Early prognosis of epilepsy. Effects of treatment in the first follow-up year

A multicenter prospective investigation was conducted in 17 teaching and general hospital in Italy to assess the efficacy of the care delivered to previously untreated patients with epilepsy. 175 cases were included and allocated to monotherapy. Only 112 cases completed the first year of follow-up. Of these, 59 (52.7%) were completely controlled and 53 (47.3%) had one or more seizure relapses. Controlied and uncontrolled patients were compared with respect to the main variables believed to influence non-responsiveness to standard therapy. The proportion of cases with relapses was significantly associated with the number of seizures reported before treatment was started. Selected seizure patterns (absences, myoclonic seizures) and prolonged disease duration were also reported more frequently among patients with recurrences. The implications of these findings are discussed with respect to drug response and prognosis of epilepsy.
