Résumé
De manière générale, il apparaît que l’acte suicidaire est hautement imprévisible par les moyens scientifiques actuellement à notre disposition. Dans cet article, nous formulons l’hypothèse que la prédiction du suicide est compliquée parce qu’elle résulte de la prédiction d’un choix, lequel est lui-même imprévisible. Nous proposons un modèle du suicide selon l’apprentissage par renforcement. Dans ce modèle, nous intégrons d’une part les quatre principaux modulateurs ascendants (acétylcholine, noradrénaline, sérotonine, dopamine) avec leurs régions de projections et d’afférences respectives, et d’autre part, différentes observations d’imagerie cérébrales trouvées à ce jour dans le processus suicidaire.
Abstract
In general, it appears that the suicidal act is highly unpredictable with the current scientific means available. In this article, the author submits the hypothesis that predicting suicide is complex because it results in predicting a choice, in itself unpredictable. The article proposes a Reinforcement learning model-based analysis. In this model, we integrate on the one hand, four ascending modulatory neurotransmitter systems (acetylcholine, noradrenalin, serotonin, and dopamine) with their regions of respective projections and afferences, and on the other hand, various observations of brain imaging identified until now in the suicidal process.
