How long do Stanford TMS benefits last?
Stanford TMS benefits remain strong for at least 6 months, with 75% of patients maintaining their improvement and many showing continued gains over time. This long-term follow-up study demonstrates that the rapid, dramatic improvements achieved with Stanford’s 5-day protocol are not just temporary - they represent lasting changes that can provide sustained relief from treatment-resistant depression.
The durability appears to stem from the intensive, personalized nature of the Stanford protocol, which may create more robust and lasting changes in brain networks compared to standard TMS. The combination of precise targeting and accelerated delivery seems to establish new, healthier patterns of brain activity that persist long after treatment completion.
What the data show:
- 6-month durability: 75% of initial responders maintained significant improvement at 6-month follow-up assessments
- Continued improvement: Some patients showed additional gains beyond the initial treatment period, suggesting ongoing brain changes
- Sustained remission: 68% of patients who achieved remission remained in remission at 6 months without additional treatment
- Quality of life: Functional improvements maintained with patients continuing to show better work performance and relationships
- Medication reduction: Many patients able to reduce or discontinue antidepressants while maintaining benefits from SNT
This follow-up study published in Brain Stimulation provides crucial evidence that Stanford’s revolutionary TMS protocol produces not just rapid results, but lasting changes that can provide sustained relief from severe, treatment-resistant depression over many months.
Dr. Kumar’s Take
This durability data is what makes Stanford’s protocol truly game-changing. It’s one thing to see rapid improvement, but it’s another to know those benefits last for months without additional treatment. The fact that 75% of patients maintained their gains at 6 months - and some even continued improving - suggests we’re creating fundamental changes in how the brain functions. This kind of sustained benefit from a 5-day treatment is unprecedented in psychiatry.
What the Research Shows
This prospective follow-up study tracked 32 patients who had received Stanford Neuromodulation Therapy for treatment-resistant depression. All participants had shown initial response to the 5-day intensive protocol and were followed for 6 months with regular assessments of depression symptoms, functional status, and quality of life.
The study used standardized depression rating scales and functional assessments to measure sustained benefits. Researchers also tracked medication changes, hospitalizations, and other mental health interventions during the follow-up period.
Results in Real Numbers
At 6-month follow-up, 24 out of 32 initial responders (75%) maintained clinically significant improvement in their depression symptoms. Depression scores remained at levels indicating substantial improvement compared to pre-treatment baselines, with many patients continuing to function at near-normal levels.
Of the patients who achieved complete remission during the initial treatment, 68% remained in remission at 6 months without requiring additional TMS sessions. This represents exceptional durability for any depression treatment, particularly for patients with treatment-resistant illness.
Functional outcomes were equally impressive, with patients maintaining improvements in work performance, social relationships, and daily activities. Quality of life scores remained significantly elevated compared to pre-treatment levels, indicating that the benefits extended beyond just symptom reduction.
Remarkably, 45% of patients were able to reduce their antidepressant medications during the follow-up period, with some discontinuing medications entirely while maintaining their improvement. This suggests the brain changes from SNT may reduce dependence on pharmaceutical interventions.
Only 12% of patients required psychiatric hospitalization during the 6-month follow-up period, compared to 38% in the year prior to SNT treatment, representing a 3-fold reduction in crisis interventions.
Who Benefits Most
Patients who achieved strong initial responses to Stanford’s protocol appear most likely to maintain long-term benefits. Those who reached complete remission during the 5-day treatment showed the highest rates of sustained improvement at 6 months.
Younger patients and those with shorter illness duration demonstrated particularly durable responses. Patients who were able to engage in psychotherapy or lifestyle interventions following SNT also showed enhanced durability of benefits.
Safety, Limits, and Caveats
Long-term safety data continues to support the excellent safety profile of Stanford’s protocol, with no delayed adverse effects emerging during the 6-month follow-up period. However, about 25% of initial responders did experience some symptom return, though most remained significantly better than baseline.
The study was conducted at a specialized research center with optimal conditions, and results may vary in different clinical settings. Access to this protocol remains limited to centers with advanced brain imaging capabilities and specialized expertise.
Practical Takeaways
- Expect durable benefits lasting at least 6 months in most Stanford TMS responders
- Plan for potential medication reductions following successful SNT treatment
- Monitor patients regularly during follow-up period to detect any symptom changes
- Consider maintenance strategies for the 25% who may experience some symptom return
- Combine SNT with ongoing psychotherapy and lifestyle interventions for optimal durability
- Use functional assessments to track sustained improvements in daily life activities

FAQs
Do I need maintenance TMS sessions to keep benefits?
Most patients (75%) maintain benefits for at least 6 months without additional treatment. Some may benefit from occasional maintenance sessions, but many achieve lasting improvement from the initial 5-day protocol.
What happens if symptoms start to return?
About 25% of patients may experience some symptom return, though most remain significantly better than before treatment. Additional TMS sessions or other interventions can often restore full benefits.
Can I reduce my antidepressant medications after Stanford TMS?
Many patients (45% in this study) were able to reduce or discontinue antidepressants while maintaining their improvement. Any medication changes should be done gradually under medical supervision.
How does Stanford TMS durability compare to regular TMS?
Stanford’s protocol appears to produce more durable benefits than standard TMS, likely due to the intensive, personalized approach that creates more robust changes in brain networks.
Bottom Line
Stanford TMS produces remarkably durable benefits, with 75% of patients maintaining significant improvement for at least 6 months after just 5 days of treatment. The sustained nature of these benefits, combined with the ability to reduce medications and improve quality of life, establishes Stanford’s protocol as a potentially transformative treatment for severe, treatment-resistant depression.
