Day programs provide activities for seniors and may also offer meals, social/recreational outings and general supervision. Adult daycare centers operate under a social model and/or a health care model. Daycare centers may focus on providing care only for persons with Alzheimer’s and related dementia or their services may be available for any disabled adult. Some daycare centers may maintain an on-site nurse. The social stimulation and recreational activities provided may improve or maintain physical and cognitive function. For caregivers, adult day care centers provide respite care, enabling caregivers to work or to have a break from their caregiving responsibilities.
