Which brain disorder is characterized by recurring seizures?

• A. Dementia
• B. Glaucoma
• C. Epilepsy
• D. Tension headaches

Answer: (C)

Recurring unprovoked seizures define epilepsy, a brain disorder caused by abnormal electrical activity in the brain that leads to sudden episodes of altered movement, sensation, or consciousness. Seizures can show up as convulsions, brief staring spells, confusion, or changes in awareness, and they may occur repeatedly over time. Dementia involves progressive cognitive decline, glaucoma is an eye condition affecting vision, and tension headaches are headaches from muscle tension—none of these describe a brain disorder defined by repeated seizures. So the description best fits epilepsy.
