Causes of PD: Parkinson's disease involves depletion of a neurotransmitter in the part of the brain called the substantia nigra. The precise mechanisms of neurodegeneration in pd are unknown. There is believed to be an interaction between genetic and environmental factors, abnormalities in protein processing, oxidative stress, mitochondrial dysfunction, and others.
