Developmental epilepsy is a symptomatic form of the disorder in which seizures occur due to congenital or acquired problems in brain function, such as structural abnormalities or neurodegenerative diseases. This condition is often accompanied by delays in psychomotor or cognitive development, including attention, memory, and speech impairments. The most common cause in children is congenital malformations or brain lesions, which can lead to severe forms such as West syndrome.
