Parkinson’s disease is a progressive neurodegenerative disorder which results in depletion of dopamine within the substantia nigra pars compacta in the central nervous system. Parkinson’s disease primarily affects the motor system causing the classical symptoms of bradykinesia, tremor and rigidity.

In addition, Parkinson’s disease results in non-motor symptoms such as depression and dementia which can worsen over time.

The exact cause of Parkinson’s disease is unknown and there are no disease-modifying treatments.
