Which explanation for depression emphasizes the role of genetics in influencing serotonin levels?

The chosen answer highlights the biological explanation for depression, which focuses on the underlying physiological factors that contribute to the condition. This perspective suggests that genetic predispositions play a significant role in determining individual differences in serotonin levels, a neurotransmitter closely linked to mood regulation. Research indicates that variations in certain genes can affect how serotonin is produced, released, or utilized in the brain, thereby influencing the likelihood of developing depressive symptoms.

By concentrating on these biological bases, this explanation aligns with findings from studies that have shown familial patterns in depression and variations in brain chemistry. Understanding the biological factors, including genetics and neurochemical imbalances, is crucial in developing effective treatments such as medications that target serotonin levels. This approach’s emphasis on the physical aspects of depression differentiates it from other explanations, such as cognitive, which focuses more on thought patterns, or behavioral, which emphasizes actions and learned responses. The social aspect would consider environmental influences, making the biological explanation distinct in its focus on intrinsic body chemistry and genetics.
