For psychologists, psychiatrists, neurologists, and others engaged in the diagnosis and treatment of patients with psychogenic pseudoseizures, a guide based on the author's 15 years of observing and treating such patients, many of them over a span of several years. Kalogjera-Sackellares (neuroscience, U. of Florida Health Science Center) describes a classification scheme of clinical syndromes; presents a framework for diagnosis; and discusses situations and problems commonly encountered among patients who present with psychogenic pseudoseizures. She draws on three major areas of psychodynamic theory to explain how trauma leads to the development of pseudoseizure syndromes: psychoanalytic theory, object-relations theory, and self-psychology.
