• A 58-year-old, right-handed man became aphasic following a left-hemisphere stroke. Despite the massive size of the lesion, the aphasia was transient. An apraxia and agraphia did, however, persist three years after onset. The pattern of language impairment and subsequent recovery is believed to represent the rarely documented condition of mixed cerebral dominance for language.
