20 years without recurrence of epilepsy can usually be considered as epilepsy is well controlled and in a state of clinical cure, it is recommended to review regularly and pay attention to the development of good healthy living habits. Generally speaking, it is clinically considered to be cured when there is no recurrence of seizures within 3 years after stopping medication. Most people can achieve good symptom control and no more seizures after systematic and regular antiepileptic treatment. However, some patients with refractory epilepsy or specific types of epilepsy may still have recurrence of seizures, and studies have shown that 15% of patients who are clinically cured still have seizure recurrence within 10 years. Increasing or decreasing medications, as well as discontinuing them, should be done under the supervision of a physician. If epilepsy has not recurred for more than 20 years, it can usually be considered completely controlled and clinically cured, and regular medical checkups should be insisted on. If there is any change in the condition, consult a doctor in a timely manner for treatment under the guidance of a physician.
