NIH Rare Diseases:44 Landau-kleffner syndrome (lks) is a rare, childhood neurological disorder characterized by the sudden or gradual development of aphasia (the inability to understand or express language) and an abnormal electro-encephalogram (eeg). the disorder usually occurs in children between age 5 and 7. typically, children with lks develop normally but then lose their language skills for no apparent reason. while many of the affected individuals have seizures, some do not. the disorder is difficult to diagnose and may be misdiagnosed as autism, pervasive developmental disorder, hearing impairment, learning disability, auditory/verbal processing disorder, attention deficit disorder, mental retardation, childhood schizophrenia, or emotional/behavioral problems.Ā treatment for lks usually consists of medications, such as anticonvulsants and corticosteroids, and speech therapy, which should be started early.Ā some affected children may have a permanent severe language disorder, while others may regain much of their language abilities (although it may take months or years). last updated: 12/8/2008

MalaCards: Landau-Kleffner Syndrome, also known as acquired epileptiform aphasia, is related to autistic disorder and aphasia. An important gene associated with Landau-Kleffner Syndrome is UBIAD1 (UbiA prenyltransferase domain containing 1), and among its related pathways are FSH signaling pathway and Spinal Cord Injury. The compounds 3-nitropropionic acid and glatiramer acetate have been mentioned in the context of this disorder. Affiliated tissues include brain, temporal lobe and testes, and related mouse phenotypes are cellular and normal.

NINDS:45 Landau-Kleffner syndrome (LKS) is a rare, childhood neurological disorder characterized by the sudden or gradual development of aphasia (the inability to understand or express language) and an abnormal electro-encephalogram (EEG). LKS affects the parts of the brain that control comprehension and speech. The disorder usually occurs in children between the ages of 5 and 7 years. Typically, children with LKS develop normally but then lose their language skills for no apparent reason. While many of the affected individuals have seizures, some do not. The disorder is difficult to diagnose and may be misdiagnosed as autism, pervasive developmental disorder, hearing impairment, learning disability, auditory/verbal processing disorder, attention deficit disorder, mental retardation, childhood schizophrenia, or emotional/behavioral problems.
