The medical treatment of seizure disorders is a complex process, requiring extensive interaction and cooperation between physician and patient. The physician must have an accurate diagnosis of the patient's illness and a comprehensive understanding of seizures and seizure disorders. The physician must consider specific individual characteristics of the patient, especially those that will influence the choice of medical therapy, and the interrelationship between the patient's lifestyle and the seizure disorder must be appreciated to maintain an optimal quality of life. Finally, the physician must have a thorough understanding of the pharmacology of antiepileptic drugs (AEDs) and experience with their therapeutic applications. It is important for patients to be fully involved in the treatment of their illness. Each patient should be informed about their disorder, should be involved in all therapeutic plans and strategies, and should be a responsible and active participant in treatment.
