摘要

OBJECTIVES—To studyprospectively long term dynamics and patterns of treatment in apopulation based cohort of patients with newly diagnosed epilepsy.
METHODS—564 patientswith definite epilepsy entered the UK National General Practice Studyof Epilepsy (NGPSE), between 1984 and 1987,and were prospectivelyfollowed up for between 11-14 years.
RESULTS—Treatment wasstarted in 433 (77%) patients. Only 15% of single seizure patientshad medication prescribed initially, although due to high seizurerecurrence, more than 70% ultimately received antiepilepticmedication. 209/564 patients (37%) were on drug therapy for epilepsyat the time of last follow up. 168/564 patients (30%) have stayedcontinuously on medication and another 41/564 patients (7%) restarteddrug therapy because of seizure recurrence, having withdrawnmedication. 98/209 (47%) of those on treatment are known to be in 5 year terminal remission. Phenytoin (29%) and carbamazepine (27%) werethe most commonly preferred first line drugs followed by valproate(15%). Less than half of treated patients with partial seizuresreceived carbamazepine as a first line drug and less than a third withgeneralised seizures were prescribed valproate as first choice drug.Nine out of 31 (29%) patients with one or more seizures a week at lastfollow up had never tried a second drug and only seven (23%) had triedfour or more drugs. 11% of all treatment changes involved a newantiepileptic drug. Treatment changes were associated with low terminalremission rates.
CONCLUSIONS—Out of30 000 patients with newly diagnosed epilepsy every year in the UnitedKingdom, about 6000 have inadequate seizure control in the long term.About a third of the patients in this group have one or more seizuresevery month. Only two thirds of these patients with frequent seizuresare likely to switch medication to try and achieve better seizurecontrol. There is probably still considerable room for improvement inprescribing practice in the United Kingdom.
