 30 minutes. Between sessions, you’re awake, alert, and free to read, listen to music, or simply sit quietly. There’s no sedation and no altered state.
Many patients describe the first sessions as “anticlimactic in the best way,” less dramatic than they expected.
Midday break. Lunch and a longer rest. Some people nap; others walk the hallway or stretch. The care team checks in on scalp comfort and adjusts cushioning if anything feels off.
Afternoon arc (about 1:00 p.m.–6:00 p.m.). Sessions continue at the same pace. By the eighth or ninth round, the tapping sensation has become background noise. Fatigue starts to accumulate, not the kind that signals something wrong, but the natural tiredness of a long, neurologically active day.
Final sessions and departure. The last session ends in the early evening. The clinical team reviews what to watch for over the next 48 hours and confirms your follow-up schedule. You walk out on your own feet, fully alert.
The scientific context: accelerated iTBS protocols build on research like the Stanford Neuromodulation Therapy (SNT) trial, which reported roughly 78.6% remission in the open-label phase and 57.1% remission versus 0% on sham in the randomized comparison, in people with severe treatment-resistant depression after five days of high-dose iTBS (Cole et al., American Journal of Psychiatry, 2022). One-day protocols compress this further, applying the same neuroplasticity principles within a single intensive day.
The First 48 Hours After Treatment
This is the window most people aren’t quite prepared for, not because it’s dangerous, but because it’s quieter than expected.
What’s typical in the first 48 hours:
- Physical fatigue from the length of the day
- Mild scalp tenderness at the stimulation site
- Variable sleep quality on the first night
- Occasionally, an unexpected emotional release (tears, a sudden tender feeling, a wave of memory), usually brief and self-resolving
- Most often: not much at all. A quiet evening, an early bedtime, a slow morning.
Practical guidance for those 48 hours:
- Stay hydrated and eat light, nourishing meals.
- Skip alcohol on Day 1.
- Avoid major life decisions for a couple of days. Your nervous system is processing.
- If possible, arrange for someone to be home with you the first evening.
- You’ll have a named contact at Nushama. Use it if anything feels destabilizing or simply unfamiliar, even just to ask “is this normal?”
The temptation to evaluate whether the treatment “worked” starts in this window. Resist it gently. What you’re feeling on Night 1 is not what you’ll feel on Day 14.
Weeks 1 Through 4: The Aftercare Arc Begins
This is where aftercare actually starts, and where continuity of care matters most.
Week 1
Variable. Some people notice a subtle lift in energy or sleep quality. Others feel no change at all. A mild dip around days 7 to 10 isn’t uncommon, a recognized pattern in accelerated stimulation research. It can feel like a temporary setback, but it typically resolves as the brain continues to rewire. The instinct to ask “Is it working?” is strongest here, and the honest answer is: it may be too early to tell.
Week 2
For many people, this is when the first real shift arrives, consistent with research showing symptom improvement typically begins two to four weeks into a TMS protocol: a morning where the heaviness lifts slightly, a conversation that feels less effortful, a task completed without the usual internal negotiation. It’s rarely dramatic. It’s more like noticing the absence of something that had been there for a long time.
Week 3
If a mood shift appeared in Week 2, it tends to consolidate here. Sleep often stabilizes. The cognitive fog that accompanies depression may begin to thin. Some people describe this week as the first time they’ve felt like themselves in months, though “themselves” can feel slightly unfamiliar at first.
Week 4
This is typically when the first formal Nushama aftercare check-in happens. The same psychiatric team that ran your treatment day reviews your symptom trajectory, screens for anything that needs adjustment, and begins planning the next phase.
Worth underscoring: at Nushama, aftercare check-ins happen with the same clinicians who were in the room with you on treatment day. There’s no handoff to a separate provider, no repeating your story to someone new. Continuity isn’t a policy line. It’s how the team is built.
The healing arc is non-linear. Some weeks feel like progress; others feel like treading water. Both are normal. What matters is that someone who knows your baseline is tracking alongside you.
Months 2 and 3: Boosters, Integration, and What’s Next
Booster sessions
Published research on accelerated iTBS suggests a meaningful number of patients benefit from at least one booster session in the four-to-eight-week window after treatment. At Nushama, the decision about whether (and when) to schedule a booster is made collaboratively, based on your symptom trajectory at the Week 4 check-in. It’s not a fixed schedule.
