The lack of conceptual clarity on social health in de- mentia research hinders its articulation. we aim to apply concept advancement for social health to provide con- ceptual clarity by building from a conceptual meaning to domains. the procedure is underpinned by theoretical models and epidemiological evidence on the relation be- tween social heath and cognitive functioning.this led to considering social health as a reciprocal relational concept that refers to the influence that an individual has on others (social environment), and vice versa. we distinguished three domains defining the individual level, representing the social competences of the individual, and three do- mains defining the social environmental level (structure , function and appraisal of the relationship. we hypothesize that social health acts as a driver for stimulating the use of cognitive reserve. this conceptual advancement promotes developments that integrate neurobiological and social sciences and new interventions to support older people with and without dementia. convoys of care toni antonucci , and kristine ajrouch , 1. university of michigan, ann arbor, michigan, united states, 2. eastern michigan university, ypsilnati, michigan, united states many existing alzheimer’s disease (ad) caregiving
