Anorexia nervosa
People who develop anorexia tend to be perfectionistic. They are also more likely to have problems socializing. There has been research about the link between anorexia and autism spectrum disorder (ASD), a disorder that involves problems with socializing. Another symptom of autism spectrum disorder is OCD, which has also been linked to anorexia. Starvation is known to create antisocial behavior so there needs to be research that compares those traits in anorexics with people who have recovered.
