Impairment of written language and mathematical skills in a case of Landau-Kleffner syndrome

Abstract

A girl who developed Landau-Kleffner syndrome when she was 8 years and 6 months old, is described. Generally, the clinical picture of the aphasia in this syndrome consists in a severe reduction of comprehension followed in time by an impairment of production; written language is usually better preserved. In this case the patient showed an unusual pattern of language disorders including a severe impairment of written tasks, and a dyscalculic deficit which is studied in detail. These two neuropsychological problems are discussed.
