Summary

Approximately a third of patients with epilepsy continue to have seizures despite multiple trials of antiepileptic drugs. Refractory epilepsy can have significant adverse effects on the physical, psychological, cognitive, social, educational, and vocational well-being of the individual and thus represent a major public health concern. Clinicians caring for individuals with refractory seizures should regularly re-evaluate the patients to be certain they are treating epileptic seizures rather than nonepileptic behaviors and they are treating the correct seizure type and syndrome with the correct antiepileptic drug. Assessing medication compliance and precipitating factors triggering seizures is important in determining whether the patient is truly medically intractable. There should be an ongoing effort to determine the correct etiology of the epilepsy as treating the underlying cause of the seizures may be far more effective than concentrating solely on treatment of the seizures. Identifying seizure triggers and encouraging compliance may dramatically improve seizure control. Finally, patients who have refractory epilepsy despite the best efforts of the clinician should be referred to tertiary epilepsy centers where the patient can undergo a comprehensive evaluation for etiology of the epilepsy and be assessed for possible epilepsy surgery or experimental therapeutics.
