Which of the following can be a consequence of dopamine imbalance?

• A. Heightened sense of reward.
• B. Increased tolerance to pain.
• C. Mood disorders like depression and addiction.
• D. Improved cognitive abilities.

Answer: (C)

Dopamine plays a crucial role in the brain's reward pathways, influencing emotions, motivation, and pleasure. An imbalance in dopamine levels can lead to significant psychological consequences. For instance, low levels of dopamine are associated with mood disorders such as depression, where individuals may experience a lack of motivation and pleasure in activities that they previously enjoyed. Conversely, an excess of dopamine can contribute to addictive behaviors, as seen in substance use disorders, where the pursuit of pleasure dominates decision-making processes. Thus, mood disorders like depression and addiction are direct consequences of how dopamine levels affect emotional well-being and behavioral patterns. Other options may describe effects associated with dopamine activity, but they do not encompass the broad impact on mood and behavior that stems from dopamine imbalance.
