[Anorexia nervosa and Down syndrome].

This article reports on a 24-year-old woman patient with anorexia nervosa and Down's syndrome. Following examination of previous case studies on the simultaneous occurrence of these illnesses, the authors make a further contribution to the controversial discussion of whether primary anorexia can occur at all in the mentally retarded or whether it should not rather be considered an anorectic reaction related to other disorders, e.g. depressive disturbances.
