A readable, scholarly, and practical introduction to psychodynamic theory and practice. It introduces the basic principles of psychodynamic psychiatry and the four fundamental theoretical frameworks derived from psychoanalytic theory: ego psychology, object relations theory, self psychology, and attachment theory. Drawing on the latest breakthroughs in neuroscience to validate the latest psychodynamic thinking, the author includes neuroanatomical illustrations that highlight the need to integrate psychoanalytic theories of development with brain development and the impact of environment on gene expression.
