Parkinson's disease is a neurodegenerative disorder marked by motor impairments caused by the damage of dopaminergic neurons in the substantia nigra and the formation of Lewy bodies.
The specific cause of the sickness, however, is unclear. It affects the upper and lower extremities including facial muscles. An increase in the frequency of the disease over the last decade has necessitated greater research to develop advanced diagnostic tests and therapeutic regimens that would provide a lasting cure for Parkinson's disease.
