Laboratory studies have found that early life stress in rodents can cause phosphorylation of methyl CpG binding protein 2 , a protein that preferentially binds CpGs and is most often associated with suppression of gene expression. Stress-dependent phosphorylation of MeCP2 causes MeCP2 to dissociate from the promoter region of a gene called ...
Risk factors for mental illness include psychological trauma, adverse childhood experiences, genetic predisposition, and personality traits. [7] [8] Correlations between mental disorders and substance use are also found to have a two way relationship, in that substance use can lead to the development of mental disorders and having mental disorders can lead to substance use/abuse.
Behavioral epigenetics is the field of study examining the role of epigenetics in shaping animal and human behavior. [1] It seeks to explain how nurture shapes nature, [2] where nature refers to biological heredity [3] and nurture refers to virtually everything that occurs during the life-span (e.g., social-experience, diet and nutrition, and exposure to toxins). [4]
Clinical heterogeneity refers to when a single cause can lead to more than one clinical syndrome. [7] Several genetic risk factors have been found with the endophenotypes of psychiatric disorders, rather than with the diagnoses themselves. That is, the risk factors are associated with particular symptoms, not with the overall diagnosis. [1]
For instance, extreme stress (e.g. trauma) is a requisite factor to produce stress-related disorders such as post-traumatic stress disorder. [6] Chronic stress also shifts learning, forming a preference for habit based learning, and decreased task flexibility and spatial working memory, probably through alterations of the dopaminergic systems. [39]
Gene–environment interaction occurs when genetic factors and environmental factors interact to produce an outcome that cannot be explained by either factor alone. [6] For example, a study found that individuals carrying the genetic variant 5-HTT (the short copy) that encodes the serotonin transporter were at a higher risk of developing depression when exposed to adverse childhood experiences ...

Protective factors, while not an inherent component of the diathesis–stress model, are of importance when considering the interaction of diatheses and stress. Protective factors can mitigate or provide a buffer against the effects of major stressors by providing an individual with developmentally adaptive outlets to deal with stress. [ 10 ]
