Lennox-Gastaut syndrome is progressive as the seizures can be difficult to control and the behavioral and cognitive impairment that is associated with Lennox-Gastaut syndrome often gets worse over time, most particularly with persistent seizures.
Lennox-Gastaut syndrome (LGS) is a severe type of epilepsy syndrome that is characterized by multiple types of seizures which include tonic, atonic, atypical absence, myoclonic and generalized tonic clonic seizures.
These types of seizures in Lennox-Gastaut syndrome are often resistant to multiple medications and the condition can also cause significant developmental and intellectual challenges.
Lennox-Gastaut syndrome is considered the most severe type of epilepsy because it involves several different types of seizures and some of which are more likely to cause injuries.
And seizures in Lennox-Gastaut syndrome can even often lead to brain damage and cause learning difficulties, developmental setbacks and loss of previously learned abilities.
Lennox-Gastaut syndrome seizures are often difficult to control with medications and multiple medications may be required, but complete control of the seizures is rare.
People with Lennox-Gastaut syndrome can live into their 50s and 60s although some are more likely to die prematurely as a result of the underlying brain disorder, seizures and injuries, aspiration, accidents, pneumonia or even Sudden Unexpected Death in Epilepsy.
