1.2 million patients by 2030
Reached for comment, James Beck, PhD, chief scientific officer for the Parkinson’s Foundation, said these findings are not surprising. “They are aligned with the work the Parkinson’s Foundation has done to show that the number of people with Parkinson’s disease has increased over time. We are working on an improved estimate of Parkinson’s disease incidence and predict that Parkinson’s disease will continue to rise as the population ages, so an increase in mortality rates would be expected,” Dr. Beck said.
He noted that much of the public health statistics regarding Parkinson’s disease are outdated and that the Parkinson’s Foundation has been partnering with others to update them.
“For instance, to calculate an accurate estimate of the prevalence of Parkinson’s disease, the Parkinson’s Foundation Prevalence Project was formed. The findings from this group demonstrated that the number of people living with Parkinson’s disease will rise to nearly 1.2 million by 2030, a substantial increase from the estimate of 930,000 for 2020,” Dr. Beck said.
“The overarching message is that more people are being diagnosed with Parkinson’s disease, not that more people are dying from the disease,” he added.
“Over the last 20 years, our understanding of Parkinson’s disease has changed and developed, so clinicians are more aware and better able to properly diagnose Parkinson’s disease. This could mean that the cause is likely due to an increase in diagnosis rates and better recognition of Parkinson’s disease, which would lead to higher rates of identifying Parkinson’s disease as a cause of death,” said Dr. Beck.
The study had no targeted funding. Dr. Bao and Dr. Beck have indicated no relevant financial relationships.
