Lennox-Gastaut syndrome is a severe form of epilepsy that typically begins in childhood. It is characterized by multiple types of seizures, including atonic, tonic, and atypical absence seizures. Children with this syndrome often experience developmental delays and cognitive challenges, making it a complex condition to manage. The exact cause of Lennox-Gastaut syndrome can vary, with some cases linked to brain injuries, genetic factors, or other underlying neurological disorders. Treatment usually involves a combination of medications, dietary changes, and sometimes surgical options to help control seizures and improve quality of life for affected individuals.
