Lennox-Gastaut syndrome

Also known as: LGS
Lennox-Gastaut syndrome (LGS) is a rare disorder that typically becomes apparent during infancy or early childhood. The disorder is characterized by frequent episodes of uncontrolled electrical disturbances in the brain (seizures) and, in many cases, abnormal delays in the acquisition of skills that require the coordination of mental and muscular activity (psychomotor retardation). Individuals with the disorder may experience several different types of seizures. Lennox-Gastaut syndrome may be due to or occur in association with a number of different underlying disorders or conditions.
