| Outline of Final Research Achievements |
Transcranial direct current stimulation (tDCS) is known to non-invasively alter cortical excitability, and has been reported to enhance language function not only in aphasia patients but also in normal speakers. In this study, we performed transcranial direct current stimulation (tDCS) to an adult who stutter and observed changes of his speech fluency during conversation. In addition to speech dysfluency, the subject exhibited abnormal language processing in the measure of ERP. The anode electrode was attached to Broca's area and the cathode electrode was attached to the right orbital part. Stimulation at 2 mA for 20 minutes was performed twice with an interval of 1 week. Results of the study revealed no change in the subject’s speech dysfluency. Further research was strongly required.

| Academic Significance and Societal Importance of the Research Achievements |
近年、脳卒中のリハビリテーションや精神疾患の治療において、侵襲性のないｔDCSなどが、ニューロリハビリテーションとよばれ注目されている。本研究は、治療法が確立されていない吃音の治療にtDCSが効果があるかどうかを検証することが目的であった。しかし、本研究では、吃音の治療にｔDCSが効果があることは確認できなかった。ニューロリハビリテーションの手法が吃音の改善に効果があることの発見は、吃音者にとって大きな福音となると考えられることから、今回の結果を踏まえ、さらなる検討が必要であると考えられた。
