['Transcranial direct current stimulation (tDCS) is an effective approach to modulate brain region functions. We assessed if a single tDCS session over the bilateral frontal-parietal-temporal (FPT) areas would reduce cue induced craving in heroin addicts.', 'Twenty non-treated, long-term heroin-addicted subjects were randomly assigned to receive either real tDCS (1.5\xa0mA, cathodal over bilateral FPT for 20\xa0min) or control tDCS stimulation (turning off the stimulation after 30\xa0s). The participants received heroin cue exposure (containing both injection and inhalation procedures) before and after stimulation and rated their craving after each block of cue presentation.', 'Stimulation of the bilateral FPT with real tDCS for 20\xa0min reduced craving scores significantly (68\xa0±\xa08.4 pre-stimulation vs. 43\xa0±\xa07.6 post-stimulation, p\xa0=\xa00.003), while the control stimulation group showed no significant changes. No side effects of tDCS were reported.'] Does transcranial direct current stimulation of the frontal-parietal-temporal area attenuate cue-induced craving for heroin?
