Parkinson Disease (PD) is the second most chronic neurodegenerative disorder in the world, after Alzheimer s Disease (AD), and is estimated to affect about 1% of the population over 60 years of age. PD is caused by the disruption of dopaminergic neurotransmission in the basal ganglia, which causes a reduction in the numbers of dopaminergic neurons in the sub‐ stantia nigra and formation of cytoplasmic inclusions called Lewy bodies [1].
