Parkinson disease (PD) affects people of all races and ethnicity worldwide. PD is a multineurotransmitter and multisystem disorder and our current concept of the natural history of PD has changed considerably over the past decades. ⋯ Several factors might play a role in the influence of ethnicity on PD, such as pharmacogenetics, sociocultural aspects and environmental exposures. Increased knowledge on the role of ethnicity in PD may help shed light on the symptom expression and treatment response of PD, address inequalities in health care delivery worldwide and improve the delivery of personalised medicine.
