LENNOX GASTAUT SYNDROME

Mandatory seizures

They may be predominantly truncal (with brief vocalization due to involvement of abdominal musculature) or extend to involve proximal and distal muscles (with arms elevating and flexing and legs either flexing or extending). There may be autonomic features in association. They can occur in a series. Tonic status epilepticus may occur.
