Abstract

A 48-year-old patient who had aphasia due to a left subcortical hemorrhage underwent three follow-up examinations to assess MR signal changes accompanying recovery. A word classification task was applied. During the 6-month follow-up period, we observed a dynamic change from negative toward positive blood oxygenation level-dependent MR signals, i.e., task-related reafferentation of eloquent cortices occurred. Clinical improvement from aphasia paralleled the MR signal changes.
