[Rehabilitation prognosis of aphasias of various etiologies with reference to clinical, neurolinguistic and computerized tomography findings].

: To obtain further insights into the rehabilitation outlook in different baseline conditions, a comparison was made of data and treatment outcomes in 92 patients having aphasias of different etiology and disease duration. Rating as "improved" was contingent on significant changes in at least 2 subtests of the AAT (Aachener Aphasietest), which is a fairly stringent requirement. This criterion was met by some 35% of the patients overall, independent of their age; the percentage increased to 45% in case of treatment onset during the first year, while in later onset, significant improvement was achieved in 15% only. Aphasic syndromes secondary to hemorrhage, trauma, tumors, or infections, usually are less severe than the predominant classical syndromes, i.e. Global, Broca and Wernicke aphasia, caused by ischemic stroke. CT lesion size did not yield any definite information. Minor improvements below the required significance levels, and, above all, gains in communication performance, i.e. further consolidation, could be achieved by appropriate management even after the crucial initial year, which, however, does not imply any fundamental changes in the rehabilitation prognosis as such.
