ICD-10 code G40. 814 for Lennox-Gastaut syndrome, intractable, without status epilepticus is a medical classification as listed by WHO under the range - Diseases of the nervous system .
Lennox-Gastaut syndrome (LGS) is a severe form of epilepsy that typically becomes apparent during infancy or early childhood. Affected children experience several different types of seizures most commonly atonic, tonic and atypical absence seizures.
Causes. Lennox-Gastaut syndrome can have many different causes. The disorder likely has a genetic component, although the specific genetic factors are not well understood. Most cases of Lennox-Gastaut syndrome are caused by an existing neurological abnormality.
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.
Lennox-Gastaut syndrome (LGS) is a type of epilepsy. Patients with LGS experience many different types of seizures including: Tonic - stiffening of the body. Atonic - temporary loss of muscle tone and consciousness, causing the patient to fall. Atypical absence - staring episodes.
Lennox-Gastaut syndrome is a progressive epilepsy syndrome that causes tonic and atypical absence seizures and intellectual disability. It is difficult to treat, although some newer treatments are being investigated.

Lennox-Gastaut syndrome (LGS) is a severe epileptic encephalopathy with childhood onset that usually continues through adolescence and into adulthood. In the long term, patients with this condition still have intractable seizures, intellectual disability, behavioral problems, and physical comorbidities.
Although onset after age 8 is rare, LGS has been diagnosed into adolescence and adulthood [4], [5], [6]. The vast majority of children who develop LGS will continue to exhibit at least some of its features into adulthood.
Tonic-clonic seizures. Tonic-clonic seizures, previously known as grand mal seizures, are the most dramatic type of epileptic seizure. They can cause an abrupt loss of consciousness and body stiffening, twitching and shaking. They sometimes cause loss of bladder control or biting your tongue.
