A seizure is a sudden change in behavior caused by electrical hypersynchronization of neuronal networks in the cerebral cortex (gray matter). What does this mean? The electrical activity of the brain gets “messed up” randomly and disrupts normal brain function.
What is the Presentation of a seizure? Seizures can appear as abnormal sensations, altered awareness (e.g., confusion spells), convulsions – both generalized (e.g., full body shaking tonic-clonic movements) and focal involuntary movements (e.g., twitching of lip, or an arm). Most seizures are relatively brief, lasting a few seconds to a few minutes. Most people who have a seizure disorder behave & look normal in between seizures.
