Anorexia is a symptom, not a diagnosis. The symptom also occurs in animals, such as cats, [1] [2] dogs, [3] [4] cattle, goats, and sheep.

The activity-based anorexia model has been one of the most suitable animal models when studying anorexia nervosa (AN).

A main factor differentiating binge-purge anorexia from bulimia is the gap in physical weight. Patients with bulimia nervosa are ordinarily at a healthy weight, or slightly ...
Body image disorder is a characteristic symptom of anorexia nervosa and bulimia nervosa. In both of these disorders, an excessive focus on body shapes and sizes made the body image disturbance easier to identify, to describe, and study.

Interacting with dogs in various activities could strengthen activity in brain areas associated with relaxation and focus, a new study has found. Interacting with dogs may affect multiple areas of ...
