Which brain functions are first affected by alcohol?

The correct answer highlights that judgment and self-control are the brain functions most immediately impacted by alcohol consumption. When alcohol enters the system, it affects the frontal lobes of the brain, which are responsible for higher-level cognitive functions including judgment, decision-making, and impulse control. This impairment can lead to risky behaviors and poor decision-making, as individuals may underestimate dangers or misjudge social situations.

While other brain functions such as memory, coordination, vision, and reaction time are also affected by alcohol, they generally show more pronounced impairment at higher levels of intoxication. The influence on judgment and self-control, however, tends to manifest early in the drinking process, making it a critical factor in understanding the immediate effects of alcohol consumption. It underscores the importance of awareness regarding one's ability to make sound decisions, which is essential for driving and other activities that require cognitive clarity and self-regulation.
