Summaries for Landau-Kleffner Syndrome

NIH Rare Diseases : 50 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 2 and 8. 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, intellectual disability, childhood schizophrenia, or emotional/behavioral problems. treatment for lks usually consists of medications, such as anticonvulsants and corticosteroids, and speech therapy, which should be started promptly. the prognosis varies. some children may have a permanent language disorder, while others may regain much of their language abilities (although it may take months or years). last updated: 4/13/2015

MalaCards based summary : Landau-Kleffner Syndrome, also known as acquired epileptiform aphasia, is related to epilepsy, focal, with speech disorder and with or without mental retardation and epilepsy-aphasia spectrum, and has symptoms including seizures An important gene associated with Landau-Kleffner Syndrome is NDUFS4 (NADH:Ubiquinone Oxidoreductase Subunit S4). The drugs Acetazolamide and Diazepam have been mentioned in the context of this disorder. Affiliated tissues include brain, temporal lobe and testes, and related phenotypes are Increased shRNA abundance (Z-score > 2) and integument

NINDS : 51 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, childhood schizophrenia, or emotional/behavioral problems.
