Seizure disorders in the elderly

Abstract

Seizure disorders become increasingly common after the age of 60 years and can have a significant impact on functional status. The goal of antiepileptic drug therapy is to control seizures but preserve quality of life. If possible, seizure control should be achieved with one agent given in the lowest effective dosage. Clinical response, rather than drug levels, should guide dosage changes. All antiepileptic drugs can cause dose-dependent sedation and cognitive impairment. Although the newer agents may have theoretical advantages over standard antiepileptic agents, higher cost may limit their use. Drugs for first-line monotherapy of seizures in elderly patients include carbamazepine, valproic acid, oxcarbazepine, gabapentin, and lamotrigine.
