Parkinson's disease ranks among the most common neurologic disorders. The condition's two hallmark neuropathologic findings are the loss of pigmented dopaminergic neurons of the substantia nigra pars compacta and the presence of Lewy bodies and Lewy neurites. More than 6 million people are diagnosed with Parkinson's disease globally. Its incidence and prevalence increase with age, with an average of approximately 60 years. Parkinson's disease is about 1.5 times more common in men than in women, a predilection which may increase with age. In most populations, 3%-5% of Parkinson's disease is linked to known Parkinson's disease genes, representing monogenic Parkinson's disease.
