Involves both hemispheres and the reticular activating system, typically results in a loss of consciousness

• A. Generalized Seizure
• B. Simple Partial Seizure
• C. Secondary Seizures
• D. Partial Seizure

Answer: (A)

Generalized seizures involve both hemispheres from the onset and engage the reticular activating system, which is essential for maintaining wakefulness. When the activity spreads across large networks including the brainstem arousal system, consciousness is typically lost during the seizure. This bilateral, arousal-system–involving pattern distinguishes generalized seizures from focal-onset events. Simple partial seizures stay localized and usually preserve consciousness, while focal seizures that spread to both hemispheres can become secondary generalized, but the hallmark described—bilateral onset with disruption of arousal—fits a generalized seizure.
