Chronic Disease Surveillance and Research Branch

The Chronic Disease Surveillance and Research Branch (CDSRB) is committed to serving the public by collecting statewide data about cancer, Parkinson's disease, and chronic disease risk factors; making chronic disease surveillance data available to public health practitioners and qualified researchers; conducting chronic disease surveillance; and communicating surveillance results to the public. In addition, the Branch provides leadership for, and coordination of, California's statewide comprehensive cancer control efforts based on the concept that people and organizations working together to identify problems and develop solutions will lead to better use of limited resources and generation of new resources through new partnerships. CDSRB implements these activities by directing, managing, and monitoring the state-mandated Ken Maddy California Cancer Registry (CCR), California’s Comprehensive Cancer Control Program (CCCP), the Richard Paul Hemann California Parkinson’s Disease Registry (CPDR), the California Behavioral Risk Factor Surveillance System (CBRFSS), and the California Neurodegenerative Disease Registry (CNDR).

Announcements

Alzheimer’s Disease Reporting

Neurodegenerative Disease Data Providers,

California Health and Safety Code (HSC) Section 103871 requires all hospitals, facilities physicians and surgeons, or other health care providers diagnosing or pro viding treatment for a patient with a neurodegenerative disease such as Alzheimer's disease to report each case to the California Neurodegenerative Disease Registry (CNDR) starting July 1, 2025. CNDR has made reporting relatively easy for data providers and have also developed a California Neurodegenerative Disease Registry Guide to Reporting for your reference.

Do You Have Reporting Questions?

Please read the California Neurodegenerative Disease Registry Guide to Reporting to become familiar with how CNDR collects neurodegenerative disease information, the information that is required to report, required to report if available, and the reporting deadlines.

If you are a new neurodegenerative disease data provider and need assistance with updating your system to automatically or manually report neurodegenerative disease information, contact our program at CDSRBhelp@cdph.ca.gov.

If you are interested in additional information about the program please visit and browse the CNDR website.
