Early symptoms of PD are primarily due to the selective degeneration of dopaminergic neurons of the substantia nigra, innervating the neostriatum. The primary cause of PD is unknown, however, mitochondrial failure, oxidative stress and genetic factors, responsible for neurodegeneration in the substantia nigra are investigated hypotheses for the etio… Show more
