Comparison of metabolic rates, language, and memory in subcortical aphasias. [Tomographic studies using /sup 18/F-fluorodeoxyglulcose]
Four patients with subcortical lesions and either aphasia or amnesia were compared to four patients with cortical lesions and aphasia. Each patient had /sup 18/F-fluorodeoxyglucose positron emission computed tomography and language and memory evaluations. Metabolic depression was found in the thalamus and caudate in both groups, while only the cortical group showed cortical changes. Language changes were mild in the subcortical, while moderate to severe in the cortical group. Both groups showed severe verbal memory dysfunction. The only common abnormalities in the two groups were metabolic changes in thalamus, and severity of verbal memory dysfunction. These findings suggest a relationship between verbal memory and thalamic function.
