Epilepsy outcomes in elderly treated with topiramate

Abstract

OBJECTIVES: To explore effectiveness, tolerability and quality of life in elderly patients with epilepsy treated with topiramate. METHODS: One year, open-label, flexible-dosing clinical trial. RESULTS: One hundred and seven patients (mean age 69 years, 53% men) were studied during 273 +/- 141 days. The average final dose in monotherapy was 98 mg/day vs 153 mg/day in adjunctive treatment. Mean monthly cumulative seizure frequency decreased from 3.7 +/- 15 to 1.6 +/- 7.7 (n = 101, P < 0.0001), 78% of patients with seizures at baseline (n = 102) achieved at least 50% reduction in seizure frequency, 44% were seizure-free throughout the trial. Total scores on the quality of life in epilepsy inventory (QOLIE-31) improved from 57 +/- 17 to 68 +/- 18 (n = 64, P < 0.0001). The most frequently reported adverse events included convulsions, dizziness and tiredness. CONCLUSIONS: Elderly patients treated with topiramate showed marked reductions in seizures, good tolerability and significant improvements in several aspects of quality of life.
