Question

analyzing impact of family history on depression
a recent study found that disorders, such as depression, can run in the same family. what valuable insight about mood disorders can be inferred from these results?
health professionals should exclude family history when diagnosing mood disorders.
both family history and external factors can trigger the onset of depression and bipolar disorder.
children are unlikely to receive a mood disorder diagnosis if their parents were previously diagnosed.
when looking at a family tree, mood disorders rarely appear across several ancestral lineages.

Explanation:

• Option 1: Excluding family history is incorrect as the study shows family history is relevant.
• Option 2: Family history (genetic/biological aspect) and external factors (environmental/situational) can both contribute. This is a valid insight as mental health disorders often have multiple triggers.
• Option 3: If parents have mood disorders, children are more likely (not unlikely) to be at risk.
• Option 4: The study says disorders can run in families, so they would appear across lineages, not rarely.

Answer:

B. Both family history and external factors can trigger the onset of depression and bipolar disorder.
