The researchers say that traits indicative of both disorders parallel each other. Anorexia and autism are characterized by obsessive, repetitive behaviors, by difficulties with social interactions and an above-average interest in systems. For autistic boys that might mean a fixation with math or maps. For anorexic girls, that translates into an obsession with food, weight and their bodies.
Both groups exhibit below-average empathy, rigid attitudes and an atypical preoccupation with themselves.
Understanding the behavioral connection between the two conditions could inform treatment choices for anorexia. For example, the researchers suggest that recognizing the fact that info about systems is easier to process than info about emotions may help in developing useful coping strategies.
