===Seizure Types===
''Classification is based on the international classification from 1981<ref>Proposal for revised clinical and electroencephalographic classification of epileptic seizures. From the Commission on Classification and Terminology of the International League Against Epilepsy. Epilepsia 1981; 22:489.</ref>; More recent terms suggested by the ILAE (International League Against Epilepsy) task Force.<ref>Epilepsia 2015; 56:1515-1523.</ref>''
====Focal seizures====
''(Older term: partial seizures)''
*'''Without impairment in consciousness'''– (AKA Simple partial seizures) 
**With motor signs (ex. facial twiching or rhythmic ipsilateral extremity movements)
**With sensory symptoms (ex. tingling or pereiving a certain smell)
**With autonomic symptoms or signs (ex. tachycardia or diaphoresis)
**With psychic symptoms (including aura, ex. sense of déjà-vu)
*'''With impairment in consciousness''' - (AKA Complex Partial Seizures--Older terms: temporal lobe or psychomotor seizures)
**Simple partial onset, followed by impairment of consciousness
**With impairment of consciousness at onset
**These seizures may be accompanied by automatism (such as lip smacking and chewing, hand wringing, patting and rubbing)
*'''Focal seizures''' evolving to secondarily generalized seizures
**Simple partial seizures evolving to generalized seizures
**Complex partial seizures evolving to generalized seizures
**Simple partial seizures evolving to complex partial seizures evolving to generalized seizures

====Generalized seizures====
*'''Absence seizures''' (Older term: petit mal; brief dissociative states without postural changes)
**Typical absence seizures
**Atypical absence seizures (last longer and often include more motor involvement)
*'''Myoclonic seizure''' (violent muscle contractions)
*'''Clonic seizures''' (rhythmic jerking)
*'''Tonic seizures''' (stiffening)
*'''Tonic–clonic seizures''' (Older term: grand mal)
*'''Atonic seizures''' (loss of muscle tone -> drop attacks)

*Sudden Unexpected Death in Epilepsy
*Generalized tonic-clonic seizure is the major risk factor for SUDEP, and seizure freedom is strongly associated with decreased risk
**Annual incidence of SUDEP in children is 1 in 4500
**Incidence in adults is 1 in 1000
