Step 2 (creation of a regional expert centre). In order to offer expert care to PD patients and their carers, a regional Parkinson’s expert centre was initiated. The centre serves as a tertiary referral centre for a large catchment area, by offering critical revision of the diagnosis (if needed supported by ancillary investigations), recommendations with respect to drug treatment and stereotactic neurosurgery, and individually tailored multidisciplinary treatment advice. The centre also initiates and coordinates clinical trials and disseminates the newly acquired knowledge. The centre is part of the neurology department of one of the eight Dutch university medical centres. Several comparable initiatives have meanwhile arisen across the country.
