Which type of seizure is NOT accompanied by impairment of consciousness?

Simple partial seizures are characterized by the absence of altered consciousness. During a simple partial seizure, the individual remains fully aware and may experience localized symptoms such as involuntary movements or sensory disturbances, depending on the brain area involved. Because consciousness is preserved, the person can recall the event afterwards and might even be able to respond during the seizure.

In contrast, complex partial seizures involve a loss of consciousness or altered awareness. Atonic seizures lead to sudden loss of muscle tone, and though they may take place quickly, the individual loses consciousness briefly. Absence seizures, often seen in children, result in brief lapses in awareness and consciousness that make the person unresponsive for a short time. Hence, the clear distinguishing feature of simple partial seizures is that the individual maintains consciousness throughout the episode.
