Are so-called neurodevelopmental clinical expressions, such as high intellectual potential or autism spectrum disorders, not the contemporary vicissitudes of child neuroses? Out of step, the author offers a fictional neurodevelopmental reading of Freud's cases, and, against the current, a psychoanalytical reading of a serious obsessive neurosis masked by the HIP of a child today. She examines the sleight of hand that makes the brain the origin of the world, obscuring infantile sexuality.
