 The mainstream method for repetitive transcranial magnetic stimulation (rTMS) treatment for aphasia aims to activate the language field of the dominant hemisphere by suppressing the contralateral hemisphere in a disinhibited state using low-frequency stimulation (0.5-2Hz). There are no reports of long-term improvement resulting from activation of the contralateral hemisphere using high-frequency stimulation (5Hz<) to promote compensation of language function. The present case has chronic aphasia due to extensive damage to the left hemisphere. Observation under fMRI revealed that during language tasks the right hemisphere was predominantly activated. For two weeks, the patient received high-frequency rTMS treatment to the right hemisphere twice a day, each time followed by 1-hour speech-language therapy and self-study period. The two-week treatment was repeated after one year and his language function was found to have improved gradually over the year. From this result, it is considered that in cases where the dominant hemisphere is severely damaged, it is effective to directly activate the compensatory site with high-frequency rTMS.
