Abstract

Although repetitive transcranial magnetic stimulation (rTMS) for hemiparesis is beneficial, so far no study has examined the usefulness of rTMS for apathy. Thirteen patients with chronic stroke were assigned randomly to 2 groups: rTMS group (n = 7) and sham stimulation group (n = 6). The patients received 5 sessions of either high-frequency rTMS over the region spanning from the dorsal anterior cingulate cortex (dACC) to medial prefrontal cortex (mPFC) or sham stimulation for 5 days. The severity of apathy was evaluated using the Apathy Scale (AS) and the severity of depression was evaluated using the Quick Inventory of Depressive Symptomatology (QIDS) serially before and after the 5-day protocol. The AS and QIDS scores were significantly improved in the rTMS group, although they were not changed in the sham stimulation group. The degree of change in the AS score was significantly greater in the rTMS group than that in the sham stimulation group. The degree of change in the QIDS score was greater in the rTMS group than that in the sham stimulation group, although the difference was not statistically significant. The application of high frequency rTMS over the dACC and mPFC may be a useful intervention for apathy due to stroke.
