Brain iron, along with dopamine, "causes oxidative stress, inflammation, and neurodegeneration," Dr Franthal explained. "Past studies have proved there is a significantly higher iron deposition in substantia nigra in Parkinson's compared to healthy controls." So for the current study, "our objective was to investigate longitudinal changes in nigral iron concentration in PD compared with other tremor syndromes."
