Name two long-term cognitive or mental health consequences of chronic heavy alcohol use.

• A. Enhanced memory and cognitive speed.
• B. No cognitive changes.
• C. Impaired memory and executive function; increased risk of depression and anxiety disorders.
• D. Improved decision-making ability.

Answer: (C)

Chronic heavy alcohol use damages brain areas that handle memory and thinking, and it also disrupts mood-regulating systems. Over time, alcohol can harm the hippocampus, which is crucial for forming new memories, and the prefrontal cortex, which governs executive functions like planning, decision-making, and impulse control. This combination leads to lasting memory problems and difficulties with executive tasks. At the same time, prolonged drinking changes neurotransmitter systems and stress responses, elevating the risk of mood disorders such as depression and anxiety. Nutritional deficiencies, especially thiamine, can worsen these effects and may cause serious conditions like Wernicke-Korsakoff syndrome, further impairing cognition. So the long-term picture commonly includes impaired memory and executive function along with a higher likelihood of depression and anxiety disorders. Choices suggesting enhanced memory, no cognitive changes, or improved decision-making don’t align with these well-documented consequences.
