Manuel Isaías López

Manuel Isaias Lopez, MD is a prominent Mexican child psychiatrist, trained in Philadelphia, Pennsylvania, who founded the Child and Adolescent Psychiatry subspecialty program at National Autonomous University of Mexico (UNAM) in 1972. He also founded and was the first president of AMPI (Asociación Mexicana de Psiquiatría Infantil) in 1975. He was the training director of the only Child and Adolescent Psychiatry training program in Mexico, at UNAM, from 1972 until 1998. In the last quarter of the twentieth century, he was considered the most influential psychiatrist on the Mexican scene. In the early eighties, he was simultaneously president of the Mexican Psychoanalytic Association, Director of Child and Adolescent Psychiatry at UNAM, Secretary General of the Mexican Board of Psychiatry, and Main Consultant to the Desarrollo Integral de la Familia (DIF) system. His later contributions have been in Bioethics, and he has evolved into a researcher within the field and an International Psychoanalytic Association officer.

Mann de Dayán describes the "Sensory Oversaturation Syndrome" as Isaias Lopez's main contribution to the psychodynamics of adolescence. According to this phenomenon, the adolescent manages to move away from his own narcissistic needs by overstimulating himself, as a first step before he projects his needs to outside sources.

The Italian magazine Medicina e Morale (Med. morale., 2002, vol. 52, no 3, pp. 477 - 492), describes his view on the psychological argumentation of assisted reproduction. His position is that artificial insemination interferes with the parents' view of their child, and that this directly influences the child's sense of self.