Integration support
Aftercare extends well beyond the stimulation itself. Psychiatric follow-ups can address sleep patterns, medication adjustments, or therapy referrals. For some people, the mood shift after TMS opens space for therapeutic work that wasn’t accessible before, and the clinical team helps coordinate that next step.
The sequencing conversation
For the smaller number of people who don’t reach full remission with TMS alone, the same psychiatric team can explore additional options, including Spravato or IV ketamine, without referring you elsewhere. Your treatment history, your aftercare trajectory, and your next step all live under the same roof. For more on how those modalities fit together, see our overview of depression treatment options and how Nushama sequences TMS and ketamine.
When to Call Between Scheduled Check-Ins
Healing is collaborative. The care team wants to hear from you between appointments, not just at them.
Reach out to your Nushama clinical contact if you experience:
- A meaningful change in mood, either downward or upward, that feels disorienting
- A sustained dip lasting more than a few days, especially after Day 10
- Sleep disruption that doesn’t resolve within a few nights
- Any thoughts of self-harm or significant hopelessness (this warrants immediate contact)
- Side effects that don’t fade: ongoing scalp tenderness, persistent headaches, anything physically uncomfortable
- A surge of energy or optimism that feels destabilizing or unfamiliar
That last point matters. A rapid lift can feel disorienting after living with depression for a long time. It’s okay to call the team and say, “Something shifted, and I’m not sure what to do with it.” That’s exactly the kind of conversation aftercare is for. Learn more about the clinical team supporting your aftercare.
What a Screening and Aftercare Planning Consultation Covers
The consultation isn’t just about determining whether you’re a fit for One-Day TMS. It’s about scoping the full 90-day arc before Day 1 even begins.
The conversation typically includes:
- Fit assessment. A psychiatric evaluation of your diagnosis, treatment history, and current symptoms, to determine whether accelerated iTBS is an appropriate option for you.
- Day-of walkthrough. What the treatment day will look like: timing, what to bring, what to arrange at home.
- Personalized 90-day aftercare plan. Your check-in schedule, booster considerations, integration support options, and sequencing pathways if your initial response suggests adding another modality.
The goal is to leave your consultation knowing not just what Day 1 looks like, but what Week 4, Week 8, and Month 3 look like, so your One-Day TMS aftercare in Manhattan is planned from the start, not figured out on the fly.

Frequently Asked Questions
How long does it take for One-Day TMS to start working?
Effects from accelerated iTBS typically unfold over one to three weeks. Many people notice their first meaningful mood shift around Week 2, with further consolidation through Weeks 3 and 4. Symptom improvement isn’t usually immediate on the day of treatment. Learn more about what to expect on Nushama’s One-Day TMS page.
What does One-Day TMS feel like during the session?
Each iTBS session lasts about three minutes and feels like a rhythmic tapping on the side of your head. You’re fully awake and alert throughout the day. Between sessions, you can rest, read, or listen to music. There’s no sedation and no altered state. See the full One-Day TMS protocol overview for more detail.
Is aftercare included at Nushama, or is it separate?
At Nushama, aftercare is built into the treatment plan. Your Week 4 check-in, booster assessments, and integration support are provided by the same psychiatric team that conducts your treatment day. There’s no referral to a separate provider. Meet the clinical team who guides your care from Day 1 through Month 3.
What side effects should I expect after One-Day TMS?
The most common effects are physical fatigue from the length of the day, mild scalp tenderness at the stimulation site, and occasionally an emotional release within the first 48 hours. According to the National Institute of Mental Health, these side effects are generally mild and self-limiting. Persistent or severe side effects should always be reported to your care team. You can reach Nushama’s clinical staff directly between scheduled visits.
How do I know if I need a booster session?
Your clinical team evaluates this at your Week 4 aftercare check-in based on your symptom trajectory. Some people sustain their improvement without a booster; others benefit from an additional session in the four-to-eight-week window. The decision is collaborative, never automatic. Book a consultation to discuss whether One-Day TMS and ongoing aftercare are the right fit for you.
