Diathesis-stress models of schizophrenia-Schizophrenia: a neural diathesis-stress model.

The diathesis—stress model is a psychological theory that attempts to explain a disorder, or its trajectory, as the result of an interaction between a predispositional vulnerability and a stress caused by life experiences. A diathesis can take the form of genetic, psychological, biological, or situational factors. The diathesis, or predisposition, interacts with the individual's subsequent stress response. Stress is a life event or series of events that disrupts a person's psychological equilibrium and may catalyze the development of a disorder. The diathesis—stress model asserts that if the combination of the predisposition and the stress exceeds a threshold, the person will develop a disorder.

Studies show that that this brain disorder is consisting of hereditary or genetic components. Furthermore, the absence or the presence of specific life stressors could be the best explanation why there are other people who are not genetically vulnerable of developing the brain disorder which is schizophrenia. The symptoms and signs of this brain disorder vary for every person and it also comes to a point of undergoing changing with time wherein it can become more complex than the usual.

Schizophrenia can be diagnosed though psychiatric evaluation wherein the psychiatrist will be asking questions about psychiatric and family history, mental problems and a lot more.

Diathesis–stress model - Wikipedia

The diathesis—stress model is a psychological theory that attempts to explain a disorder, or its trajectory, as the result of an interaction between a predispositional vulnerability and a stress caused by life experiences. A diathesis can take the form of genetic, psychological, biological, or situational factors.

The diathesis, or predisposition, interacts with the individual's subsequent stress response. Stress is a life event or series of events that disrupts a person's psychological equilibrium and may catalyze the development of a disorder. The diathesis—stress model asserts that if the combination of the predisposition and the stress exceeds a threshold, the person will develop a disorder.

The use of the term diathesis in medicine and in the specialty of psychiatry dates back to the s; however, the diathesis—stress model was not introduced and used to describe the development of psychopathology until it was applied to explaining schizophrenia in the s by Paul Meehl. A child who has a family history of depression and who has been exposed to a particular stressor, such as exclusion or rejection by his or her peers , would be more likely to develop depression than a child with a family history of depression that has an otherwise positive social network of peers.

The diathesis—stress model has also served as useful in explaining other poor but non-clinical developmental outcomes.

Protective factors , such as positive social networks or high self-esteem, can counteract the effects of stressors and prevent or curb the effects of disorder. The term diathesis is synonymous with vulnerability , and variants such as "vulnerability-stress" are common within psychology.

Diatheses are understood to include genetic , biological , physiological , cognitive , and personality -related factors. Other diatheses include early life experiences such as the loss of a parent, [8] or high neuroticism.

Stress can be conceptualized as a life event that disrupts the equilibrium of a person's life. This also parallels the popular and engineering usage of stress, but note that some literature defines stress as the response to stressors, especially where usage in biology influences neuroscience. It has been long recognized that stress plays a significant role in understanding how psychopathology develops in individuals. To understand this, theorists and researchers explored other factors that affect the development of a disorder [17] and proposed that some individuals under stress develop a disorder and others do not.

As such, some individuals are more vulnerable than others to develop a disorder once stress has been introduced. 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. Many models of psychopathology generally suggest that all people have some level of vulnerability towards certain mental disorders, but posit a large range of individual differences in the point at which a person will develop a certain disorder. Conversely, an individual who finds it difficult to develop and maintain supportive relationships may be more vulnerable to developing depression following a job loss because they do not have protective social support.

An individual's threshold is determined by the interaction of diatheses and stress. Windows of vulnerability for developing specific psychopathologies are believed to exist at different points of the lifespan. Moreover, different diatheses and stressors are implicated in different disorders. For example, breakups and other severe or traumatic life stressors are implicated in the development of depression.

Stressful events can also trigger the manic phase of bipolar disorder and stressful events can then prevent recovery and trigger relapse. Having a genetic disposition for becoming addicted and later engaging in binge drinking in college are implicated in the development of alcoholism. A family history of schizophrenia combined with the stressor of being raised in a dysfunctional family raises the risk of developing schizophrenia.

Diathesis—stress models are often conceptualized as multi-causal developmental models, which propose that multiple risk factors over the course of development interact with stressors and protective factors contributing to normal development or psychopathology.

This child has also been exposed to environmental factors associated with parental depression that increase his or her vulnerability to developing depression as well. Protective factors, such as strong peer network, involvement in extracurricular activities, and a positive relationship with the non-depressed parent, interact with the child's vulnerabilities in determining the progression to psychopathology versus normative development.

Some theories have branched from the diathesis—stress model, such as the differential susceptibility hypothesis , which extends the model to include a vulnerability to positive environments as well as negative environments or stress.
