family systems

Background: The biopsychosocial model has been applied through collaborative care dementia models to the diagnosis, symptom management, and treatment of dementia with a focus specifically on the person with dementia. Because individuals with dementia are increasingly dependent upon others particularly as the illness advances, dementia care requires the involvement and commitment of others, usually family, along with support from community-based resources.

Comprehensive improvements in medical care, technology and residential settings have resulted in persons with developmental disabilities (DD) advancing to older age and outliving parental caregivers (Heller & Arnold, 2010). Typical siblings are expected to become the primary caregiver to their sibling with DD when parents become ill or die and unable to provide care (Burke, Fish, & Lawton, 2015; Heller & Arnold, 2010).
