Objectives The pathophysiology of depression and anxiety in Parkinson's disease remains obscure. We aimed to compare the fractional anisotropy (FA) values of Parkinson's disease (PD) patients with and without depression to investigate the nature of depression in PD. Methods Twenty-eight patients were divided into two groups: those with depression and those without. Diagnosis of depression was made using the DSM-IV criteria. Patients in the two groups were matched for Hoehn Yahr stage. Results There were significant reductions in FA values in the bilateral frontal ROIs possibly representing anterior cingulate bundles. Conclusions The anterior cingulate bundles play an important role in depression in PD, and some aspects of depression in PD have pathological processes in common with de novo depression.
