Parkinson's Disease Research Registry; establish within State Department of Health.

HB 999 establishes the Mississippi Parkinson's Disease Research Registry within the State Department of Health to track the incidence and prevalence of Parkinson's disease and related conditions (Parkinsonisms) across the state. It requires movement disorder centers and certified healthcare providers treating these conditions to submit patient data to the registry starting January 1, 2027, with patients able to opt out of data collection. The registry will collect epidemiological data while keeping all information confidential, and the Department must make anonymized data available to approved researchers. The bill also mandates public website updates, annual reports to health committees, and requires the State Health Officer to appoint an advisory committee with patient and medical expertise to guide the registry.
