The individuals with PD were also compared to matched non-PD controls (n=64).Results: PD participants with low executive function reported significantly higher pain interference (p< 0.05), despite reporting similar pain severity levels compared to other phenotypes. These differences remained statistically significant, even after accounting for important confounders such as anxiety and depression (p< 0.05).Discussion: Pain interference in those with lower executive function may represent a target for psychosocial interventions for individuals with pain and PD.Keywords: Parkinson’s disease, pain, cognitive function, profiles, phenotypes
