Outcomes from a nurse-led clinic for adolescents with epilepsy

PURPOSE Epilepsy is the commonest serious neurological condition to affect adolescents. We established a nurse-led clinic for young people with suspected or diagnosed epilepsy. Outcomes in all patients referred during the first 4 years after its inception are reported. METHODS A total of 301 adolescents were seen at the clinic during 1996-1999. Epilepsy was excluded in 135 (45%), including 5 receiving antiepileptic drug (AED) therapy. A single seizure occurred in 22 (7%) others. Seventy-six patients (25%) had treated epilepsy and 68 (23%) were newly diagnosed. RESULTS More than 1 year's seizure freedom was achieved by 53% of patients, 76% with one AED, 16% with two and 3% with three. Four (5%) patients remained seizure free off medication. Sixteen (11%) were lost to follow-up. Outcome was better (P<0.05) for newly diagnosed (59% seizure free) than for treated (47% seizure free) epilepsy and for idiopathic generalised (60% seizure free) than for partial (46% seizure free) seizures (P<0.02). Magnetic resonance imaging of brain was obtained in 63 (85%) patients with localisation-related epilepsy. Findings were abnormal in 43%, including nine with cortical dysplasia, eight with mesial temporal sclerosis and two with gliomas. CONCLUSIONS Epilepsy can be difficult to diagnose in adolescents. Outcomes were surprisingly poor suggesting the need for improved services for this patient population.
