These questions matter. Depression, anxiety, PTSD, and OCD have already cost you enough time. Nobody wants to commit to a treatment without knowing what to expect.
TMS Center Centennial has offered BrainsWay Deep TMS™ and neurofeedback in Centennial, Colorado since 2017. Over that time, patterns have emerged around how long treatment takes, when people start feeling better, and how long those improvements last. This guide walks through all of it: session length, full course duration, onset timing, and durability.
Key Takeaways
- Standard TMS runs 4-6 weeks (Deep TMS™ up to 12 with continuation); sessions last 20-40 minutes
- Most patients notice initial improvement within 2-4 weeks, though full benefits need the full course
- Results commonly last 6-12 months or longer, with maintenance available if symptoms return
- 89% of TMS Center Centennial patients see significant improvement; about 69% reach full remission
How Long Does a Full Course of TMS Therapy Take?
A standard rTMS course involves daily sessions, five days a week, for roughly 4-6 weeks, totaling 20-30 sessions. This schedule is consistent across Mayo Clinic's treatment guidance and the Clinical TMS Society's consensus recommendations.
BrainsWay Deep TMS™, the technology used at TMS Center Centennial, typically follows a longer structured course:
- Acute phase: Daily sessions, 5 days/week, for about 4 weeks
- Continuation phase: Tapered to twice weekly for another 8 weeks
- Total course length: Up to 12 weeks, meant to consolidate response before treatment ends

Session Length and Accelerated Options
Session length depends on the protocol:
- Standard Deep TMS: 20-30 minutes, often within a 45-minute appointment window
- Original rTMS pulse trains: closer to 37 minutes
- Theta Burst Stimulation (TBS): as short as 3-4 minutes per session
For eligible patients, accelerated protocols like Swift Deep TMS™ condense treatment into 1-2 weeks using multiple short sessions daily. These require careful screening; they're not a fit for everyone, but ask about them if a shorter timeline matters.
Clinical consensus points to 30-36 total sessions as the target for full symptom relief in treatment-resistant depression, according to the Clinical TMS Society's 2025 consensus statement. Course length also varies by condition: OCD protocols typically run a 6-week acute phase only, without a continuation phase.

How Long Does It Take for TMS to Start Working?
Patience matters here. Most patients begin noticing subtle changes (better sleep, more energy, a slightly brighter mood) within 2-4 weeks of starting treatment. Full results usually don't show up until the complete course is finished, since TMS effects build cumulatively with each session.
Common early signs of progress include:
- Sleeping through the night more consistently
- Sharper focus during the day
- A noticeably lighter or brighter mood
- More energy for everyday tasks
- Renewed interest in activities that felt like a chore before
One patient in a Week 1 anxiety protocol journal described waking up in a good mood by Day 3. She called it a "huge win" after struggling to get out of bed most mornings. She also found herself completing errands that usually triggered anxiety, with noticeably more motivation by the evening.
That said, individual timelines vary. TMS Center Centennial's data shows meaningful improvement typically emerging over the 4-to-6-week treatment window, aligning with a reported 89% improvement rate across depression, anxiety, OCD, and PTSD patients.
Don't stop early if week one feels uneventful. TMS is cumulative. Skipping sessions or quitting before the course is complete is one of the most common reasons people don't get full benefit.
Are TMS Therapy Results Permanent? How Long Do They Last?
Short answer: no, TMS results aren't guaranteed permanent. For most patients who finish a full course, though, they're durable.
Research from Mantovani et al. in Brain Stimulation followed remitters after acute rTMS and found event-free remission rates declining gradually without maintenance:
- 75.3% still in remission at 2 months
- 60% at 3 months
- 22.6% at 6 months

That pattern makes the 3–6 month window the period when check-ins matter most.
Response vs. Remission
These two terms get used interchangeably, but they're different:
- Response means a meaningful reduction in symptoms (often 50% or more improvement).
- Remission means symptoms are essentially resolved.
Patients who reach remission generally have more stable outcomes over the following 12 months than those who only respond.
Condition-Specific Differences
- Depression: Best-studied condition; durability data (like Mantovani's) is strongest here.
- OCD: Deep TMS is FDA-cleared, with response often maintained when paired with stable SSRI use.
- PTSD: Not yet FDA-cleared. Studies show short-term symptom reduction, but long-term durability isn't well established in large trials, so it remains investigational.
TMS Center Centennial reports 69% complete remission across its patient population. That figure isn't broken down by condition, so individual durability still depends on diagnosis, finishing a full course, and follow-up care.
What Factors Influence How Long TMS Results Last?
Several factors shape how long TMS results last:
- Age and brain plasticity: Younger patients often see more durable gains, though findings are mixed and age alone does not rule anyone out.
- Illness history: A shorter current episode before TMS often predicts a stronger, longer-lasting response.
- Course completion: Finishing the full recommended course is one of the strongest predictors of both initial success and lasting benefit.
- Ongoing support: Continued therapy or medication management, plus care for co-occurring anxiety or PTSD, helps lock in results over time.
How TMS Center Centennial Supports Lasting Results
Relief matters — and so does keeping it. TMS Center Centennial builds lasting results with a multidisciplinary approach:
- BrainsWay Deep TMS™ plus NeurOptimal® neurofeedback to reinforce brain-based gains from two angles
- Collaborative counseling with licensed therapists for the emotional and relational side of recovery
- Certified TMS technicians and a board-certified psychiatrist adjusting personalized plans to each patient’s response

Coverage matters too. Most major insurance plans, including Cigna, Anthem BCBS, TriCare, United Healthcare, and Aetna, are accepted, which helps make the full course and follow-up maintenance sessions more accessible.
Clinical Director Rodney Placzek is a retired Army Sergeant Major, so TriCare acceptance matters especially for veterans and active-duty patients.
If symptoms start to return after the initial course, maintenance or booster sessions can extend your gains — talk with your care team instead of assuming you are starting from zero.
Lifestyle Habits That Help TMS Results Last Longer
Treatment doesn't end when you walk out of your last session. A few habits support the same brain pathways TMS engages:
- Prioritize sleep: Aim for 7-9 hours nightly so brain changes can consolidate overnight
- Continue therapy or counseling: Stay in counseling alongside or after TMS to reinforce cognitive and emotional gains
- Exercise and limit alcohol: Both support the neural circuits TMS targets
- Monitor your mood: Reach out to your care team early if symptoms resurface, rather than waiting until they worsen
Frequently Asked Questions
How long should you do TMS for?
A standard course typically runs 4-6 weeks for rTMS, or up to 12 weeks for Deep TMS™ with its continuation phase. Completing the full course is essential for lasting benefit.
How often should you do TMS therapy?
Initial treatment is usually daily on weekdays, tapering to fewer sessions per week during a continuation phase. Your treating psychiatrist adjusts this based on your individual response.
How long does it take for TMS to work?
Most patients notice initial changes within 2-4 weeks, though complete results generally require finishing the full recommended course.
Are TMS therapy results permanent?
Results aren't guaranteed to be permanent, but they often last 6-12 months or longer. Maintenance sessions are available if symptoms return.
What happens if depression symptoms return after TMS?
Your psychiatrist can evaluate your symptoms and may recommend booster sessions, a maintenance schedule, or a repeat course to restore relief.
Does insurance cover TMS therapy and maintenance sessions?
Most major plans, including TriCare, typically cover standard TMS courses. Coordinating directly with the clinic helps clarify coverage for maintenance sessions specifically.
