What causes depression? The classic nature vs. nurture debate comes to mind when I hear this question. I believe that depressionis cause by a combination of factors. In general Certain stresses an/or traumas can cause the expression of the gene (a gene for OCD, a gene for depression, etc.) This study suggests that this is true for depression. The study suggests that the interaction of environmental stresses coupled with the gene for depression may cause depression.
The association between variations in the serotonin transporter gene and the development of depression in response to life stress—first elucidated in a now-famous 2003 report in Science—has been confirmed by meta-analysis.
Put your 2 cents in and tell me what you think. Does environment or genetics cause depression or is it combination of the two.
