How often seizures occur varies from person to person. Some patients with aphasic seizures can have several, dozens, or even hundreds of seizures per day, and some patients can have seizures for days, weeks, months, or even years. There are commonalities when it comes to seizures, mainly seizure, transient, repetitive and stereotyped. Seizures rarely last longer than five minutes, and if they last longer than 30 minutes or are frequent for a short period of time, they are called persistent status epilepticus. Seizures also often have individuality, meaning that different types of epilepsy each have characteristics that are the main basis for distinguishing one type of epilepsy from another. Epilepsy is not routinely treated with antiepileptic drugs if there is one seizure, and routinely treated with antiepileptic drugs if there are more than two seizures.
