Abstract

OBJECTIVE: The aim of this study was to evaluate the effects of high frequency repetitive Transcranial Magnetic Stimulation (rTMS), delivered to the dorsolateral prefrontal cortex, on selective attention in people with a bulimic disorder. METHOD: Participants (N=33) were randomised to a single session of real or sham rTMS. They performed a Stroop colour word task before and after the rTMS intervention. Interference scores were calculated as the time difference between completing cards with congruent and incongruent stimuli. RESULTS: Analysis of covariance comparing the interference scores post-rTMS with the pre-rTMS scores as covariates showed no differences between the real and sham groups [F(1,32)=1.110; p=0.301]. DISCUSSION: While methodological issues warrant a cautious interpretation, these pilot data suggest that selective attention is unaffected by a single session of rTMS.
