Executive functioning and central coherence in anorexia nervosa: Pilot investigation of a neurocognitive endophenotype.

A neurocognitive profile characterized by problems in set shifting, executive functioning, and central coherence may pre-date and maintain anorexia nervosa (AN). To test this pattern as a possible endophenotype for AN, 10 youth with current AN, 14 healthy youth, and their biological parents, participated in a neuropsychological battery. Youth with AN demonstrated significantly weaker central coherence, related to enhanced detail-focused processing.
