Landau-Kleffner syndrome (LKS), also called acquired epileptiform aphasia, is a rare, childhood neurological disorder characterized by the sudden or gradual development of aphasia (loss of language) and an abnormal electro-encephalogram (EEG). LKS affects the parts of the brain that control speech and comprehension. (Source: excerpt from NINDS Landau-Kleffner Syndrome Information Page: NINDS)
A syndrome characterized by the onset of isolated language dysfunction in otherwise normal children (age of onset 4-7 years) and epileptiform discharges on ELECTROENCEPHALOGRAPHY. Seizures, including atypical absence (EPILEPSY, ABSENCE), complex partial (EPILEPSY, COMPLEX PARTIAL), and other types may occur. The electroencephalographic abnormalities and seizures tend to resolve by puberty. The language disorder may also resolve although some individuals are left with severe language dysfunction, including APHASIA and auditory AGNOSIA. (From Menkes, Textbook of Child Neurology, 5th ed, pp749-50; J Child Neurol 1997 Nov;12(8):489-495) - (Source - Diseases Database)
Landau-Kleffner Syndrome is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Landau-Kleffner Syndrome, or a subtype of Landau-Kleffner Syndrome,
affects less than 200,000 people in the US population.
