Apollonia was diagnosed with major depressive disorder five years ago. She knows her mother took medicine to combat depression and she worries her daughter will experience depression too. Why?
The Correct Answer and Explanation is:
Correct Answer:
Because depression can run in families.
Explanation:
Apollonia’s concern about her daughter potentially experiencing depression is valid and grounded in scientific research. Major Depressive Disorder (MDD) is a complex mental health condition influenced by a combination of biological, psychological, and environmental factors. One of the strongest biological risk factors for depression is genetics. Research indicates that depression can indeed run in families, meaning that if a close relative—such as a parent or sibling—has experienced depression, the likelihood of another family member developing the condition increases.
Studies show that individuals who have a first-degree relative (parent, sibling, or child) with major depressive disorder are two to three times more likely to develop depression themselves compared to the general population. This heightened risk is attributed to the inheritance of certain genes that affect brain chemistry and function, particularly involving neurotransmitters like serotonin, dopamine, and norepinephrine, which play key roles in regulating mood, energy, and thought processes.
However, it’s important to note that genetics alone do not determine a person’s mental health. Environmental factors—such as stress, trauma, upbringing, and social support—also play crucial roles. Even if someone is genetically predisposed to depression, they may never develop the disorder if they live in a nurturing, supportive environment and maintain a healthy lifestyle.
For Apollonia, understanding the genetic link helps explain her worry. Her mother’s history, combined with her own diagnosis, indicates a multi-generational pattern, which raises valid concerns about her daughter’s future risk. Nonetheless, this knowledge can also be empowering. Being aware of the genetic predisposition allows Apollonia to be proactive—by promoting mental health awareness, seeking early intervention if symptoms arise, and creating an emotionally supportive environment for her daughter.
In summary, Apollonia’s worry stems from a well-established medical fact: depression has a hereditary component, and this increases her daughter’s risk.
