EC Psychology And Psychiatry

Eating disorders such as anorexia nervosa and bulimia nervosa still remain a malaise poorly understood in its etiology, and even less in its treatment. Affective neuroscience has shown that human personality is rooted in primary motivational/emotional systems that have been shaped along their own phylogenetic history. Eating disorders are increasingly recognized as an expression of the motivational/emotional systems involved in the dynamics of Sexual selection starting from adolescence. The latter pushes sexually mature individuals to compete for obtaining partners, and competition constitutes a vulnerability area for females affected by eating disorders. The intra-sexual competition hypothesis of eating disorders emphasises the importance of hormones and the links with dissociated functioning.
