In the Netherlands a rapidly increasing number of multidisciplinary memory clinics (MMC) currently diagnose 25% of the patients with dementia. Following the diagnostic work-up, MMCs are increasingly involved in post-diagnosis treatment and coordination of care, which probably is very important for patients and caregivers, but also very time consuming and expensive. This study will focus on the important question whether this complex post-diagnosis treatment and care coordination, evaluated both on effectiveness and costs, should be carried out by MMCs (intervention) or by General Practitioners (GPs) (control) as pivot of delivery of health care for these patients.
