Cognitive Care Planning Resource

 The Dementia Action Collaborative created this easy-to-digest resource for families, the “Dementia Road Map: A Guide for Family and Care Partners”.  It offers practical information to families as they enter into, live with and navigate the dementia journey.  It is just as useful to clinicians as they strive to support their patients.

The “Dementia Road Map” is available in English and Spanish.  You can view it online or order paper copies at low cost.
