Juvenile idiopathic epilepsy (JIE) is a neurological disorder which resembles benign-familial neonatal convulsion (BFNC) syndrome in humans. The disorder is characterized by sporadic onset of seizures which generally disappear when the foal is between 1–2 years of age. Between episodes the foal appears normal, although there is the risk of an injury during a seizure, such as head trauma, which can cause complications.
