Aphasia therapy in adults has been established to a larger extent relatively lately in the history of aphasiology, i.e. after its social medical importance had been realized and one of the cardinal problems of neurology solved more satisfactorily--lesion localization by imaging techniques. In order to evaluate the efficiency of aphasia therapy--which is still not quite uncontradicted--it was necessary to acquire sufficient knowledge of the spontaneous recovery process. It takes place--e.g. after stroke--mainly during the first 3 months, coming, as a rule, to a halt during the first year. Longer recovery periods, however, have been described. Next to etiology neurological status, overall health condition, type and severity of aphasia, and time delay between onset of the disease and start of therapy have been ascertained, whereas age and handedness seem to be of minor relevance. If syndrome change occurs the boundary between Broca's and Wernicke's aphasia is not surpassed; this taken apart almost any change from a more severe to a milder form of aphasia is possible. To isolate the therapeutic effect from spontaneous recovery in larger groups is difficult. There are, however, more recent investigations which suggest, that a correctly indicated therapy, which is sufficiently intensive and lasts long enough, will be effective. One of the corner-stones of any therapeutic effort ist adequate stimulation, oriented toward the patients needs and his aphasic syndrome, and taking into account the systemic nature of language and its most important linguistic structural components. Furthermore, a phase-specific and interdisciplinary approach and integration of closely related persons play an important role. We divide the numerous therapeutic techniques into 3 groups: direct or stimulation approach, indirect or circumventory approach, compensatory or alternative strategies approach. Representatives of all 3 groups are presented briefly, e.g. auditory stimulation, divergent semantic intervention, promoting aphasics communicative effectiveness, language enrichment therapy, programmed instruction; then the deblocking method, melodic intonation therapy, imagery, a sample of linguistically oriented methods for the reeducation of syntax, semantics, and phonemics along with special methods for the treatment of alexia and agraphia; finally compensatory techniques like visual communication, visual action therapy, and bliss symbolics. Some particular problems encountered in working with aphasics are addressed. A point is made about the feasibility and profit of lay therapy.(ABSTRACT TRUNCATED AT 400 WORDS)
