Relationship of vitamin D deficiency with motor and non- motor functions of Parkinson’s disease

Key Points

• Motor functions significantly decline with vitamin D deficiency, impacting daily activities and quality of life.
• Key evidence shows that low vitamin D levels correlate with worsening motor and non-motor symptoms in Parkinson's patients over time.
• Analysis using clinical assessments and biochemical measures across multiple cohorts indicates strong associations between vitamin D and functional impairment.
• Observational insights highlight the need for further research to determine if vitamin D supplementation could improve patient outcomes.
