Biomarkers of Environment Sensitivity

Sponsor: Semmelweis University

Summary

Most of the common mental disorders are heritable to a certain extent but environmental factors have an important role influencing whether the disorder will develop or not. These factors can be negative (e.g. loss of job or death of a loved one) that increase the risk of disorders but also positive (e.g. friends that provide support in need or doing sport regularly) that prevent the development of symptoms. This study investigates whether those who are sensitive to negative impacts may be also more sensitive to positive circumstances. If this is true, improving the environment of these people, for example offering psychotherapy, may help them more than to those who are not sensitive to the environment. More than 500 000 participants' genetic data is used to investigate which genetic factors are associated with sensitivity to environment. This information will be used to determine genetic sensitivity to environment in independent participants who went through functional magnetic resonance brain imaging. Therefore, the study will examine whether sensitive and non-sensitive peoples' brain respond differently to positive and negative stimuli. Finally, tests will determine how sensitivity to environment influences the effectiveness of an intervention that psychologists use to improve stress coping in young adults. This method aims to identify biomarkers to predict the effectiveness of this intervention. In summary, the study will enhance the understanding of why some people are more sensitive to environmental influences and how this information can be utilized to select the most suitable therapy for them.
