For this project I am going to add on to the personality page of Behavioural epigenetic. I am going to add new sections as well as add on to the old ones.

Research into epigenetic in psychology
-going to add information from a twin study to demonstrate how stress, behaviour and personality are related.

How the effect of early childhood stress can affect child's development. Considering how epigenetic processes may contribute to the child's behaviour and personality

The neurobehavioral system of anxiety is related to higher order personality traits. Neuroticism is a personality trait that is characterized by strong negative emotions and a high state of stress and interpersonal alienations.

Another study involving a large cohort of monozygotic twins noted epigenetic differences arise during the lifetime and the twins diverge as they become older. The study identified approximately one third of monozygotic twins had epigenetic differences in DNA methylation and histone modification. The epigenetic markers were more distinct in older twins who had different lifestyles. This finding stresses the significant role of environmental factors in translating a common genotype into a different phenotype.

External influences such as smoking, physical activity habits and diet are can have a long term influence on epigenetic modifications. Internal influences such as small defects in transmitting epigenetic information through successive cell division could also have a long term effect on epigenetic modifications.

Abuse
Epigenetic processes can be linked to the emergence of a child’s behavior. Growing up in an environment of stressful conditions may result in changes in DNA methylation which can lead to psychological and physical disease impacting behaviour.

adding to stress,

Another study demonstrated children of mothers who were depressed and experienced maternal sensitivity, analogous to rat licking, had DNA methylation of specific CpG sites of NR3CI which links early life stress to biobehavioral reactivity and self-regulation.

Psychological Disorders
- going to change the heading to Psychological disorders

- going to add mood disorders

- adding a section on personality disorders

- adding a section on Borderline Personality Disorder

Mood Disorders
Explain how some personality traits such as novelty seeking, are predictors of certain mood disorders such as stress-related mood disorders. Certain personality traits are vulnerable to depressive-like symptoms leading to mood disorders.

Mood Disorders
Some personality traits, such as novelty seeking, may be a predictor to Mood Disorders. Studies have shown that the hippocampal BDNF and its epigenetic regulation predicts the differences between individuals and their vulnerability to psychosocial stress. Psychosocial stress can be a trigger for the development of Mood Disorders. Those with high BDNF levels of the vulnerable high novelty seeking, are not affected by psychosocial stressors. Those who exhibit low novelty seeking have an up regulation of BDNF which increases the likelihood of Mood Disorders.

Personality Disorders
There is a strong correlation between personality traits and personality. It is assumed to fit the dimensional model. Explain how neurobehavioral systems are the key feature in most personality traits.

Borderline Personality Disorder
Explain how personality traits are associated with BPD. How neurobehavioral systems such as BIS and BAS are also associated with this disorder and how certain traits of this disorder have to do with experience-dependent which shapes the genetic expression of Borderline Personality Disorder.

Borderline Personality Disorder
Borderline personality disorder commonly known as BPD is an mental illness characterized by long term abnormal behavioural patterns. It is not only a disorder but also a complex behavioural phenomenon that is the baseline to much larger personality disorders. Borderline personality disorder is affected by experience-based modifications that has effects on our genetic expression meaning BPD can be expressed based on experiences in the individuals' life. The early critical periods of development are especially sensitive to being modified by experience putting a person at risk for personality disorder.
