Caregivers of individuals with dementia are at risk for chronic stress and social isolation. These exogenous factors may lead to perceived stress and perceived loneliness—psychosocial endogenous (subjective) elements of caregiving experience. Chronic stress and perceived loneliness may disrupt neuroendocrine and neuroimmunological regulation, creating low-grade systemic inflammation, promoting proinflammatory gene expression, and expediting cellular aging (endogenous physiological factors). These disturbances may enhance caregivers' risk for chronic conditions of inflammatory pathogenesis.
