Severe stuttering associated with right hemisphere lesion.
Following a right hemisphere stroke, a right-handed, 50-year-old male experienced a permanent dysfluency characterized by phoneme and syllable reiterations and, to a lesser extent, word and phrase reiterations. The reiterations occurred in initial, medial, and final positions and for all sentence elements (e.g., subject nouns, object nouns, verbs, modifiers). There was a notable loss of verbal automatisms (poems, songs, etc.). The patient's symptoms conform to the acquired stuttering syndrome described by A. Helm, R. Butler, and D.F. Benson (1978, Neurology, 28, 1159-1165).
