Everyone with any mental health disorder always wonders if genetics can be linked to the disorder they have. It has been said that risk of genetics being a factor in anxiety disorders is less likely to be a switch more than a problematic mix of genetics that can put a person at risk.

It also interacts with bad early breeding experience to influence attentional and emotional resources, stress nervousness, and alcohol choice and addiction. Then again, the little mechanisms by which the stress increases disorder risk in adulthood is not known but may include epigenetics (deals with changes in gene expression patterns that are independent of the underlying DNA sequence) programming of gene expression. To continue the research, Jordan Smoller distinguishes this section of the genetics of anxiety, “…the majority of the genetic association studies of the anxiety disorders have been candidate gene studies based on a limited number of biological hypotheses. [These are] commonly focused on genes related to monoaminergic neurotransmitter systems [(refer to the particular neurotransmitters dopamine, noradrenaline, and serotonin)], neuropeptides, and HPA axis function” (Smoller, p. 308). Individually, settled test creature models catch critical parts of human nervousness and dread conduct, and neuroimaging considers have gained free ground in mapping the primary and practical segments of uneasiness/fear symptoms. Smoller also explains, “[t]hese resources create opportunities for focusing genetic studies on biological pathways…for evaluating the functional significance of risk loci that may [identify] in the future” (Smoller, p. 310). He also distinguished, “[c]onvergent evidence from genetic epidemiologic, molecular genetics and
Today anxiety disorders are recognized as one of the most common mental health disorders. Anxiety has been around since human’s worried about being eaten by saber tooth tigers. “It’s important to note that at its core level, anxiety is a part of evolution. Anxiety is the activation of the fight or flight system the system your body uses to keep you safe from harm (Calm Clinic)”. Oddly, anxiety is a normal part of life; you may feel anxious when having to make a significant decision or taking a test, for most people these normal feelings usually fade, however for those who suffer from an anxiety disorder, these feels never subsides. They can cause such distress that it interferes with an individual’s ability to lead a normal healthy life.
Anxiety disorders are prevalent in many adults all over the world. People with anxiety disorders have an impaired ability to work and function in their daily lives compared to a person without an anxiety disorder (Fuller-Thomson, Olfson, Villegas, Morcillo, Wang & Blanco, 2012). Many research studies have been conducted to understand how anxiety disorders development and to find the best treatment (Wilson & Scarpa, 2014). Through the research, it has become apparent that both genetic and environmental factors have an effect in the development in these disorders. Although evidence does suggest environmental factors have a greater impact (Maniglio, 2013).
Generalized Anxiety Disorder (GAD) is one of the most diagnosed mental disorders today, and can often be closely linked to concurrent symptoms or disorders including physiological, behavioral, other anxiety disorders, depression and substance abuse. (Merino, Senra & Ferreiro, 2016) (Cacioppo & Fregberg, 2013, p. 688). GAD most notably produces symptoms of excessive worry and anxiety related to non-specific risks, which often leads to functional decline both socially and professionally (Roberge et al., 2015). GAD reveals instances of links to biological origins such as heredity and biochemistry, as well as, ties to an individual’s cognitive development and socioeconomic environment (Cacioppo & Fregberg, 2013).
This theory creates an issue, as it only looks at nature’s impact as the root cause of phobic disorders and relishes in not accounting for environmental causes, which are posed by nurture. This aspect of nurture which is ignored can be questioned in the twin studies as although Torgersen found that identical twins who share genes are 5x more likely to share an anxiety disorder, it is unclear whether it is the nature of the genetic makeup which causes the disorder, or the nurture of the twins, as they would have both gone through the same things in their environment causing the contamination effect. This is further highlighted through the diathesis stress model formed by Di nardo et al which provides a much more
Genetics can help answer questions about our traits and why we look different and advance in different ways from each other in the world. Chapter 1 explains the basics about how genes work, and the portrayal of DNA and RNA. Chapter 2 describes RNA more in detail and it consist of the explanation of the human genome. Specifically, Chapter 3 clarifies how evolution works and how it relates to genetic and medical research. Furthermore, Chapter 4 and 5 explains the knowledge researchers have about genes role in health and diseases, and how society is affected with the advances in medicine and science given approximate credit to these researchers.
Science with all its marvels and wonders continues to press forward making extraordinary breakthroughs. Psychology plays a key role in many of sciences steps forward, each branch of psychology focusing on a specific techniques and theories. In the document the center of attention is surrounding the application of clinical psychology, this branch of psychology is unique as it all realms of an individual’s issue. Specifically speaking, anxiety is the psychological disorder that is under review through the processes of a clinical
A person with Generalized Anxiety Disorder is also more prone to depression, bipolar disorder, and substance abuse. (Davies, Matthew N., et al. " Generalised Anxiety Disorder – A Twin Study Of Genetic Architecture, Genome-Wide Association And Differential Gene Expression." Plos ONE 10.8 (2015): 1-15. Academic Search Complete.
Oler, et al. (2010) investigates the potential heritability of the anxious temperament (AT) phenotype and its related brain circuity. Perhaps some of the most prevalent mental illnesses are anxiety disorders, where symptoms become noticeable in the prepubescent period. Although many experience feelings of anxiety during adolescence, anxiety disorders are characterized by a continual anxious temperament beginning in youth and extending into adulthood. This anxious temperament is marked by a high degree of both freezing behaviour and a lack of communication in response to strangers or unfamiliar stimuli. Additionally, those with AT will often see an increase in autonomic activity. It is believed that AT has some genetic predisposition. However,
The results of the twin study revealed that the DNA segments of the HTR1A gene were identical; neither had the gene missing or inactivated. The data of all the twins’ DNA was tested for differences and the results fit the Hardy-Weinberg equilibrium model, meaning that there were no deviations or major differences in the HTR1A gene between twins. Each twin had identical genes and there was no difference between the twins who had anxiety disorders and depression and those that did not. The data from this study suggests that the HTR1A gene is not the gene, if there is one, that is responsible for anxiety disorders. It is possible that the gene with a combination of other factors, in some people, causes anxiety or depressive behavior. Without knowing a third variable, or perhaps environmental trigger, the HTR1A alone cannot be said to be responsible for anxiety disorders.
However, offspring of parents with major depressive disorder + anxiety disorder had considerably more particular fears than children of non- ill parents. Specific fears in children with parents with only major depressive disorder were found in 26 (35%), with parents with only anxiety disorder were found in 26 (35%), with parents with major depressive disorder and anxiety disorder combined were found in 51 (58%) and with normal parents (control group) were found in 25 (31%) of children. The only group that deviates significantly from the others it is the one where the children had parents with major depressive disorder and anxiety disorder (MDD + AD).

