Although dementia has a profound impact in general, young-onset dementia causes additional problems and challenges as people are affected in their prime years. Awareness has increased that people with young-onset dementia and their families have specific care needs and dedicated services are necessary to accommodate those needs. However, in many countries, age-appropriate care and support for people with young-onset dementia is still largely unavailable. In this special article, barriers as well as facilitators for the development of postdiagnostic care and support in young-onset dementia are addressed. Drawing from the experiences in the Netherlands, the establishment of an appropriate infrastructure has proven a corner stone in service development in young-onset dementia. The establishment of a center at the national level for the development and dissemination of knowledge and affiliated regional centers that coordinate and offer care and support at the regional level has helped to reimagine, redefine, but more importantly also rearrange, postdiagnostic care and support in young-onset dementia in the Netherlands. This has resulted in care standards for service provision in young-onset dementia that have been incorporated in the dementia standard at the national level. Also, a quality hallmark has been developed to guide the arrangement of age-appropriate services at the local level. Moreover, specific training programs are in place for health care professionals involved in young-onset dementia. To be able to prioritize topics in research for the upcoming years, a scientific agenda has been established. The strong collaboration between organizations that provide a voice for people with dementia, care providers and research centers, that all strive to support people to live well with young-onset dementia has boosted these developments and may inspire other countries searching for ways to improve postdiagnostic care and support in young-onset dementia.
