Professor G. V. Starshenbaum studied psychosomatic disorders and created a book that offers the causes of bodily dysfunctions, self-diagnosis tests, and effective practices to relieve psychosomatic symptoms. This guide is intended not only for specialists, but for everyone who wants to improve their well-being and quality of life. The book combines basic knowledge about the psychophysiological mechanisms of disorders, provides tests for diagnosing them, offers effective methods of self-help, and includes reminders.