In general, it can be said that anxiety disorders develop from a complex set of risk factors, including genetics, brain chemistry, personality, and life events. The diathesis stress model also underlies susceptibility to anxiety disorders. Researchers are finding that genetic and environmental factors, frequently in interaction with one another, are risk factors for anxiety disorders. However, some of the specific factors include:

One of the next major questions that psychologists should attempt to answer was proposed in Sharp et al. (2015) in which the authors of the paper discussed the transdiagnostic dimensions of anxiety, particularly the neural mechanisms and executive functions involved. The two dimensions of anxiety that the paper specifically focused on were anxious apprehension and anxious arousal. According to the paper, these two factors have helped to bridge the gap between psychological and neurobiological models of anxiety. The study of neuroscience, which is in its relative infancy, has also led to many changes in our understanding of psychological diagnosis and disorders. This new field, however, has also resulted in many unanswered questions. These questions are numerous and varying and include researchers’ attempts to identify the specific mechanisms through which disorders occur, genes that may predispose individuals to certain disorders, new methods of measuring the constructs that make up “disorders”, and ways of effectively treating these disorders.
There has been a lot of scientific research done into genetics, genetic crosses and inheritance enabling us to understand why we have the certain characteristics and traits that we do, how we inherited them and how we can pass them on. It’s because of this research that we can understand and learn about our genetic makeup and why it effects the way we are.
