Parkinson’s disease affects about 1 in 100 adults aged 65 and older in the United States, yet the global picture is projected to surge by 2.3 times from 2016 to 2030. Beyond prevalence, the burden shows up in falls, depression, non motor symptoms, diagnosis delays, and the rising Medicare and commercial spending that follows people for years.
Key Takeaways
- 1.0% prevalence (about 1 in 100 people) of Parkinson’s disease among adults 65+ in the United States, based on epidemiologic estimates summarized by the National Institute on Aging
- 2.3 times increase in global Parkinson’s disease cases from 2016 to 2030 is projected by the Parkinson’s Foundation (global cases projection ratio)
- In the Global Burden of Disease 2019, Parkinson’s disease accounted for 0.4 million deaths worldwide
- €2.2 billion direct costs and €11.7 billion indirect costs for Parkinson’s disease in Europe in 2017 (direct vs indirect split)
- $1.0 billion annual cost of Parkinson’s disease in South Korea was estimated in a published economic analysis (country cost estimate)
- $7,000–$10,000 estimated annual incremental healthcare costs per person with Parkinson’s disease in the US (incremental cost range, literature-based)
- The global Parkinson’s disease therapeutics market is projected to grow at a CAGR of 6.2% from 2024 to 2030 (growth rate projection)
- Parkinson’s disease drugs market in the United States reached $2.3 billion in 2022 (US market sales estimate)
- The U.S. market for Parkinson’s disease therapies is projected to reach $3.4 billion by 2031 (forecast)
- ~50% of people with Parkinson’s disease experience motor fluctuations within 5 years after diagnosis (share developing motor fluctuations)
- ~40% of patients with Parkinson’s disease develop dyskinesia after 5–10 years of levodopa therapy (time-based dyskinesia prevalence)
- 6.1 years median time from symptom onset to diagnosis in Parkinson’s disease cohorts (diagnostic delay)
- In a meta-analysis, levodopa improved motor symptoms with a mean UPDRS improvement of about 4–5 points over placebo (quantified)
- In the pivotal trial of safinamide (as adjunct), mean change in UPDRS-DS was improved by ~2 points vs placebo at 24 weeks (trial outcome magnitude)
- In a phase 3 trial of intrajejunal carbidopa/levodopa (DUOPA), OFF time decreased by 4.1 hours in treated patients vs 2.6 hours in control (difference in OFF-time reduction)
About 1 in 100 US adults 65 plus have Parkinson’s, with rising cases, high costs, and lifelong care needs.
