The global prevalence of Parkinson’s disease is expected to more than double by 2050, reaching 25 million cases worldwide, according to new projections. The rise is primarily driven by aging populations and population growth, with developing countries seeing the most significant increases. Researchers from Chinese and Canadian universities published their findings in the BMJ, highlighting the need for urgent action to address the growing healthcare burden.
Projected Rise in Parkinson’s Disease Cases
The number of people living with Parkinson’s disease is projected to increase from 11.9 million in 2021 to 25.2 million by 2050. This 76% rise will result in 267 cases per 100,000 people, posing a substantial challenge for global healthcare systems. East Asia and South Asia will bear the highest burden, with an estimated 10.9 million and 6.8 million cases, respectively.
Key Factors Behind the Rising Numbers
The rapid rise in Parkinson’s disease cases is due to several key factors, including longer life expectancy, aging populations, and changing lifestyles. As countries become more developed, rates of physical activity tend to decline, contributing to the increased risk of neurodegenerative diseases like Parkinson’s. Environmental factors such as air pollution, pesticides, and chemicals also play a significant role in the rising prevalence of Parkinson’s.
Regional Differences and Growing Burden
Sub-Saharan Africa will experience the fastest growth in Parkinson’s disease cases, with a 292% increase by 2050, largely driven by population growth and aging. In contrast, Western Europe will see a 50% rise, while Central and Eastern Europe will face a 28% increase. These differences are linked to factors such as socioeconomic conditions, urbanization, and exposure to environmental pollutants.
The Need for Action: Research and Support
Experts are calling for urgent investments in Parkinson’s research, treatment options, and support systems. David Dexter, research director at Parkinson’s UK, stresses that without significant improvements in healthcare infrastructure and care services, people living with Parkinson’s disease will not receive the support they need.
Preparing for the Future of Parkinson’s Disease
With the expected rise in cases, global healthcare systems must prepare for the growing demand for Parkinson’s care. It is crucial for governments and healthcare providers to invest in early diagnosis, treatment innovations, and better care models to address the global burden of Parkinson’s disease.
