Medicinal Research Reviews, Volume 40, Issue 6, Page 2650-2681, November 2020., 2020 Abstract Parkinson's disease (PD) is one of the most common neurodegenerative disorders that manifest various motor and nonmotor symptoms. Although currently available therapies can alleviate some of the symptoms, the disease continues to progress, leading eventually to severe motor and cognitive decline and reduced life expectancy.
