Improved language function for post-stroke aphasia in the long term following repeated repetitive transcranial magnetic stimulation and intensive speech-language-hearing therapy: a case report

Abstract

Abstract Background There have been no papers reporting improvement in language function and changes in cerebral blood flow following repeated use of repetitive transcranial magnetic stimulation in combination with intensive speech-language-hearing therapy. This case report concerns the efficacy of repeated use of repetitive transcranial magnetic stimulation and intensive speech-language-hearing therapy for a certain patient suffering from aphasia following stroke, plus the findings of the cerebral blood flow measurements. Case presentation The patient was a 71-year-old right-handed Japanese male who developed fluent aphasia following a left middle cerebral artery stroke. He underwent repetitive transcranial magnetic stimulation and intensive speech-language-hearing therapy five times in total. The repetitive transcranial magnetic stimulation was applied to right inferior frontal gyrus at the frequency of 1 Hz plus 2 hours per day of intensive speech-language-hearing therapy. The patient’s language function was evaluated in the short term and long term. Cerebral blood flow was measured with single photon emission computed tomography scan. As a result, in the short term, the patient’s language function improved especially during the initial hospitalization. In the long term, it improved gradually and stabilized.Cerebral blood flow was increased in the right hemisphere. Conclusions The findings of the study indicate that the repeated use of repetitive transcranial magnetic stimulation and intensive speech-language-hearing therapy may be effective in improving and preserving language function and increasing cerebral blood flow for aphasia following stroke.
