Diagnostic and therapeutic reevaluation of patients with intractable epilepsy

Intensive monitoring techniques were used to improve seizure diagnosis and control in 23 patients with intractable epilepsy: (1) Video recording of clinical seizures and the ictal EEG, (2) long-term telemetered EEG recordings, and (3) frequent determination of plasma antiepileptic drug concentrations. Patients were monitored in the hospital for an average of 8 weeks and after discharge were followed for an average of 8 months. At follow-up, 70 percent of the patients continued to have improved seizure control as compared with baseline studies, 83 percent had decreased toxicity, and about half had made gains in social adjustment. Use of the techniques described can make a significant contribution to patients previously considered intractable to therapy.
