Localization of the Lesions in Stroke Patients with Cranial Computed Tomography and the Minnesota Classification of Aphasia

Abstract

121 stroke patients with the dominant hemispheric lesions were classified by the Minnesota classification of aphasia and investigated with CCT. 1) Euphasics (n=10) and aphasics, minimal (n=6): The small confined lesions to the basal ganglia and the internal capsule were noted. 2) Dysarthria (n=10): The lesions wers small, bilateral and scattered. 3) Group 1 (n=30): The low density areas were found in the basal ganglia, the internal capsule, F3, T1, the supramarginal gyrus etc. No predilection area was found. 4) Group 3 (n=6): The low density areas were definitely found in F3 (Broca's area) and distributed to the surrounding cortical and deeper structures. 5) Group 4 (n=6): The lesions in CCT were small and limited compared with the severity of language disturbance. 6) Group 5 (n=15): The wide spread low density areas including F3, T1, the insula, the supramarginal, the angular gyrus and the deeper structures were recognized. 7) Minor A (n=18): The low density areas of T1 (Wernicke's area) and its surrounding stracture were present. 8) Minor B (n=6): The small low density areas were found in the basal ganglia and/or the internal capsule or the frontal operculum. 9) Combined syndromes of Minor A and Group 3 (n=3): Cases of this group had the syndromes of severely affected oral language comparing written one. The site of the lesions in CT was combination of F3 and T1. 10) Others (n=11): No common site and spread of the lesions in CCT were found. © 1979, The Japan Society of Logopedics and Phoniatrics.
