Is this trial a fit for you?

Likely a good fit

Adults with a diagnosed depression who are indicated for TMS and able to provide informed consent.

Probably not a fit

Patients with contraindications to TMS or those unlikely to complete follow-up may not benefit.

What this trial studies

This observational study will evaluate the effectiveness and tolerability of an accelerated iTBS protocol delivered in standard clinical settings. Participants receive 600 stimulation pulses per session, totaling 30 sessions over 5 to 14 treatment days, with follow-up assessments up to 6 months from start. Patients are monitored through self-rating questionnaires at screening, before and after treatment, and at 6 weeks, 12 weeks, and 6 months. Inclusion requires a depression diagnosis confirmed by MINI and suitability for TMS, while major exclusions relate to ferromagnetic implants or other factors increasing follow-up risk. The study is conducted across multiple hospitals in Sweden and aims to enroll up to 150 patients, with a target of at least 36 participants.

Why it matters

Potential benefit: If successful, accelerated iTBS could shorten treatment time while maintaining benefit for depression.

How similar studies have gone: Previous iTBS research supports effectiveness in depression, but accelerated protocols in routine care are being explored and may yield varied results.
