title: Assessment of Seizure Severity with Adjunctive Lamotrigine Therapy: Results from a U.S. Observational Study.
abstract: THE ADJUNCTIVE LAMICTAL (LAMOTRIGINE) IN EPILEPSY: Response to Treatment (ALERT) study was an observational study designed to assess the safety of lamotrigine in patients with refractory partial seizures when used in a general practice setting. We measured the impact of adjunctive lamotrigine therapy for 16 weeks on the severity of seizures using the Liverpool Seizure Severity Scale (LSSS). This questionnaire was scored using a revised scoring procedure that assesses the impact of treatment on the patients "most severe seizure." Data from the LSSS were also compared with physician-rated changes of seizure severity. Patients who completed 16 weeks of lamotrigine treatment showed a significant reduction in LSSS scores when compared with patients who discontinued lamotrigine (change scores: patient's taking lamotrigine at Week 16, 9.2 +/- 23.4; patients who discontinued lamotrigine by Week 16, 0.8 +/- 23.4, P < 0.05). These findings were supported by significant reductions in physician ratings of seizure severity in patients who completed 16 weeks of lamotrigine therapy. Seizure severity is an important outcome in the study of antiepileptic medication. Data from this observational study suggest that lamotrigine is effective in reducing seizure severity when used as an adjunctive therapy in patients with refractory partial seizures.
