BACKGROUND Diagnostic work-up and treatment of patients who have developed epilepsy after the age of 65 can both be difficult. Epilepsy is one of the most common neurological conditions in the elderly, and the incidence of de novo geriatric epilepsy is rising. The aim of this review is to provide guidance on the management of epilepsy in this patient group.
METHOD The review is based on a discretionary selection of original articles and reviews found in PubMed using the search term combination 'epilepsy' and 'elderly', and the authors' personal experience.
RESULTS The seizures, which are most commonly of the focal type, are not infrequently overlooked or misdiagnosed. Cerebrovascular disease is the underlying cause of about half of the cases. When selecting an anticonvulsant, it is important to take age-related physiological changes and comorbidities into consideration. Because elderly patients have a narrower therapeutic window than younger persons and greater susceptibility to cognitive and other side effects, a low starting dose and slower dose titration are particularly important.
INTERPRETATION The results of studies of young epilepsy patients cannot be extrapolated to apply to elderly patients. More studies directly targeting this patient population are therefore needed. As a general rule, we do not recommend starting on enzyme-inducing drugs such as phenytoin, phenobarbital and carbamazepine, partly because of their high interaction potential.
