The present book encompasses works on the topic of body psychology, headache disorders, artificial illnesses, and self-harming behavior. Reinhard Plassmann provides a well-founded overview of these conditions and their treatment from a psychosomatic and psychoanalytic perspective. Plassmann divides his book into three parts. In the first section, he focuses on the topic of body psychology. The interplay between physical processes is the fundamental theme of psychosomatics and psychotherapy. The second part addresses headache disorders. This topic deserves more scientific and clinical interest because it is common and causes significant suffering for those affected. The third part deals with artifact diseases and related conditions. These present great challenges for practitioners due to their immense destructiveness.
