Impact of Neuropsychological Alteration of Patients With Eating Disorders

Impact of Neuropsychological Alteration of Decision-making Abilities on the Functioning of Patients With Eating Disorders

Eating disorders are multifactorial disorders currently conceptualized in a biopsychosocial model, but pathophysiology remains relatively unknown, and robust etiological models to guide treatment are therefore lacking. Different endophenotypes and neurocognitive vulnerability factors have been found in eating disorders including decision making abnormalities. The investigators hypothesize that decision making abnormalities are associated with a lower level of functioning and quality of life which could lead to social and interpersonal difficulties. The investigators also hypothesize that these anomalies are associated with a particular clinical profile (more restrictive profile, more hyperactivity, less insight on the disease and desire for care ...).

The investigators will recruit a total of 200 patients with an eating disorder in the university hospital of Montpellier.

Participation consists of a one-day visit with a multidisciplinary assessment. No action is specific to research. This is the usual management of patients with eating disorders addressed to our department.

Inclusion criteria :

• Patient with an eating disorder according to DSM-V criteria
• Patient aged from 15 to 65 years
• Patient who performs the day-hospital evaluation
• Patient affiliated to a French social security system
• Patient able to understand the nature, the aim and the methodology of the study For minor one of the legal guardians gave his consent

Exclusion criteria:

• Patient in an unstable somatic state (eg severe metabolic disorder making impossible or unreliable neuropsychological assessments)
• Patient's refusal to participate
• Patient protected by law (guardianship or curatorship)
• Pregnant or nursing women. A dosage of βHCG will be performed to ensure the absence of pregnancy.
