Medline ® Abstract for Reference 43

BACKGROUND: Old age is the most common time in life to develop epilepsy. Despite this, there are few published data exploring pharmacological outcomes in this population.

METHODS: We analyzed outcomes in 117 older patients (median age, 73; range, 65-92) for whom localization-related epilepsy was newly diagnosed and treatment begun at a single center over a 20-year period.

RESULTS: Seventy-three (62%) patients became seizure-free for at least 12 months on their first AED, with 30 (26%) failing to respond and 14 (12%) not tolerating the treatment. Following pharmacological manipulation, 93 (79%) patients attained remission, 87 (93%) on monotherapy and 6 (7%) on duotherapy. No individual AED was more likely to confer seizure freedom than any other. Patients attaining remission were more likely to have had fewer pretreatment seizures (P=0.0078) than those who did not obtain full seizure control.

CONCLUSION: The prognosis in epilepsy may be better in older than younger people, perhaps reflecting lower lesional epileptogenicity and genetic predisposition.
