Brain Cooling to Treat Epilepsy

Chronic focal brain cooling suppresses seizures during wakefulness and achieves the effect without significantly affecting brain function. These findings were reported by neuroscientists from Japan's Yamaguchi University during the 66th annual scientific meeting of the American Epilepsy Society (AES).

Their research, and that of others in the field, provides critical evidence that this approach to seizure control has reached a stage where testing in humans will soon be possible.

Fits or convulsions or Epilepsy is characterized by recurrent, involuntary seizures and is described as a chronic neurological disorder

Focal brain cooling is well established as an effective method for suppressing seizures. But the technology for creating a practical device with potential clinical application has only recently become available and tested in rodents. More evidence from large animals and humans is needed prior to testing in clinical trials for drug-resistant epilepsy.

The Yamaguchi researchers implanted two feline and two non-human primates with a titanium cooling plate, or heat exchanger. The brain cooling device was placed in contact with the brain surface over cortex areas responsible for movement and sensation. Seizures were then induced in the motor cortex. Brain wave recordings to assess seizure activity and temperature recordings were performed under wakefulness. (Abstract #3.056)

According to Masami Fujii, M.D.,Ph.D., and Takao Inoue, Ph.D., and Michiyasu Suzuki, M.D., Ph.D., who presented the report, seizure discharges were significantly suppressed at 15ËšC (59ËšF).

Neurocysticercosis or Cysticercosis of brain is the most common cause of epilepsy and the most common parasitic infection of the brain. Neurocysticercosis is more common in the developing countries.

"The results of our study suggest that focal brain cooling has a strong effect to suppress the epileptiform seizures under the awake condition," Dr. Fujii said. "Moreover, implantation of the device for at least five months did not result in detrimental changes in brain tissue subjected to cooling compared to tissue from a similar site in the opposing hemisphere."

About the American Epilepsy Society
The American Epilepsy Society, based in West Hartford, CT, seeks to advance and improve the treatment of epilepsy through the promotion of research and education for healthcare professionals. Society membership includes epileptologists and other medical and allied healthcare professionals, and scientists concerned with the care of people who have seizures and epilepsy.

Convulsions / Seizures / Fits - Symptom Evaluation
Seizure or a convulsion is a result of abnormal electrical activity in the brain. If there are two or more unprovoked seizures at an interval of at least 24 hours, it is referred to as epilepsy.

Epilepsy and Slides
Epilepsy is a medical condition where the brain cells fire abnormal electrical signals that physically manifests as a ‘Seizure’. There should be two or more seizures before the term epilepsy should be used.
