The discussion as to the primacy of genetic vs. environmental factors has shifted with the concept of ?gene expression? being shown as increasing our understanding of the origin of pathological conditions and personality traits. This means the acceptance of gene expression occurring during the primal period as well. The questions are now focused on the timing and the critical periods for genes-environment interaction. Autism and anorexia nervosa, two conditions that are to a great extent determined during the perinatal period. Conclusions from a review of the relevant literature are that anorexia nervosa might be considered a female variant of the autistic spectrum.
