How does the biological approach explain mental illness?

• A. Mental illness can arise from genetic vulnerability, neurochemical imbalances, and brain structural abnormalities
• B. It is caused solely by parenting and upbringing
• C. It cannot be influenced by biology
• D. It is purely due to social factors

Answer: (A)

Mental illness is explained by biological processes affecting the brain. This approach points to genetic vulnerability—some individuals inherit genes that increase risk for certain disorders; environmental stress can interact with these genes to trigger illness. It also highlights neurochemical imbalances, where atypical levels or functioning of brain chemicals like dopamine or serotonin can alter mood, thinking, or behavior. Additionally, it considers brain structural abnormalities—differences in brain regions or connectivity that relate to how emotions, thoughts, and perceptions are processed. Together, these biological factors account for heritability, the effectiveness of psychiatric medications that target brain chemistry, and findings from brain imaging. The other views emphasize parenting, social factors, or deny biology, which fall outside the biological perspective.
