Which statement is true regarding complex partial seizures?

Complex partial seizures, which are a type of focal seizure, often originate in a specific area of the brain and can indeed begin as simple partial seizures. A simple partial seizure might involve localized motor or sensory disruptions without loss of consciousness, and if it progresses, it can evolve into a complex partial seizure, which typically involves impaired consciousness or awareness.

In contrast to the other options, complex partial seizures do not frequently last for at least five minutes; they usually last from 30 seconds to a few minutes. While they may involve a larger network within the brain, indicating spread to both hemispheres, the initial onset is localized. Furthermore, during a complex partial seizure, the patient experiences impaired awareness or consciousness but does not necessarily lose wakefulness entirely; they may seem confused or unable to respond appropriately to external stimuli. Thus, the notion that they do not remain awake can vary based on the individual's specific experience.
