Higher bilirubin levels in early stages of Parkinson’s disease

Takeaway

  • Increased serum bilirubin levels were observed in those with Parkinson’s disease (PD), notably in early stages of the disease.

Why this matters

  • Analysis of oxidative enzyme heme oxygenase 1 (HO-1), which is involved in bilirubin production, may provide further insights in PD pathology.
