The first part deals with the psychopathologic aspects of mental disorder, including some fundamental principles of psychopathology. The second part explores the therapeutic advantages and potentials of psychological analysis, such as the free association and dream analysis, as well as the interpretation of the life history. The third part describes the so-called miscellaneous treatment options, including mental therapy by family reorganization, educational therapy, and bibliotherapy. The fourth part discusses the physiology of the emotions, with particular emphasis on the pharmacological treatment of organic emotional disorders.
