Abstract

The clinical details, specialist investigation, pharmacological treatment and outcome in 1000 consecutive patients referred to the epilepsy clinic at the Western Infirmary in Glasgow were reviewed. Data were collected by detailed proforma at initial referral and from the clinical notes at audit. 524 (52%) of the patients were 30 years of age or younger. 527 (53%) were sent to the clinic by their general practitioner with the majority of the remainder being referred by another hospital consultant. 240 (24%) came from outwith greater Glasgow. In 253 (25%) patients a possible predisposing factor was identified, usually a major head injury or alcohol abuse. Sixty (6%) patients suffered from additional mental handicap. Focal spike and wave activity was identified in 26% of electroencephalograms. One or more abnormality was found in 33% of the 356 patients who underwent computerized tomographic brain scanning. In 13 (11%) of these, a tumour was demonstrated. On referral, 65% of patients were being treated with antiepileptic drugs; 58% were on monotherapy and 42% took more than one anticonvulsant. The figure at audit was 77% treated, with a higher proportion (68%) than at referral receiving monotherapy (P < 0.005). Sedative anticonvulsants, such as phenobarbitone and primidone, were withdrawn in 29% of cases. 50% of the 519 patients, for whom seizure frequency data were available for the years before referral and audit, were seizure-free and seizure numbers had been reduced by 50% or more in a further 23%. A poorer response to treatment was associated with mental handicap (P < 0.05), birth injury (P < 0.01), and partial or secondary generalized seizures (P < 0.005).
