Populations are aging, and the incidence of epilepsy is increased in t
he elderly population. These demographic facts emphasize the importanc
e of understanding the use of antiepileptic drugs in older patients. H
ealthy elderly have expected alterations in renal blood flow, hepatic
volume and function, and alterations in fat-to-lean ratio of body comp
osition. All of these changes make elderly patients vulnerable to dose
-related adverse effects of the standard antiepileptic drugs. Newly de
veloped compounds without enzyme induction effects and renal routes of
excretion may be more favorable for use in elderly patients. (C) 1998
