Postoperative antiseizure medication: does it improve the chance of becoming seizure-free?

In patients who fail epilepsy surgery, postoperative use of antiseizure medication (ASM) does not affect the probability of becoming seizure free, researchers have reported.

In practice, some patients who fail epilepsy surgery eventually become seizure-free. However, it has not been established whether the use of postoperative ASM affects seizure outcomes after failed epilepsy surgery.

The researchers retrospectively reviewed outcomes in 215 patients undergoing epilepsy surgery at the University of Washington Regional Epilepsy Center in Seattle, Washington, USA, between 2007 and 2017.
