Which term means loss of consciousness caused by insufficient blood to the brain?

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

Answer: (A)

The idea being tested is a medical term for fainting caused by not enough blood reaching the brain. That term is syncope, which means a temporary loss of consciousness due to reduced cerebral blood flow. The option shown is a misspelling of syncope, but the intended concept is exactly this fainting from insufficient brain perfusion.

Epilepsy describes seizures from abnormal brain activity, not a loss of consciousness caused by blood flow. Hyperglycemia means high blood sugar, and hypoglycemia means low blood sugar; both relate to blood sugar problems, not the specific mechanism of fainting from reduced brain blood supply.
