Behavioral Addictions and Related NeuroCOgnitive Aspects (BANCO2)

Study BANCO2: Behavioral Addictions and Related NeuroCOgnitive Aspects : Monocentric, Prospective, Controlled, Open-label Study Conducted With a Sample of Patients With Behavioural Addiction

Improving knowledge about behavioural addictions is a real public health issue. The etiopathogenic model of behavioural addictions is multifactorial, with various risk and vulnerability factors, involved in the initiation and maintenance of the disorders. Among these factors, neurocognitive alterations associated with behavioural addictions has recently aroused interest among researchers.

To our knowledge, there is no work wich compared several behavioural addictions with each other on a neurocognitive level. Moreover, neurocognitive data concerning certain behavioural addictions (such as sexual addiction) is almost non-existent. However, understanding the neurocognitive profiles of these patients would allow the investigators, on the one hand, to reinforce the existing literature and improve our understanding of the global process of addiction, and on the other hand, to propose alternative approaches to its management, taking into account the neurocognitive difficulties of the patients.

The investigators therefore propose to explore the neurocognitive alterations of patients suffering from several behavioural addiction (sexual addiction and eating disorders with bulimia episodes), by comparing them with each other, to matched healthy control groups and to a recognized behavioural addiction (gambling disorder; data from the BANCO study - NCT03202290).

Participant Group / Arm	Intervention / Treatment
Other: Healthy volunteers; Healthy volunteers will be matched on gender, age and education level to patients	Behavioral: Cognitive and clinical assessment; The content of the assessment will be the same for all subjects and will consist of a cognitive assessment (neurocognition, social cognition, metacognition, emotional reactivity) and a clinical assessment (impulsivity, personality, psychiatric and addictive comorbidities)
