The article presents a revised practical clinical definition of epilepsy, which was adopted by the International League Against Epilepsy (ILAE) in 2014. The new definition broadens the scope of epilepsy to include cases where a patient has a single unprovoked seizure but is at high risk for further seizures, such as after a stroke, CNS infection, or trauma. The definition also includes conditions like recurrent reflex seizures and epilepsy syndromes. Epilepsy is considered resolved if the patient has been seizure-free for 10 years and off antiseizure medications for 5 years, or if they have passed the age of an age-dependent epilepsy syndrome. The revised definition aims to better align with how epileptologists think about epilepsy and to provide more precise guidance for clinical diagnosis and treatment. It also addresses the stigma associated with epilepsy and the need for early diagnosis to prevent unnecessary risks and comorbidities.The article presents a revised practical clinical definition of epilepsy, which was adopted by the International League Against Epilepsy (ILAE) in 2014.
