ONEgeneration Adult Daycare is both a medical and social model that helps seniors and adults with an intellectual and developmental disability (I/DD) to continue living at home with their loved ones by providing a safe, supervised haven during the day. ONEgeneration Adult Daycare provides participants with person centered, cognitively stimulating activities, socialization, and physical exercise, to participants with Dementia, Alzheimer’s disease, Parkinson’s disease and adults with I/DD and dementia, while simultaneously providing respite to their caregivers. The hallmark of ONEgeneration is their intergenerational programming which unites seniors and children for daily multicultural activities. Research has shown that young children who participated in intergenerational care had more advanced motor and cognitive skills, higher developmental scores, and more advanced social and emotional competencies than their non-intergenerational peers did, and older adult participants reported lower levels of loneliness, reduced agitation, and improved health.
