A seizure is a sudden change in behavior characterized by changes in sensory perception or motor activity due to brain abnormal electrical discharge. A seizure may be provoked (for example, by trauma or fever) or unprovoked. Epilepsy is the occurrence of two or more unprovoked seizures. Epilepsy is a symptom, not a single disease entity, and has many causes. The classification of the International League Against Epilepsy distinguishes two dichotomies in epilepsy syndromes: partial or focal onset (“localization-related”) versus generalized onset, and idiopathic (genetic) versus symptomatic. Specific syndromes can be identified in each group. Seizures of partial onset may secondarily generalize. |
