Abstract

Background: Prader Willi syndrome is a genetic disorder with a behavioural expression characterized by the presence of obsessive– compulsive phenomena ranging from elaborate obsessive eating behaviour to repetitive skin picking. Obsessive–compulsive disorder (OCD) has been recently associated with abnormal functional coupling between the frontal cortex and basal ganglia. We have tested the potential association of functional connectivity anomalies in basal ganglia circuits with obsessive–compulsive behaviour in patients with Prader Willi syndrome. Methods: We analyzed resting-state functional MRI in adult patients and healthy controls. Whole-brain functional connectivity maps were generated ..
