The CAS Content Collection is the largest human-compiled collection of published scientific information. It represents a valuable resource to access and keep up to date on the scientific literature all over the world, across disciplines, including chemistry, biomedical sciences, engineering, materials science, agricultural science, and many more. This allows quantitative analysis of global research publications across various parameters including time, geography, scientific area, medical application, disease, and chemical composition. Currently, there are over 220,000 scientific publications (mainly journal articles and patents) in the CAS Content Collection related to the Parkinson's disease. There has been a steady growth of these documents over the last two decades, with an >30% increase since 2019 (Figure ). The growth rate in the area of PD research is similar to that in the general class of neurodegenerative diseases, with PD growth being faster in the earlier years (2023-2015), but slightly lagging behind recently (Figure ). The scientific journal publications notably dominate (journal/patent ratio ~4-6), but in the recent three years the number of patents exhibited notable growth, correlating with the initial accumulation of scientific knowledge and its subsequent transfer into patentable applications. The United States, China, Japan, South Korea, Germany, France, the United Kingdom, Italy, and Canada, are the leaders with respect to the number of published journal articles and patents related to PD research, with ~1/3 of the patents coming from the United States (Figure ). The journals Movements Disorders, Parkinsonism & Related Disorders, Neurology, and PLoS One have published the highest number of articles related to PD research (Figure ).
