Patients were given a questionnaire to gather data about their medical and living statuses. To assess cognitive assessment, SCOPA-COG (Scales for Outcome in Parkinson Cognition) was used by an expert cognitive neuroscientist. Results:The age inversely correlated to memory and learning (P < 0.01). Education level correlated directly to attention, memory, learning, executive function and visuospatial function (for all items P < 0.001). Spouse relationship type showed inverse association with memory, learning, executive function and visuospatial function (P < 0.05). Conclusion:Cognitive domains in PD patients may be under the influence of different factors. Due to the lack of control group in this study, cautious interpretation of findings is needed. https://ijnl.tums.ac.ir/index.php/ijnl/article/view/775 https://ijnl.tums.ac.ir/index.php/ijnl/article/download/775/48
