Associations Among Pain, Depression, Cognition, and Motor Function in Parkinson’s Disease

Key Points

• The aim is to examine the relationships between pain, depression, cognition, and motor function in Parkinson’s Disease (PD).
• Analyzed associations between motor and nonmotor symptoms in PD.
• Focused on the PIGD (postural instability-gait disturbance) subtype.
• Evaluated depression and cognition among PD patients.
• Motor dysfunction showed a significant association with depressive symptoms and cognitive performance.
• Pain did not have a notable impact on cognitive function.
• Findings emphasize the importance of assessing both motor and nonmotor symptoms in PD.
