The front lobe of the brain is the first part of the brain that is affected by alcohol. Which part is it?

• A. Frontal Lobe
• B. Occipital Lobe
• C. Cerebellum
• D. Brainstem

Answer: (A)

Alcohol slows brain activity, and the frontal lobe is where we do a lot of higher-level thinking—planning, judgment, and impulse control. When alcohol enters the system, these executive functions are affected first, so you notice things like reduced inhibitions and poorer decision-making before other skills. The other regions have important roles too—vision comes from the occipital lobe, movement coordination from the cerebellum, and basic life-sustaining functions from the brainstem—but those areas aren’t the first to show impairment with typical levels of intoxication. So the part described as the first affected by alcohol is the frontal lobe.
