- Doose’s syndrome
- Gastaut's syndrome II
- Lennox’ encephalopathy
- Lennox’ syndrome
- Lennox’ variant
A common epileptic syndrome which usually commences before the age of 6 with myoclonic seizures by day and tonic seizures at night, with atypical absences, head nodding, and drop attacks particularly prominent. Unconsciousness, epigastric, pharyngeal, or abdominal aura, a sensation of fear, and sucking movements are symptoms. Cerebral oedema and injuries are the suspected causes. It often has a poor prognosis with progressive mental deterioration. Lennox-Gastaut seizures are so powerful and occur so frequently – as often as 200 times an hour – that mental retardation is generally unavoidable.
Doose's syndrome (when strong genetic basis) is entered as a separate entity.
