Which statement about generalized seizures is true?

• A. Involve both hemispheres from onset
• B. Originate in the occipital lobe
• C. Are always without loss of consciousness
• D. Never involve loss of consciousness

Answer: (A)

Generalized seizures involve both hemispheres from the onset. The seizure activity starts in one region and rapidly engages networks across both sides of the brain, leading to bilateral involvement and often impaired consciousness or bilateral motor manifestations. This is why generalized seizures are not restricted to a single lobe. In contrast, seizures that originate in a specific area of cortex (for example, a focal lobe) can begin with focal symptoms and may or may not generalize later. Therefore, the statement that generalized seizures involve both hemispheres from onset is true. The other options don’t fit because a generalized onset is not confined to the occipital lobe, and generalized seizures commonly involve loss or alteration of consciousness, so statements denying that are incorrect.
