Cerebrospinal fluid mitochondrial DNA reflects body composition and energy metabolism in Parkinson's disease

Key Points

• Cerebrospinal fluid mitochondrial DNA levels correlate with body composition and energy metabolism in Parkinson's disease.
• Higher mitochondrial DNA levels appear linked to better energy metabolism, indicating potential biomarkers.
• Observational analysis reveals significant associations between mitochondrial DNA and body weight in Parkinson's patients.
• Findings suggest mitochondrial DNA may serve as a biological marker for monitoring disease progression in Parkinson's.
