Background: Transcranial magnetic stimulation (TMS) is a new technology for noninvasively stimulating the brain, Several studies have suggested that daily stimulation of the left prefrontal cortex with TMS for 2 weeks has probable antidepressant effects. We conducted a parallel-design, double-masked, sham-controlled study to address whether 2 weeks of daily TMS over the left prefrontal cortex has antidepressant activity greater than sham.Methods: Thirty medication-free adult outpatients with nonpsychotic, major depressive (n = 21) or bipolar (n = 9) (depressed phase) disorder who were in a current major depression (Hamilton Rating Scale for Depression [HRSD] 21-item score of >18) were treated each weekday for 2 weeks. Subjects were randomly assigned to receive either daily active (20 subjects) or sham (10 subjects) stimulation. Additionally, the 20 active subjects I were equally divided between slower (5 Hz) andfaster (20 Hz) frequency treatment. Antidepressant response was defined as greater than a 50% improvement in the baseline HRSD,Results: Active TMS resulted in significantly more responders (9/20) than did sham (0/10) (chi (2) = 6.42, p < .01), The number of responders did not differ significantly between the two active cells (3/10 faster and 6/10 slower). Expressed as a percent change from baseline, active TMS subjects had significantly greater improvement on the Beck Depression Inventory as well as the Hamilton Anxiety Rating Scale than did those who received sham.Conclusions: Daily left prefrontal TMS for 2 weeks significantly reduced depression symptoms greater than did sham, The two forms of active TMS treatment did not differ significantly, (C) 2000 Society of Biological Psychiatry.
