- Parkinson's disease often causes nonmotor symptoms such as cognitive decline, memory loss, impaired problem-solving, and depression.
- The PD-CoRE rehabilitation program utilizes structured group sessions to teach practical problem-solving strategies and coping mechanisms.
- Participants showed significant improvements in global cognition and practical judgment, and a reduction in depression severity after the intervention.
A rehabilitation program called PD-CoRE was shown to help adults with Parkinson’s disease improve their cognitive function and lessen symptoms of depression in a recent study.
The program uses group sessions to teach practical problem-solving strategies, giving participants tools to manage the daily cognitive challenges that often accompany the neurodegenerative condition.
“PD-CoRE appears to be a promising intervention for enhancing cognitive functioning and aspects of well-being in individuals with [Parkinson’s],” researchers wrote, calling for more studies to further validate and refine the program.
The study, “Parkinson’s disease cognitive rehabilitation of executive functioning (PD-CoRE): A community-based intervention study,” was published in Parkinsonism and Related Disorders.
