Behavioral addiction include addiction to gamble, video game addiction, compulsive shopping, food addiction, physical activity addiction, sexual and emotional addiction... There are neurobiatogical, psychopathological and behavioral similarities between addiction with product and behavioral addiction. The aim of this review is to illustrate in a simple way the brain changes observed by our research group in pathological gamblers using neuroimaging (functional MRI) during paradigms engaging the reward system and cognitive biases. The results provide a better understanding of brain regions and mechanisms involved in reward processing and decision making in pathological gambling. (C) 2021 l'Acadernie nationale de medecine.
