Epilepsy is characterized by sporadic episodes that do not differ from normal when seizures do not occur; therefore, many patients wonder if they must be prevented and treated with drugs. It is important to clarify that epilepsy is a pathological phenomenon of the brain. Regardless of the type, during seizures, patients can have clear or unclear consciousness, general or partial convulsions, sometimes accompanied by psychiatric symptoms, and severe convulsions often cause cerebral hypoxia, cerebral edema, and disorders of brain metabolism. Recurrent seizures can also lead to personality changes and psychological abnormalities that can make life difficult. The role of antiepileptic drugs is precisely to control and prevent seizures. Except for patients who only have one seizure in several years and do not need to take medication, all other patients should receive timely medication under the guidance of a doctor to prevent seizures.
