Which condition is characterized by reduced oxygen supply to the brain?

• A. Hypoxia
• B. Anoxia
• C. Ischemia
• D. Hyperoxia

Answer: (A)

Oxygen deprivation to the brain is hypoxia. Hypoxia means not enough oxygen reaches tissues, including brain tissue, which can impair function and lead to symptoms like confusion or loss of consciousness if severe. This differs from anoxia, which is essentially no oxygen at all. Ischemia refers to reduced blood flow to an area, which can cause hypoxia because oxygen delivery is limited, but the core issue is the blood supply, not just the oxygen content. Hyperoxia is excess oxygen. So the term that best fits "reduced oxygen supply to the brain" is hypoxia.
