Few Operations for Epilepsy despite Their Safety and Efficacy

26.11.2014

A study at Sahlgrenska Academy has found that epilepsy surgery is a safe, effective and low-risk procedure. Nevertheless, few Swedes have the operation, and those who are interested may have to wait a long time for presurgical counseling.

The study at Sahlgrenska Academy, University of Gothenburg, was based on the Swedish National Epilepsy Surgery Register, which includes all cases since 1990. The researchers reviewed data for the 865 patients who were operated on at Sweden's six epilepsy surgery clinics from 1996 to 2010.

University of Gothenburg

The purpose of surgery is to enable a person with severe epilepsy to be free of seizures or to reduce their frequency to the point that (s)he can enjoy better quality of life.

Downward trend
Only 3% (25) of the patients suffered lasting complications. A comparison with a previous study showed that the complication rate had trended downward.

The Gothenburg study is one of many that have demonstrated the safety and efficacy of epilepsy surgery. A long-term follow-up study in 2013 based on the Swedish National Epilepsy Surgery Register found that more than 60% of adults were free of seizures 5-10 years after surgery.

20 year waiting line
Despite the encouraging data, only 50-60 procedures are performed in Sweden every year. Studies show that it takes an average of 20 years for a patient with treatment-resistant epilepsy to be referred for presurgical counseling.

"One possible reason that it takes so long is that doctors may erroneously believe that surgery is a high-risk procedure," says Johan Bjellvi, a researcher at Sahlgrenska Academy. "Our study has made an important contribution by demonstrating that the risk of complications is very low."

Another problem is that many patients do not even know that surgery is an option.

Raise awarness
The Gothenburg epilepsy surgery team is participating in an EU project to raise awareness and increase the availability of these procedures throughout Europe. One goal is to develop a new classification system for complications of epilepsy surgery.

"If we are going to further minimize the risk of operating, the potential adverse effects must be described in a uniform manner," Dr. Bjellvi says. "The EU project is designing a website for use by both doctors and patients in 17 countries."

The article Complications of Epilepsy Surgery in Sweden 1996-2010: a Prospective, Population-based Study was published online by the Journal of Neurosurgery in October.

EPILEPSY FACTS
Epilepsy manifests as seizures, with or without causing convulsions or affecting consciousness. Seizures are due to transient disturbances of the brain's neural electrical impulses. The cause may be temporary or permanent brain damage but cannot always be determined. Approximately 1% of Swedes are predisposed to experience recurring epileptic seizures. Both drugs and surgical methods are available to relieve the symptoms.

The purpose of surgery is to enable the patient to be free of seizures, to minimize their frequency or to reduce their severity by preventing involvement of larger areas of the brain. Many different procedures are available. Anterior temporal lobectomy is the most common. The purpose of certain other procedures is to limit the diffusion pathways of epileptic activity.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
