Zusammenfassung der Projektergebnisse

In this project, we have evaluated the link between brain activity or behavioural parameters acquired with two functional paradigms (food cue-reactivity and delay discounting) and body mass changes in (initially) obese patients assessed across a time period of 39 month. By using the functional paradigms, which are also applied in research on substance-related disorders, we have found that BMI changes are related to activity in neural networks that largely overlap in terms of spatial location and function with networks involved in substance-related disorders. This overlap suggests, that shared biological systems underlie the maintenance of the diseases. These findings can be utilized in therapeutic approaches applied to treat obesity.
