Acquired stuttering from a right hemisphere lesion in a right-hander.
Acquired stuttering in adults may follow bilateral or left hemisphere damage, is more common in men than in women, and is often associated with aphasia. After a right hemisphere infarct, a right-handed woman stuttered without aphasia. She had never stuttered previously, but her father and brother both had developmental stuttering. Her case and others suggest that sexual differences in language lateralization may render men more likely to stutter than women after left hemisphere lesions, whereas women are more likely to stutter than men after right hemisphere lesions.
