Depression. The main biological explanations of depression are as follows: Genetic – there is considerable evidence that the predisposition to develop depression is inherited. Biochemistry, e.g. Amine hypothesis – low levels of mono amines predominantly noradrenaline and serotonin.
What is the biological cause of depression?
The biological factors that might have some effect on depression include: genes, hormones, and brain chemicals. Depression often runs in families, which suggests that individuals may inherit genes that make them vulnerable to developing depression.
How does the biological approach treat depression?
The drugs are divided in three groups: the classical tricyclic antidepressants, the MAO inhibitors and the recent antidepressants. Some drugs with potential antidepressant properties are also studied. The other biological treatments of depression include electroconvulsive therapy and sleep deprivation.
How does biological psychology explain depression?
Current research suggests that a decrease in the production of serotonin by these neurons can cause depression in some people, and more specifically, a mood state that can cause some people to feel suicidal. In the 1960s, the “catecholamine hypothesis” was a popular explanation for why people developed depression.
How does the biological approach explain mental health?
The biological approach of the medical model focuses on genetics, neurotransmitters, neurophysiology, neuroanatomy, and so on. Psychopathology says that disorders have an organic or physical cause. The approach suggests that mental conditions are related to the brain’s physical structure and functioning.
What does God say about depression?
“The Lord himself goes before you and will be with you; he will never leave you nor forsake you. Do not be afraid; do not be discouraged.” The Good News: While depression can make you feel lonely, God is still there with you. And he’s not going anywhere.

Is biological depression curable?
Most people with MDD get better when they stick to their treatment plan. It typically takes several weeks to see an improvement in symptoms after beginning a regimen of antidepressants. Others may need to try a few different types of antidepressants before they start to notice a change.
Why is the biological approach useful?
By looking at the biological bases of human behavior, psychologists are better able to understand how the brain and physiological processes might influence the way people think, act, and feel.
What is the main focus of biological psychology?
Biological psychology, also called physiological psychology, is the study of the biology of behaviour; it focuses on the nervous system, hormones and genetics. Biological psychology examines the relationship between mind and body, neural mechanisms, and the influence of heredity on behavior.
What are the psychological views of depression?
The cognitive triad are three forms of negative (i.e. helpless and critical) thinking that are typical of individuals with depression: namely negative thoughts about the self, the world and the future. These thoughts tended to be automatic in depressed people as they occurred spontaneously.
How does Behaviourism explain depression?
Behavioral theory posits that certain environmental changes and avoidant behaviors inhibit individuals from experiencing environmental reward and reinforcement and subsequently leads to the development and maintenance of depressive symptoms.
Do genetics affect depression?
Depression is known to run in families, suggesting that genetic factors contribute to the risk of developing this disease. However, research into the genetics of depression is in its early stages, and very little is known for certain about the genetic basis of the disease.
What are the five models of mental illness?
A Take-Home Message. There are several mental health theories, but they all come from one of five schools of thought. They are behaviorism, biological, psychodynamic, cognitive, and humanistic.
Which treatment assumes a biological cause for a disorder?
Biomedical therapy involves medication and/or medical procedures to treat psychological disorders. Biomedical therapies approach psychological disorders as having biological causes and focus on eliminating or alleviating symptoms of psychological disorders.
Is mental illness biological?
“All mental processes are brain processes, and therefore all disorders of mental functioning are biological diseases,” he says. “The brain is the organ of the mind.
