This research studied the quality of life of informal caregivers of aging and elderly adults with Down syndrome. Prior research indicates some degree of deteriorating Quality of Life (QoL) for caregivers, however, there is no empirical research isolating the aspect QoL affected. This study seeks to research the following two questions: 1) What are the trends in the four domains that influence Quality of Life, both positively and negatively, of informal caregivers of aging and elderly adults with Down syndrome? and 2)What supports do caregivers of aging and elderly adults with Down syndrome want to improve their own Quality of Life? The methodology is a Qualtrics questionnaire administering the WHOQOL-BREF to caregivers of the aging (30-39 years old) and elderly (40+ years old) individuals with Down syndrome. The results showed that informal caregivers caring for elderly adults with Down syndrome lowest Quality of Life domain was social and highest Quality of Life domain was physical. Informal caregivers caring for aging adults with Down syndrome lowest Quality of Life domain was physical and highest Quality of Life domain was environmental.

The high susceptibility to infection in persons with Down Syndrome (DS) has led some investigators to explore the possibility of a defect in the immune system. Studies to date indicate no defect in humoral immunity suggesting that the defect might be in the cellular immune functions, but no specific defect has been found. Our investigation of the cellular immune system of adult DS patients was conducted by examining (1) the number and function of T-lymphocytes, (2) the phagocytic function of granulocytes, (3) the level of superoxide dismutase-1 (SOD-1) in leukocytes, and (4) the effects of SOD-1 on lymphocyte and granulocyte functions.
