LGS is a type of epilepsy which usually develops between 1 and 8 years of age. It is characterised by multiple seizure types, developmental delay and behavioural issues. Tonic and atonic seizures are most commonly experienced, and often difficult to control.
Children with Lennox-Gastaut syndrome may also develop cognitive dysfunction, delays in reaching developmental milestones and behavioural problems. Lennox-Gastaut syndrome can be caused by a variety of underlying conditions, but in some cases no cause can be identified.
