Generalized tonic-clonic seizures in patients with complex-partial seizures: natural history and prognostic relevance.

Abstract:

:Clinical course and long-term seizure prognosis were studied in 155 patients with complex-partial seizures during a follow-up of 10.1 +/- 1 (SD) years. In 79% of the patients generalized tonic-clonic seizures were recorded, mostly within the first 3 years of epilepsy but occurring as late as 20 years after the onset of epilepsy. Seizure control was defined as complete absence of all seizures, including auras, for a minimum of 2 years. Seizure control occurred in 20 of 32 patients (63%) with complex-partial seizures only and in 76 of 123 patients (62%) with complex-partial seizures and generalized tonic-clonic seizures. The onset of the epilepsy with generalized tonic-clonic seizures or complex-partial seizures did not influence the therapeutic outcome despite differences in their natural history. A family history of epilepsy and other generalized seizures (e.g., absence) were more frequent in patients with generalized tonic-clonic seizures at the onset of epilepsy. Seizure control was significantly lower (44%) in patients with a history of a maximum frequency of one or more generalized tonic-clonic seizures per month when compared to patients (79%) with a total of less than six generalized tonic-clonic seizures (p less than 0.05). The frequency of generalized tonic-clonic seizures is of predictive value for the seizure prognosis of patients with complex-partial seizures.
