Epilepsy, also called seizure disorder, is a group of conditions centering around a tendency to have seizures. A seizure is an unusual outburst of electrical activity in the brain.
Your brain runs and communicates with electricity. Neurons, or nerve cells, speak to each other and to the rest of the body with electrical signals. During a seizure, there is a huge increase in the electrical activity of these cells. This increase can cause a person to lose consciousness, to experience sensations that aren’t real, or to lose control of their muscles and movement. There are lots of different types of seizures, and they affect people in different ways.
Seizures are usually short, and they’re not generally medical emergencies in a person with epilepsy. There are simple ways to help a person having a seizure. If you know someone with epilepsy, keep these in mind.
