Abstract

    About communication disorders of acquired childhood higher brain dysfunction, the clinical picture of acquired childhood aphasia (ACA) , childhood auditory agnosia due to bilateral auditory cortices (AA) and Landau-Kleffner syndrome (LKS) were reported.<br>   The traditional description of the clinical picture of ACA claims that ACA is invariably nonfluent, that recovery of language disorder is rapid and complete, and that ACA commonly occurs after right hemisphere damage. However, since the late 1970s the publication of several case studies has led to reject this longstanding standard doctrine. This review, which concerns the revised insights into ACA, aims at making an inventory of the recently described aphasic symptomatologies and neuroradiological data. Recent case studies show a great variety of aphasic symptomatologies including auditory comprehension disorders, paraphasias, neologisms, logorrhea, jargon, impaired repetition abilities, and a host of linguistic deficits in reading and writing. Not only the aphasic typology but also the recently established clinicoradiological correlations appear to resemble those found in adults. Also, recovery from ACA shows to be less complete than previously thought.<br>   AA is a rare disorder characterised by loss of speech discrimination and auditory comprehension in spite of normal hearing. Most children were afflicted with herpes simplex encephalitis. Sign language is helpful for children with auditory agnosia, because they can not develop normal auditory perception.<br>   LKS was first described in 1957. The disorder is characterised by gradual or rapid loss of language in a previously normal child. All children have abnormal EEG compatible with the diagnosis of epilepsy. However, only 70% have clinical seizures. The present article presents a review of the current knowledge concerning this disorder.<br>   It is necessary to provide an appropriate language education and also long-term follow up for each child with acquired higher brain dysfunction.
