Scientists are making inroads because thousands of people with Parkinson’s and their family members have donated their brains to science, including to PDF-supported programs at Columbia University Medical Center and Rush University Medical Center.

Parkinson's disease may be due to failure of melanin in the Substantia Nigra to produce molecular hydrogen from dissociation of water, to protect the brain from oxidative stress.
PDF's targeted PubMed search provides you with access to journal articles from the last 90 days that may be pertinent to Parkinson's disease research.
Not what you're looking for? Do you need informational publications about Parkinson's targeted for people living with Parkinson's, caregivers and family members?

Melanin, a hybrid electronic/ionic conductor may have the potential to split the water molecule into molecular hydrogen and molecular oxygen. Molecular hydrogen is an antioxidant and may be instrumental in preventing the excessive oxidation leading to Parkinson's disease. Melanin, located in the Substantia Nigra, deteriorates in Parkinson's disease so may be related to the development and progression of the disease, since molecular hydrogen would no longer be generated as it deteriorates. Environmental toxins, thought to be related to development of Parkinson's disease, may cause deterioration of intrinsic melanin, since it is a chelator which would collect such environmental contaminants, but its function of splitting the water molecule into molecular hydrogen and oxygen could be effected as a consequence. Restoring melanin function or providing supplemental molecular hydrogen might be potential treatments for Parkinson's disease.
