What actually predicts who responds to TMS?

TMS doesn't work the same for everyone, and researchers have identified some real patterns in who responds best. None of these are guarantees — they're tendencies across large groups of patients. Age matters: a 2018 analysis of over 2,000 patients found people under 55 had response rates roughly 10-15% higher than people over 65, likely tied to how neuroplasticity changes with age. Episode length matters too — depression lasting under 2 years tends to respond better than a decade-long episode. There's a counterintuitive finding sometimes called the STAR*D paradox: patients who've failed only 1-2 medications tend to respond better to TMS than those who've failed 5 or more, even though TMS was developed specifically for treatment-resistant cases. Brain connectivity patterns — measurable on imaging — are also emerging as a strong predictor, with researchers increasingly using neuroimaging to guide treatment targeting before a course even starts. Some conditions reduce the odds: borderline personality disorder, active substance use, and psychotic features all complicate response. Others don't get in the way at all — anxiety symptoms, migraine, and chronic pain don't preclude a good outcome and sometimes improve alongside the depression. What's actually in your control: choosing an experienced provider, completing the full course, and keeping up other treatments like therapy and sleep hygiene alongside TMS. https://tmslist.com/blog/what-affects-tms-success/ Do you know how many medications you'd tried before starting TMS? Looking back, do any of these predictors match your own experience? This is general information, not medical advice.
