Depression and anxiety improve after epilepsy surgery

13.12.2005


Depression and anxiety are common problems for people whose epilepsy cannot be controlled by medication. A new study found that depression and anxiety improve significantly after epilepsy surgery.



The study, which is published in the December 13, 2005, issue of Neurology, the scientific journal of the American Academy of Neurology, found that the rate of depression and anxiety disorders decreased by more than 50 percent up to two years after the surgery. People who no longer experienced any seizures after surgery were even more likely to be free of depression and anxiety.

"These results are important because depression and anxiety can significantly affect the quality of life," said study author Orrin Devinsky, MD, Professor of Neurology, Neurosurgery, and Psychiatry at New York University School of Medicine and Director of the NYU Comprehensive Epilepsy Center. "For people with refractory epilepsy, studies show that depression is more likely to affect their quality of life than how often they have seizures or how many drugs they have to take."


The study involved 360 people in seven U.S. epilepsy centers who were undergoing epilepsy surgery to remove the area of the brain producing the seizures. Epilepsy surgery is generally reserved for those whose seizures cannot be adequately controlled by medication. The majority of participants had surgery on the brain’s temporal lobe. The participants’ mental health and any symptoms of depression and anxiety were evaluated before surgery and at three months, one year, and two years after surgery.

Prior to the surgery, 22 percent of the participants met the criteria for a diagnosis of depression, compared to 9 percent two years after the surgery. For anxiety disorders, 18 percent met the criteria for a diagnosis before the surgery, compared to 10 percent two years after the surgery.

Of those who had no seizures following surgery, 8 percent met the criteria for depression, compared to 18 percent of those who still had some seizures after surgery. For anxiety, 8 percent of those who were seizure free had depression, compared to 15 percent of those with ongoing seizures.

Researchers aren’t sure why depression and anxiety improve after epilepsy surgery. "Removing dysfunctional areas of the brain may be critical," Devinsky said. "Whether the benefit comes from reducing or eliminating seizures or other effects is not clear. People may also be benefiting from an improved sense of self-control, less fear of seizures, higher activity levels and a lessened burden from medications."

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
