Understanding lennox gastaut syndrome

Lennox-Gastaut syndrome (LGS) is a childhood-onset epilepsy syndrome, not a single seizure type. The ILAE Task Force on Nosology and Definitions characterises it by "multiple seizure types that are drug resistant (in particular tonic seizures in sleep), cognitive and behavioral impairments, and diffuse slow spike-wave and generalized paroxysmal fast activity on EEG." Two things people get wrong. First, seizures alone do not make the diagnosis: StatPearls (NCBI Bookshelf) states LGS "is defined by a triad of multiple seizure types, characteristic EEG findings, and intellectual disabilities," and the diagnosis "requires an interictal EEG that reveals a generalized slow spike-wave pattern, with a frequency of 2.5 Hz or less." Second, the falls families describe as "drop attacks" are seizures: MedlinePlus (NLM) describes atonic seizures as caused by a sudden loss of muscle tone, and says tonic and atonic seizures "can cause sudden falls that can result in serious or life-threatening injuries," with tonic seizures typically occurring during sleep. Timing matters for recognition — StatPearls reports seizures "typically begin in early childhood, usually before the age of 8, with a peak onset between the ages of 3 and 5," and that LGS accounts for 2% to 5% of childhood epilepsies. A search for a cause often comes up empty: StatPearls notes that although many cases are linked to genetic mutations or cortical malformations, "up to 40% have no identifiable cause." This is general information, not medical advice; diagnosis and treatment decisions belong with a neurologist who knows the person.

First-line treatment

The ILAE describes the seizures of LGS as drug resistant, so care aims at reducing them — especially the falls — rather than curing them. StatPearls (NCBI Bookshelf) reports that "Valproate, often used in combination with lamotrigine or clobazam, is considered a first-line therapy," with rufinamide, topiramate, felbamate and cannabidiol oral solution among the approved treatments, and advises that clinicians "should limit medication regimens to no more than 2 drugs." The counterintuitive part: several ordinary seizure drugs are deliberately avoided — StatPearls lists phenytoin, carbamazepine, oxcarbazepine, gabapentin, lacosamide and phenobarbital as medications that "are not used in LGS as they can exacerbate certain seizure types associated with the condition." FDA labeling for EPIDIOLEX (cannabidiol) states it "is indicated for the treatment of seizures associated with Lennox-Gastaut syndrome (LGS), Dravet syndrome (DS), or tuberous sclerosis complex (TSC) in patients 1 year of age and older." Non-drug options include the ketogenic diet, vagus nerve stimulation and corpus callosotomy.
