Obsessive - compulsive disorder

(Prof. Dr. Michael Wagner, M.Sc. Katharina Bey)

Obsessive compulsive disorder is a relatively common (1 – 3%) and often chronic mental illness, leading to serious loss of function and suffering in those affected. Although various risk factors in the form of genetic and environmental influences are well documented, the exact interference mechanisms of OCD are only to some extent understood. By examining cognitive and emotional functions, clinical characteristics, personality traits and brain structural and functional parameters, the working group's research efforts aim to gain a better understanding of the Etiology of obsessive compulsive disorder and thus also on the further improvement of the forms of therapy.

  • Identification of endophänotypes
  • Connections between different levels of disturbance: Genetics, brain physiology, cognition, behavior, symptoms
  • Optimizing therapeutic approaches
