SEATTLE—Epilepsy is associated with an increase in mortality among elderly veterans, a rate that is
higher for those who have a new diagnosis of epilepsy
compared with a pre-existing diagnosis, researchers
reported at the 68th Annual Meeting of the American
Epilepsy Society.
Perry Foreman, MD, PhD, and colleagues used VA
administrative data to identify veterans age 66 and older who received VA care in fiscal years 2005 and 2006.
The veterans were classified as the epilepsy cohort or
the nonepilepsy cohort based on a previously vali-
dated algorithm. The primary outcome measure was
mortality within the epilepsy and nonepilepsy cohort
groups, which was compared with a no-epilepsy co-
hort using the VA minivital status file. In addition, the
investigators identified covariates that included patient
demographics (age, gender, and race), disease burden,
and comorbid conditions.
In a previous study of elderly veterans with a
new diagnosis of epilepsy, the investigators had
found “an extremely high absolute mortality of 12%
at one year, and 32.9% within three years,” according to Dr. Foreman, an epileptologist at the Epilepsy Center, LifeBridge Health Brain & Spine Institute
in Baltimore.
In their current study, for 2006, Dr. Foreman and
colleagues identified 35,611 veterans with chronic
epilepsy and 1,412 veterans with a new diagnosis
of epilepsy. In the chronic epilepsy veteran group,
2,468 deaths ( 6.9%) occurred, and in the new
