Among the most successful approaches to helping caregivers is the New York University Caregiver Intervention (NYUCI), designed to support people tending to loved ones with dementia. The program was based on work in the late 1990s by N.Y.U. psychiatric epidemiologist Mary S. Mittelman. A key measure of its efficacy is the fact that caregivers in the program are able to successfully tend to their loved ones at home far longer than nonparticipants, delaying the need for institutionalization. Positive results from NYUCI have now been found in interventions in five states.
