There are various causes of depression. Therefore, it is difficult to pinpoint the cause of depression in a person. It maybe one factor or a combination of factors. It maybe be triggered by changes in chemicals in the brain. Medical research has shown that lack of certain. Depression can also be linked to inherited traits. In some cases, it occurs in families with a history of depression. IT can also be caused by emotional shock, stress or certain illness.
Linking neuroscience with psychology helps it as a science. For a long time, depression has often been associated in social stressors and emotional issues. However, recent research has shown that depression in some people may be explained by chemical changes in the brain. Therefore, incorporating neuroscience add more knowledge and understanding of depression. Consequently, it allows psychologists to develop more comprehensive theories of depression.
Knowledge of genetics influences psychology research because there are depression has been linked to family history. There is a high correlation between families that have a history of depression with new cases of depression. Genetics teaches us that certain traits are inherited through DNA strands that carry information to offspring and code the way they appear and behave. Knowledge of genetic allows psychologist to assess how depression can be passed through family lineage.
The most recent application of the intersection of biology and psychology is the research on the medical causes of depression. Researchers argue that certain chemical reaction in the brain may result in depression. Therefore, that type of depression can be cured using medicine. Therefore, psychologists may have to work together with doctors in identifying the cause of depression and consequently in curing the depression.
