Which type of seizure involves the whole brain and is on both sides?

• A. Tension headaches
• B. Glaucoma
• C. Generalized seizures
• D. Poliomyelitis

Answer: (C)

Seizures reflect abnormal electrical activity in the brain. When that activity engages the entire brain and both hemispheres from the onset, it is a generalized seizure. This type typically leads to loss of consciousness and widespread, bilateral motor symptoms (like stiffening followed by jerking) or other generalized signs. In contrast, focal seizures begin in a specific area of one hemisphere and may stay localized or spread to involve the whole brain later, but they don’t start with both sides involved. The other options aren’t seizures at all—tension headaches are headaches, glaucoma is an eye condition, and poliomyelitis is a nerve disease causing paralysis, not seizure activity.
