Seizures associated with LGS
The onset of Lennox-Gastaut syndrome (LGS) does not begin with a specific type of seizure. For young children when there is no known cause, LGS usually begins with a "drop attack" followed by other seizures.1 The names and specific signs of the different seizure types are listed below. Keep in mind that as your child grows from childhood to adulthood, the seizures he or she experiences may change.

Focal or generalized atonic (formerly atonic)2

A period of jerking movements.4
Focal or generalized myoclonic (formerly myoclonic)2
Partial, or focal onset
Generalized or unknown onset tonic clonic (formerly tonic clonic)2
