Brief summary
Intermittent theta burst stimulation (iTBS), a variant of repetitive transcranial magnetic stimulation (rTMS), is a well documented method for treatment of depression. The aim of the study is to assess the effect of an accelerated iTBS protocol compared to a routine iTBS protocol. In the accelerated protocol patients will receive 1200 pulses per session (2 sessions per day, 15 treatment days) and in the routine protocol patients will receive 600 pulses per session (1 session per day, 30 treatment days). Participants (n = 146) will be recruited among patients referred to iTBS and randomized to treatment. Participants will be assessed by a psychiatrist, or a resident psychiatrist, prior to treatment to assure that they fulfill all inclusion criteria and non of the exclusion criteria. A psychiatrist, or a resident psychiatrist, will assess depressive symptoms 3 and 6 weeks after first day of treatment. Patients will complete self-rating questionnaires during screening, weekly for 6 weeks starting from the first day of treatment, and 6 months after end of treatment.
Interventions
The iTBS treatment is a type of rTMS (repetitive transcranial magnetic stimulation), delivered with MagPro R30 stimulator and a conventional cool-B65 coil. The iTBS treatment is applied to over the dorsolateral prefrontal cortex using a standardized measuring of the anatomical landmark F3 from the 10-20 positioning system. The coil is positioned with the handle at in a 45 degree angle from the midline. The centre of the butterfly is placed towards the patient head.
