In 1981, the [[International League Against Epilepsy]] (ILAE) classified epileptic [[seizure]]s as [[Focal seizures|partial seizures]] ([[simple partial seizure]]s, [[complex partial seizure]]s, and [[partial seizures]] evolving to secondarily [[generalized seizures]]), [[Generalised epilepsy|generalized seizures]] ([[absence seizure]]s, [[myoclonic seizure]]s, [[clonic seizure]]s, [[Tonic |tonic]] seizures, [[tonic-clonic seizure]]s (grand mal), and [[atonic seizure]]s), and unclassified epileptic seizures.
In 2017, the [[International League Against Epilepsy]] (ILAE) classified [[seizure]] by its onsets as focal (aware/impaired awareness, motor, nonmotor, focal to tonic-clonic seizures), generalized (motor, nonmotor), and unknown (motor, nonmotor, and unclassified).

Overview

In 2017, the International League Against Epilepsy (ILAE) classified seizure by its onsets as focal (aware/impaired awareness, motor, nonmotor, focal to tonic-clonic seizures), generalized (motor, nonmotor), and unknown (motor, nonmotor, and unclassified). In 1981, the International League Against Epilepsy (ILAE) classified epileptic seizures as partial seizures (simple partial seizures, complex partial seizures, and partial seizures evolving to secondarily generalized seizures), generalized seizures (absence seizures, myoclonic seizures, clonic seizures, tonic seizures, tonic-clonic seizures (grand mal), and atonic seizures), and unclassified epileptic seizures.

Classification

In 2017, the International League Against Epilepsy (ILAE) classified seizures by their onsets as:[1][2]

In 1981, the International League Against Epilepsy (ILAE) classified epileptic seizures as:[2][3]
