No association between striatal dopamine transporter binding and body mass index: A multi-center European study in healthy volunteers
2013
NeuroImage
Preserved Fulltext
In this study, we tested whether BMI and striatal DAT availability are associated. Methods: The study included 123 healthy individuals from a large European multi-center database. ...
Conclusion: The lack of an association between BMI and striatal DAT availability suggests that the regulation of striatal synaptic dopamine levels by DAT plays no or a limited role in the pathophysiology ...
Introduction Overweight and obesity are an increasing health problem worldwide and are defined as a body mass index (BMI) of 25-30 and >30 kg/m 2 , respectively. ...
