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. Thus, caregivers' perceived stress and perceived loneliness may form a symptom cluster that can serve as a marker of risks for physical and mental illness. Due to the overwhelming reliance on family caregivers within the increasing population of individuals with dementia, it is essential that clinicians inquire about caregivers' perceived stress and perceived loneliness, are competent in supporting and educating caregivers, and are knowledgeable about specific resources for caregivers.
