A primary characteristic of a seizure is a burst of uncontrolled electrical activity in the brain. This abnormal electrical activity disrupts normal brain function and can result in various symptoms, including convulsions, loss of awareness, and altered behavior. The nature of seizures can vary significantly, but the underlying factor is this uncontrollable and unexpected disorganization of electrical impulses in the brain.

While a sudden loss of consciousness can occur during some seizures, it is not present in all types. Similarly, a gradual onset of confusion and a constant headache are not defining features of seizures. Understanding this characteristic helps in recognizing and responding appropriately to seizure scenarios, especially in high-stakes environments like corrections settings, where rapid assessment and action may be critical.
