New models of care seek to reorganize healthcare to meet the challenges of a growing number of persons with chronic conditions, to optimize the use of the available workforce, and to improve the quality of care. Increasingly, these models also seek to organize care in a manner that addresses cost and efficiency in addition to quality of care. This chapter first revisits the history of chronic care models and then provides a description of successful and sustainable examples of integrated, multidisciplinary approaches for persons with dementia, persons with Parkinson's disease, and the frail elderly. We focus on models for neurodegenerative diseases and draw from the perspectives of research, clinical practice, and informal caregiving. Although focused on neurodegenerative disease, the principles of these approaches reflect the hallmarks of good primary, geriatric, and collaborative care. Many of the current models of care emanate from a medical approach led by physicians and other professional providers within the formal healthcare setting. Innovative approaches, however, now seek to incorporate these medical models within social and community services. We conclude this chapter by describing several international examples of community-based efforts that have been implemented to improve the care and lives of patients with dementia and their informal caregivers, which is at present one of the top priorities in many countries., (Copyright © 2019 Elsevier B.V.
