Brief Title  An fMRI Study of Self-Regulation in Adolescents With Bulimia Nervosa
Official Title  An fMRI Study of Self-Regulation in Adolescents With Bulimia Nervosa
Brief Summary

The aim of this project is to use both functional MRI (fMRI) and behavioral measures to investigate how disturbances in frontostriatal neural systems contribute to the impulsive and habitual binge-eating behaviors in patients with Bulimia Nervosa (BN). Findings from this study will have wide-ranging importance for our understanding of the development and treatment of BN.

Detailed Description

Patients with Bulimia Nervosa (BN) have difficulty regulating impulsive behaviors as suggested by their binge-eating and purging, as well as the high incidence of drug abuse and shoplifting in this population. Understanding dysfunction in the frontostriatal circuitry that mediates self-regulatory control processes will aid development of new therapeutics for the impulsivity associated with BN. Thus we aim to use fMRI and neuropsychological measures to investigate the functioning of frontostriatal systems and self-regulatory control processes in adolescents with BN.

Participation in this study includes 4 sections: Neuropsychological Tests, Diagnostic interviews, Pregnancy Test, and MRI scan. All efforts are made to coordinate procedures into one day, and they require between 4 and 5 hours of the participant's time. The option of splitting participation into two study days is also offered for participants who find it more convenient. Participants are compensated with $100 in the form of a check, which is mailed to their home address.
