Brief Summary:
Alcohol Use Disorder (AUD) is a major public health problem, characterized by a high rate of relapse. Chronic and excessive alcohol consumption notably induces frontal brain alterations and cognitive impairments such as executive dysfunction and an attentional bias for alcohol, participating to the risk of relapse. In effect, AUD patients preferentially process alcohol-related cues, which could reflect a reorganization of the patients' semantic network. The investigators hypothesize that in AUD patients, semantic associations in memory are reorganized with a higher centrality of alcohol-related elements. To the investigators knowledge, no studies have explored semantic associations and/or semantic networks in AUD.
A study, conducted in patients with neurological damage, showed that frontal lesions are associated with excessive strength in semantic associations, and difficulties to generate remote associations. This excessive strength in semantic associations could reduce the ability to inhibit automatisms and to adapt to new context.
Objective: The objective of this study is to explore whether and how AUD patients have a different organization of semantic associations than healthy controls, and whether this reorganization influences the alcohol consumption over the months following the withdrawal. The investigators will also explore how it relates to neuropsychological assessment of flexibility, executive functions, and impulsivity. To these purposes, the investigators will use two original verbal tasks (Free Generation of Associates Task, FGAT and Associative Judgment Task, AJT) assessing word associations and allowing the estimation of semantic networks using graph theory, in combination with neuropsychological testing, in AUD patients and in healthy controls.
Methods: This study will include a group of 30 AUD patients and a group of 30 healthy controls. Both groups will be assessed twice, at baseline (T1; early in abstinence for AUD patients) and after a three-month period (T3). For the two groups, T1 and T3 assessments will include the two semantic association tasks (FGAT and AJT). For AUD patients, assessments will also involve neuropsychological testing of impulsivity, flexibility, and attentional bias. Besides, in AUD patients, data about alcohol consumptions will be collected six weeks (T2) and three months (T3) following the baseline assessment to classify patients as relapsers or abstainers.
