Abstract:	Background. Studies of repetitive transcranial magnetic stimulation (rTMS) in depression have mostly involved once-daily treatment, with positive but modest clinical results. This study tested the efficacy and safety of twice-daily rTMS over 2 weeks.Method. Thirty-eight depressed subjects enrolled in a double-blind, sham-controlled trial of twice-daily rTMS (left prefrontal cortex, 10 Hz, 110% intensity, 1500 stimuli per session) over 2 weeks. Mood and neuropsychological functioning were assessed weekly by blind raters, using the Montgomery-Asberg Depression Rating Scale (MADRS) as the primary outcome measure, plus the Hamilton Rating Scale for Depression (HRSD) and self-report measures. After the blind period, 22 subjects continued with once-daily rTMS to receive a total of 6 weeks of active rTMS.Results. Subjects were moderately treatment resistant. Active treatment resulted in significantly greater improvement than sham over the 2-week blind period on one outcome measure only (MADRS p<0.05). Subjects showed further improvement over the 6 weeks of active rTMS. Neuropsychological test scores did not change significantly.Conclusions. rTMS given twice daily was effective and safe, with no adverse neuropsychological effects. [ABSTRACT FROM AUTHOR]
