Calcium, Magnesium and Aluminum Concentrations in Parkinson's Disease - 1992.
Mg concentration was lower in cortex, white matter, basal ganglia and brain stem of PD brains compared to control brains (p < 0.01). Al concentration in the substantia nigra, caudate nucleus and globus pallidus was higher in PD brains compared to controls (p < 0.05) and significantly higher in gray matter and the basal ganglia (p < 0.01). These studies are consistent with other observations linking high concentrations of Al and low levels of Mg in the pathogenesis of CNS degeneration and PD.
