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 aphasi c patient. The patient had suffered from widespread ischemic damage in the area of right middle cerebral artery, with a parieto-temporal les ion. Three months post-onset he showed classical Wernicke's aphasia as sociated with oral, limb and constructional apraxia and left heminegle ct. However, follow-up findings showed a complex, dynamic pattern enti rely consistent with cognitive models of language and nonlanguage abil ities. Current models of functional brain lateralizations could not sa tisfactorily account for such longitudinal, fine-grain observations. ( C) 1994 Academic Press, Inc.
