The International League Against Epilepsy (ILAE) define an<unk>  seizure as "a transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain." Convulsive or<unk> -convulsive seizures can occur in someone who does not have epilepsy – as a consequence of head injury, drug overdose, toxins, eclampsia or febrile convulsions. A provoked (or an un-provoked, or an idiopathic) seizure must generally occur twice before a person is diagnosed with epilepsy. When used on its own, the term seizure usually refers to an<unk>  seizure. The lay use of this word can also include sudden attacks of illness, loss of control, spasm or stroke. Where the physician is uncertain as to the diagnosis, the medical term paroxysmal event and the lay terms spells, funny turns or attacks may be used.
