=====Focal seizure=====
Focal [[seizure]]s can arise from coordinated activity across large-scale epileptic networks and propagate to regions that are not functionally altered but are recruited by epileptiform discharges.
----

[[Focal seizure]] may evolve to bilateral tonic-clonic (previously called secondary-generalized). Atonic, clonic, tonic, [[myoclonic seizure]]s and [[epileptic spasm]]s can be either of focal or generalized onset. Unclassified type of seizure was introduced. New types of seizures (absence with [[eyelid myoclonia]], myoclonic absence, myoclonic atonic and clonic-tonic-clonic seizures) were added
