Which model states that abnormal behavior results from biological processes of the body?

The biological model asserts that abnormal behavior is primarily a result of biological processes within the body, such as genetic factors, neurochemical imbalances, and physiological changes. This perspective emphasizes the role of the brain and nervous system in mental health, suggesting that mental disorders can often be traced back to physical issues. For instance, a chemical imbalance in neurotransmitters can lead to conditions like depression or anxiety, which are seen as rooted in the biology of the individual rather than stemming from psychological or environmental factors.

This model is crucial in understanding various mental health disorders as it aligns treatments that target these biological underpinnings, often through medication or other medical interventions. By focusing on the biological aspects, this model contributes significantly to the way mental health is approached, providing a framework that encourages research into the physiological aspects of psychopathology.
