Summaries for Lennox-Gastaut Syndrome

Genetics Home Reference : 25 Lennox-Gastaut syndrome is a severe condition characterized by recurrent seizures (epilepsy) that begin early in life. Affected individuals have multiple types of seizures, a particular pattern of brain activity (called slow spike-and-wave) measured by a test called an electroencephalogram (EEG), and impaired mental abilities. In Lennox-Gastaut syndrome, epilepsy begins in early childhood, usually between ages 3 and 5. The most common seizure type is tonic seizures, which cause the muscles to stiffen (contract) uncontrollably. These seizures typically occur during sleep; they may also occur during wakefulness and cause sudden falls. Also common are atypical absence seizures, which cause a very brief partial or complete loss of consciousness. Additionally, many affected individuals have episodes called drop attacks, which cause sudden falls that can result in serious or life-threatening injuries. Drop attacks may be caused by sudden loss of muscle tone (described as atonic) or by abnormal muscle contraction (described as tonic). Other types of seizures have been reported less frequently in people with Lennox-Gastaut syndrome. Seizures associated with Lennox-Gastaut syndrome often do not respond well to therapy with anti-epileptic medications. Although each seizure episode associated with Lennox-Gastaut syndrome is usually brief, more than two-thirds of affected individuals experience prolonged periods of seizure activity (known as status epilepticus) or episodes of many seizures that occur in a cluster. Most children with Lennox-Gastaut syndrome have intellectual disability or learning problems even before seizures begin. These problems may worsen over time, particularly if seizures are very frequent or severe. Some affected children develop additional neurological abnormalities and behavioral problems. Many also have delayed development of motor skills such as sitting and crawling. As a result of their seizures and intellectual disability, most people with Lennox-Gastaut syndrome require help with the usual activities of daily living. However, a small percentage of affected adults live independently. People with Lennox-Gastaut syndrome have a higher risk of death than their peers of the same age. Although the increased risk is not fully understood, it is partly due to poorly controlled seizures and injuries from falls.

MalaCards based summary : Lennox-Gastaut Syndrome, also known as epileptic encephalopathy lennox-gastaut type, is related to seizure disorder and early infantile epileptic encephalopathy, and has symptoms including hemiplegia An important gene associated with Lennox-Gastaut Syndrome is SCN1A (Sodium Voltage-Gated Channel Alpha Subunit 1), and among its related pathways/superpathways are GABAergic synapse and Neuroscience. The drugs Clobazam and Melatonin have been mentioned in the context of this disorder. Affiliated tissues include brain, testes and eye, and related phenotypes are intellectual disability and encephalopathy

Disease Ontology : 12 A childhood electroclinical syndrome that is characterized by frequent seizures and intellectual disability that present in early childhood.

NIH Rare Diseases : 52 Lennox-Gastaut syndrome is a form of severe epilepsy that begins in childhood. It is characterized by multiple types of seizures and intellectual disability . This condition can be caused by brain malformations, perinatal asphyxia (lack of oxygen), severe head injury, central nervous system infection and inherited degenerative or metabolic conditions. In about one-third of cases, no cause can be found. Treatment for Lennox-Gastaut syndrome includes anti-epileptic medications such as valproate , lamotrigine , felbamate , or topiramate . There is usually no single antiepileptic medication that will control seizures. Children may improve initially, but many later show tolerance to a drug or develop uncontrollable seizures.

NINDS : 53 Lennox-Gastaut syndrome is a severe form of epilepsy. Seizures begin in early childhood, usually before the age of 4 years. Children, adolescents, and adults with Lennox-Gastaut syndrome have multiple types of seizures that vary among individuals. Common seizure types include: tonic seizures (stiffening of the body, upward eye gaze, dilated pupils, and altered breathing patterns) atypical absences (staring spells) atonic seizures (brief loss of muscle tone, which could cause abrupt falls) myoclonic seizures (sudden muscle jerks), and generalized tonic-clonic seizures (muscle stiffness and rhythmic jerking). There may be periods of frequent seizures mixed with relatively seizure-free periods. Although not always present at the onset of seizures, most people with Lennox-Gastaut syndrome experience some degree of impaired intellectual functioning or information processing, along with developmental delays and behavioral disturbances. A particular patten of brain electric activity can be seen using electroencephalogram (EEG). Lennox-Gastaut syndrome can be caused by a variety of conditions, including brain malformations, tuberous sclerosis, perinatal asphyxia, severe head injury, central nervous system infection, and inherited genetic and inherited degenerative or metabolic conditions. In 30-35 percent of individuals, no cause can be found.

KEGG : 36 Lennox-Gastaut syndrome (LGS) is an epileptic encephalopathy characterized by multiple seizure types, typical findings in the electroencephalogram (EEG), and delayed psychomotor development. Tonic seizures during sleep are the feature often used as the foundation for diagnosis. LGS is characterized by multiple concurrent seizure types, including tonic, atypical absence seizures, atonic, and myoclonic jerks. Non-convulsive status epilepticus, lasting days to weeks, occurs in half of patients. The etiology of LGS is heterogeneous and includes both genetic and acquired causes. LGS most commonly first manifests in children between 3 and 5 years of age, but onset can also occur at younger and older ages. It has been reported that 20-36% of children diagnosed with LGS syndrome have a history of West syndrome.
