In this episode, we discuss the reason humans are susceptible to 'behavioural addictions', referencing our shared paper 'Evolutionary perspectives on substance and behavioural addictions: Distinct and shared pathways to understanding, prediction and prevention'. Dr. Giuseppe Pierpaolo Merola is an Italian psychiatrist and researcher currently practicing at San Donato Arezzo Hospital and serving as a Visiting Researcher at King's College London.
