The American Psychiatric Association defines depression as common and serious medical illness that negatively affects how an individual feels, the way he/she thinks and acts, which can lead …show more content…

For now, we have failed to pinpoint the actual DNA sequence or location of potential depression genes since it is in fact quite difficult. It is most likely that genes do not directly cause depression, but act as a trigger to some biological situations, which causes it by initiating overproduction or decrease of certain neurobiological …show more content…

For example, in a case study by Leve, Kerr, and Shaw (2010), a sample of children that were adopted at birth and studied for the early signs of genetic risk for externalizing behavior in mature life. One of the things they monitored was the infants’ ability to self-soothe in frustrating situations. The research showed that the only cases in which the infant was unable to self-soothe were when depression was evident in the adoptive mother. The children who were unable to pacify themselves also showed evidence of biological predispositions to be more sensitive to stressful environments.
