The Association between DRD3 Ser9Gly Polymorphism and Depression Severity in Parkinson’s Disease

Figure 5

Correlation analysis between ALFF values in the right medial frontal gyrus and anhedonia scores. ALFF values in the right medial frontal gyrus affected by the interaction between groups and genotypes were negatively correlated with anhedonia scores (r = 0.512, ) in the Gly carriers in the PD group. Abbreviations: PD, Parkinson’s disease; ALFF, amplitude of low-frequency fluctuations.
