Which term means fainting due to insufficient blood flow to the brain?

• A. Synocope
• B. Hyperglycemia
• C. Epilepsy
• D. Convulsion

Answer: (A)

Fainting from not enough blood reaching the brain is called syncope. When cerebral blood flow drops, consciousness is lost briefly, and recovery occurs once blood flow and pressure normalize. This is distinct from hyperglycemia, which is simply high blood sugar and doesn’t describe a temporary loss of consciousness due to brain perfusion. Epilepsy is a condition with recurrent seizures from abnormal brain activity, and a convulsion refers to the shaking movements that can accompany a seizure. A fainting spell isn’t a seizure, but the term that specifically means fainting due to reduced brain blood flow is syncope.
