Early treatment and prognosis of epilepsy.

Community-based studies and our own prospective hospital-based studies suggest that the prognosis for control of epilepsy is more favorable than previously reported. Approximately three quarters of newly diagnosed patients can enter prolonged remission on currently available medication. The first 2 years of treatment are crucial in determining the subsequent course of epilepsy. The longer seizures continue, the less likely they are to be controlled. Factors that contribute to the evolution of chronic epilepsy are the presence of brain lesions, neuropsychiatric handicaps, and poor compliance. Early effective treatment may also be important in preventing the evolution of chronic epilepsy. Recent studies have not revealed any significant differences in efficacy between the major antiepileptic drugs, and the choice of drug will therefore be influenced by costs and side effects, especially cognitive and behavioral effects. The majority of patients with a single unprovoked tonic-clonic seizure go on to develop epilepsy. Studies are required to evaluate the need for and outcome of therapy in such patients. Information about the natural history of untreated epilepsy, and also the possible influence of drug therapy on the prospects for spontaneous remission, is lacking.
