Today we will tell about the brain disorder known as epilepsy. Many people do not understand epilepsy. Medical experts are working to understand it and improve the lives of those who suffer from it. Epilepsy is a medical condition that produces seizures. A seizure happens when a sudden increase of electrical activity interferes with normal operations in the brain. Nerve cells use electrical particles to communicate with each other. Millions of electrical particles pass between nerve cells in the brain. When the brain has a sudden burst of electricity, the body experiences physical changes called epileptic seizures. Victims can shake uncontrollably for brief periods. They also can temporarily lose the ability to think clearly or communicate. New research is helping to explain how cells communicate to cause conditions like epilepsy. Douglas Fields is a researcher with America's National Institutes of Health. A few years ago, he showed that a chemical called ATP could be linked to disorders like epilepsy and chronic pain. Most seizures can last anywhere between 30 seconds and two minutes. These seizures do not cause permanent damage. However, a seizure is considered a medical emergency if it lasts more than five minutes. One in 10 adults will have a seizure during their life. Different kinds of seizures result when different parts of the brain are affected. If electrical activity increases in only one area of the brain, the person will have what doctors call a partial seizure. Many times, people may suffer a partial seizure and not know it. They might note strange feelings in an arm or leg. They also might hear noises or look straight ahead for a few minutes. |
