A Double Blind, Randomized Cross-Over Trial of Tyrosine Treatment on Cognitive Function and Psychological Parameters in Severe Hospitalized Anorexia Nervosa Patients.

Background: Anorexia nervosa (AN) is characterized by self-induced malnutrition, affecting body image, mood, cognition and survival. Tyrosine, an essential amino acid is the precursor of catecholamines. The use of tyrosine to treat AN is based on experiments on diet restricted mice, in which it increased food consumption, improved cognitive function and elevated brain catecholamines.

Prevalence of psychologic, dental, and temporomandibular signs and symptoms among chronic eating disorders patients: a comparative control study.

Aims: To compare the prevalence of psychologic, dental, and temporomandibular disorder (TMD) signs and symptoms between young women suffering from chronic eating disorders (ED) and a control group of age-matched, healthy women, and to evaluate the impact of frequent vomiting on these signs and symptoms among the ED group.

Methods: Clinical examination and self-administered questionnaires were used to evaluate psychologic, dental, and TMD signs and symptoms among 79 women hospitalized because of chronic ED and 48 age-matched healthy women (as controls). ED patients were further analyzed according to their habit of daily vomiting (43 vomiting versus 36 nonvomiting patients).
