General Discussion

Landau-Kleffner syndrome is a rare neurological disorder of childhood that is characterized by the loss of the ability to understand speech and deterioration of previously acquired speech and language skills (aphasia). Most children with Landau-Kleffner syndrome also experience episodes of uncontrolled electrical disturbances in the brain (convulsive epileptic seizures). Some affected children also lose the ability to identify environmental sounds and show a general lack of attention to sounds (auditory agnosia). The exact cause of this disorder is not known. Symptoms, which develop due to brain dysfunction, vary greatly among affected individuals.
