About Parkinson’s
Global Burden
Globally, PD affects more than 10 million individuals, with approximately 1.6 million reported cases in India alone. The burden of PD will increase significantly with a rising global population aged 60+.
By 2025, it is projected that over 25 million people worldwide will be living with Parkinson’s disease, with cases rising fastest in aging populations like the US, Japan, and parts of Europe.

1 in 100 over the age of 60 is diagnosed with Parkinson’s disease. Increase in aging population =leads to rising number of cases
Indian Burden
In India, the prevalence of PD is on the rise, making it crucial to spread awareness and understanding of the disease. Moreover, early diagnosis and care can substantially enhance the quality of life of affected individuals.
The recent improvements in the healthcare sector have resulted in a remarkable increase in life expectancy and a proportional increase in PD cases in India. This trend is expected to continue in the coming decades.
It is estimated that 10–15 lakh people in India suffer from Parkinson’s disease, with higher rates observed in older populations, and by 2050, there will be approximately 23 lakh people suffereing from Parkinson’s.

Parkinson’s disease will impact more people as India’s population ages. Some demographic factors influencing PD are:
Demographic Age Factors
The incidence rate of Parkinson's disease in India is estimated to be 4 to 20 per 100,000 people annually. The incidence is more likely in adults over the age of 60, while early-onset Parkinson's might develop in people under 50.
Gender Distribution
Studies suggest that Parkinson's disease may be slightly more common in men than women in India, though the reasons for this disparity are not fully understood.
Geographic Variation
Parkinson's disease appears to be more common in southern India compared to northern regions. This variation may be influenced by genetic, environmental, and lifestyle factors, with significant variations between urban and rural areas
Incidences in Rural Settings
Pesticide exposure is a well-established environmental risk factor for Parkinson’s disease, with studies showing that individuals exposed to certain pesticides have up to a 70% higher risk of developing PD. In India over 65% of the population resides in rural areas and pesticide use is widespread.
