[Neurobiological and psychodynamic correlations in obsessive-compulsive disorders and bulimia nervosa].

Neurobiology seems to be a great challenge for recent psychosomatic medicine. The rise of neurobiology through fascinating findings characterizes our "decade of the brain". Psychosomatic medicine tries to integrate biological, psychological and social factors of disease and health. Therefore brain research is essential for psychosomatic medicine. This paper gives a review of two psychiatric disorders which show close neurobiologic connections: bulimia nervosa (BN) and obsessive-compulsive disorder (OCD). Both disease are characterized by an increase in prevalence and have been interpreted as modern epidemic diseases. Neurobiological and psychodynamic connections will be discussed.
