PATTERNS OF RECOVERY AND CHANGE IN VERBAL AND NONVERBAL FUNCTIONS IN A CASE OF CROSSED APHASIA - IMPLICATIONS FOR MODELS OF FUNCTIONAL BRAIN LATERALIZATION AND LOCALIZATION

We present a 2-year verbal and nonverbal follow-up of a crossed aphasic patient. The patient had suffered from widespread ischemic damage in the area of right middle cerebral artery, with a parieto-temporal lesion. Three months post-onset he showed classical Wernicke's aphasia associated with oral, limb and constructional apraxia and left hemineglect. However, follow-up findings showed a complex, dynamic pattern entirely consistent with cognitive models of language and nonlanguage abilities. Current models of functional brain lateralizations could not satisfactorily account for such longitudinal, fine-grain observations. (C) 1994 Academic Press, Inc.
