Ordalie, recherche de sensations et impulsivité. Analyse critique des concepts

Abstract : Background: in the fields of psychology and psychiatry, the use of the terms impulsivity, sensation-seeking and ordalie to refer to risk-taking behaviours can sometimes be confusing. Objective: the objective of this study was to establish a clinical, neuroanatomical and neuro-biochemical definition of the concepts of ordalie, sensation-seeking and impulsivity, in order to analyze the similarities and differences between these concepts. Methods: we prioritized literature review articles with or without meta-analysis from the Medline database and supplemented with the Google-Scholar database. The articles were included in this review if their objectives were in line with ours. The research was conducted in November 2018. Results: 27 articles were selected. There are similarities in the clinical definitions of these concepts with measurable heterogeneous constructions, and an exacerbation in adolescence for engagement in harmful behaviours, but there are also nuances that highlight their differences. In neuro-anatomical and biochemical terms, we have no data for ordalie. It appears that the characteristics of sensation-seeking and impulsivity have similarities, involving the same neural circuits with a key role for dopamine, but also fundamental differences, particularly in terms of activity, volumetric damage and metabolism. Conclusion: the limits of this work do not allow us to establish a quantitative diagram of the areas of divergence and convergence between these three concepts, only to conclude that they do exist. It would seem that the coexistence of sensation-seeking and impulsivity in the same individual could explain that individual's involvement in ordalique behaviours. Further studies approaching this hypothesis would seem useful in terms of preventing risk-taking behaviours such as addiction.
