What term refers to sudden abnormal electrical activity in the brain?

• A. Epilepsy
• B. Seizures
• C. Dementia
• D. Glaucoma

Answer: (B)

Seizures are a sudden burst of abnormal electrical activity in the brain that can cause brief changes in movement, sensation, or consciousness. That immediate event is what the question is asking about, so this term fits best. Epilepsy, on the other hand, is a condition defined by recurrent unprovoked seizures, so it describes a disorder rather than the seizure event itself. Dementia refers to a decline in cognitive function over time, and glaucoma is an eye disease affecting the optic nerve. A single seizure can happen without epilepsy, but epilepsy implies a pattern of seizures.
