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)

Generalized seizures involve the whole brain and affect both hemispheres from the start, so the abnormal electrical activity is bilateral. This leads to loss of consciousness and widespread symptoms that involve both sides of the body. In contrast, focal or partial seizures begin in one area and may stay localized or spread gradually, not necessarily involving the entire brain at once. The other options aren’t seizures: tension headaches are a type of headache, glaucoma is an eye disease, and poliomyelitis is a viral infection that can cause paralysis but does not describe a seizure.
