Book excerpt: This collection is Volume II of the Research Topic The Importance of the Body-Mind Relationship in Mental Functioning and Development of Body-Focused Disorders in Adolescence. Adolescence is a critical period when the conflict between the body and mind becomes particularly pronounced due to the physical changes associated with puberty. These pubescent transformations can affect body image and the perception of self, necessitating a renegotiation of the relationship between body and mind. Failure to navigate this process successfully can lead to dissociation from the sexual body, resulting in feelings of alienation, hatred, disinvestment, and even self-destructive behaviors such as eating disorders, self-injury, and suicide.
