California Neurodegenerative Disease Registry (CNDR)
California Neurodegenerative Disease Registry (CNDR) is California's statewide population-based neurodegenerative disease surveillance system. In 2021, California enacted
Health and Safety Code (HSC) section 103871 which requires the CDPH to collect other neurodegenerative disease information (other than information on Parkinson's disease, for which the CDPH began collecting information in 2018). CDPH will use the data collected by CNDR to determine incidence and prevalence of other neurodegenerative diseases such as Alzheimer's disease, multiple sclerosis (MS), Huntington's disease, and amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease in California. HSC also gives the director the authority to determine which other neurodegenerative diseases will be collected and when collection begins.
HSC 103871 also requires a hospital, facility, physician and surgeon, and other health care providers to report each case of neurodegenerative disease to CDPH.
In 2023, CNDR started collecting MS information. CNDR is a valuable public health resource and data from the registry may be used to advance our understanding about neurodegenerative disease in California and its impact. CNDR data will be accessible to qualified researchers with valid scientific approval to perform neurodegenerative disease research.
CNDR has quarterly data submission deadlines. Please see the table below. If you have a question(s) about how to submit your neurodegenerative disease information to CNDR, please contact us at
