Research focus

• Genetics and epigenetics of anxiety disorders and depression
  Anxiety disorders and depression are among the most frequent mental disorders with lifetime prevalence rates of about 20%. Twin studies indicate a considerable heritability (40-87%) of these disorders with contributions from several different genes, which interact with each other as well as with environmental factors in a complex-genetic model. Additionally, epigenetic mechanisms such as DNA methylation have become a central focus in psychiatric research as a dynamic link between genetic make-up and environmental stress shaping the overall disease risk. Our aims are to identify genetic and epigenetic factors as well as their interplay with environmental influences contributing to the development of anxiety disorders and depression.
• (Epi)genetics of intermediate phenotypes of anxiety disorders and depression
  The influence of genetic factors on anxiety and depressive disorders can be further specified by the consideration of so-called ‘intermediate phenotypes’. Intermediate phenotypes comprise heritable neurobiological or neuropsychological traits (e.g. anxiety sensitivity, neural activation patterns, startle reflex) that are linked to the disorder of interest, and, unlike the overall categorical disease phenotype, are dimensional, closely defined constructs and are therefore considered to be closer to the underlying genotype. Their investigation constitutes another central focus of our group.
• Therapy(epi)genetics of anxiety disorders and depression
  In the treatment of anxiety disorders and depression, efficacious pharmacological (e.g. SSRIs, SNRIs) and psychotherapeutic (e.g. CBT) options are available. However, treatment-resistance is a common problem in clinical practice, with about 30% of patients responding insufficiently to the initial treatment. Our workgroup aims to identify predictive genetic and epigenetic markers of favorable therapy response, as well as to elucidate epigenetic mechanisms of change in the course of treatment towards the development of a “precision medicine” approach corresponding to a patient’s individual risk factor constellation.
• Prediction and prevention of anxiety disorders and depression
  Anxiety and depressive disorders present with high chronicity and confer a substantial socioeconomic burden. They are highly comorbid, both with each other as well as with other mental disorders. Anxiety disorders can already manifest early in childhood and are characterized by high progression towards other anxiety disorders or other psychiatric disorders (e.g. depression) across the lifespan. Therefore, next to the identification of risk factors, preventive measures are needed in order to increase resilience in at-risk populations and are thus clinically and biologically investigated by our group.
