Factors influencing type and severity of aphasia

Abstract

The influence of etiology and sex on aphasia type and the relation of age to the severity and type of language disorders have been assessed in 718 right-handed aphasic patients. Both trauma and neoplasia are associated with fluent aphasia significantly more often, while sex proved to have no influence on aphasia type. The frequency distribution of age according to type and severity of aphasia - studied in vascular patients only (N = 566) - demonstrated that fluency and severity are significantly associated with older age.
