There are many different types of seizures that people with epilepsy can have, and the symptoms are not always the same. Due to the spike of activity in the brain, some people may experience rhythmic jerking movements for extended periods of time, as well as weak, tense, or rigid muscles. When most people think of seizures, they typically picture something called “epileptic spasms,” in which someone’s body flexes and extends repeatedly. Less-obvious symptoms of a seizure can also include changes in mood and emotion, goosebumps, heart-racing, or “behavior arrest,” which simply means someone stops moving. Seizures can be triggered by known stimuli or situations (such as flashing lights or sleep deprivation), and other times they happen seemingly randomly.
