Epilepsy surgery: Careful candidate selection produces comparable results

April 01, 2003

HONOLULU, HI - In developing countries, where epilepsy surgery facilities, technology and expertise are limited, researchers have sought to identify factors most predictive of excellent results among candidates for epilepsy surgery. Findings from research conducted in Kerala, India, are being presented at the American Academy of Neurology Annual Meeting in Honolulu, March 29-April 5, 2003.

Among treatment options for epilepsy patients with intractable, temporal lobe seizures, anterior temporal lobectomy (ATL) surgery has yielded nearly a 60 percent success rate in eliminating seizures, according to previously published research (JAMA, June 2001). Medication therapy alone was shown to decrease the frequency and/or intensity of seizures in less than 10 percent of these patients.

"By carefully selecting ideal candidates for ATL using an actuarial approach and the Seizure Scoring System, we found that epilepsy surgery programs in developing countries with limited facilities can produce results comparable to those from developed countries," concluded study author Kurupath Radhakrishnan, MD, professor and chair, Department of Neurology, and Head, Epilepsy Program, Sree Chitra Tirunal Institute for Medical Sciences & Technology, Trivandrum, Kerala, India.

Given the obvious benefits of surgery (after medication has been proven ineffective), researchers from R. Madhvan Nayar Center for Comprehensive Epilepsy Care, Sree Chitra Tirunal Institute for Medical Sciences and Technology, Trivandrum, Kerala, South India, audited their epilepsy surgery program to identify factors most predictive of successful outcomes. They studied 243 consecutive patients, selected by noninvasive evaluation, who underwent ATL and had at least two years of post-surgery follow-up.

Epileptic seizures can probably not be predicted by changes in brain wave patterns that were previously assumed to be characteristic precursors.

Predicting epileptic seizures might be more difficult than previously thought
By studying the brain dynamics of 28 subjects with epilepsy, scientists demonstrated there is no evidence for a previously suspected warning sign for seizures known as 'critical slowing down,' which refers to characteristic changes in the behavior of a complex system that approaches a theoretical tipping point; when this point is exceeded, there can be impactful and devastating changes.

Researchers identified a gene in fruit flies that helps prevent the hyperexcitability of specific neurons that trigger seizures.

Research from Washington University in St. Louis finds that mutations of a gene implicated in long QT syndrome in humans may trigger seizures because of their direct effects on certain classes of neurons in the brain -- independent from what the genetic mutations do to heart function.
