Parkinson's disease in South Asians
From Wikipedia, the free encyclopedia
Epidemiological studies have shown lower age-related prevalence of Parkinson's disease in South Asians, with the rate of prevalence being around 52.7 per 100,000 as compared to a higher prevalence rate observed in populations with European origin, 108-257 per 100,000. Additionally, several studies have seen a higher prevalence of in women which contrasts with global data that observes a overall higher prevalence seen in men. Compared to most of the rest of the world, the South Asian countries (including India, Pakistan, Nepal, Bhutan, Maldives, Afghanistan, Sri Lanka, and Bangladesh) seem to be on the lower end of PD prevalence. However, this is not to say that PD is not of concern in these countries. Over the past couple of years, the rate of Parkinson's has gone up in South Asia meaning that it is of high importance to study this pathological disease in these populations.[1]
