The International League Against Epilepsy (ILAE) and the International Bureau for Epilepsy (IBE) have come to consensus definitions for the terms epileptic seizure and epilepsy, An epileptic seizure is a transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain but epilepsy is a disorder of the brain characterized by an enduring predisposition to generate epileptic seizures and by the neurobiologic, cognitive, psychological, and social consequences of this condition. [2] Approximately 4-10% of children experience at least one seizure (febrile or a febrile) in the 1st 16 yr of life, the cumulative lifetime incidence of epilepsy is 3%, and more than half of the cases start in childhood. [1] Seizure disorder is a general term that is usually used to include any of several disorders, including epilepsy, febrile seizures, and possibly single seizures and symptomatic seizures secondary to metabolic, infectious, or other etiologies (e.g., hypocalcaemia,meningitis).[1] In the International League Against Epilepsy (ILAE) classification of etiology of epilepsy, idiopathic epilepsy which occur without organic cause, and symptomatic epilepsy that associated with underlying brain disorder that may or may not be genetic .[2] The definition of epilepsy requires the occurrence of 2 or more unprovoked seizures occur in a time frame of longer than 24 hr .[3] There are 2 main types of seizures: generalized and focal, focal seizures are those arising within networks of a single cerebral hemisphere and may remain localized or subsequently become more widely distributed.[4] Generalized seizures rapidly affect both hemispheres as well as both sides of the body even when caused by a "focal" lesion.[4] Focal (formerly known as partial) seizures are subdivided into simple partial seizures which is refers to focal seizures with no alteration in consciousness and complex partial seizures associated with altered awareness of the surroundings.[4] Generalized seizures are further subdivided to tonic (sustained contraction), clonic (rhythmic contractions), myoclonic (rapid shock-like contractions, usually<50 msec in duration, that may be isolated or may repeat but usually are not rhythmic), atonic, or astatic (cause avery momentary loss of tone with sudden fall ) Absence seizures (generalized seizures consisting of staring, unresponsiveness, and eye flutter lasting usually for few seconds).[4]
