Abstract
Zusammenfassung. Erst in den letzten Jahren wird auch in der Forschung vermehrtes Augenmerk auf die Überschneidung von Tic- und Zwangsstörungen gerichtet. Während in Übersichtsarbeiten zum gemeinsamen Auftreten von Tic- und Zwangsstörungen die zahlreichen Befunde zu Phänomenologie, begleitender Psychopathologie, Epidemiologie und daraus resultierenden Therapieimplikationen breiten Raum einnehmen, sind die Untersuchungsergebnisse hinsichtlich ätiologischer und pathophysiologischer Gemeinsamkeiten in entsprechenden Arbeiten unterrepräsentiert. Daher wird mit dieser Arbeit ein Überblick über den aktuellen neurobiologischen Forschungsstand zu den Gemeinsamkeiten und Unterschieden von Tic- und Zwangsstörungen gegeben.
Abstract. There has been increasing interest in the overlap between tic disorders and obsessive-compulsive behavior/disorders over recent years. Most of these studies have focused on phenomenology, associated psychopathology, epidemiology, and their implications on treatment. Fewer data are available concerning etiology and pathophysiology. This work provides a review of the current state of research on commonalities and differences of tic disorders and obsessive-compulsive disorders as well as their comorbidity.
