title: Biological, psychological and clinical markers of caregiver's stress in impaired elderly with dementia and age-related disease.
abstract: Stress refers to the experience, produced through a person-environment transaction, that results in psychological or physiological distress. Everyday stress or hassles have a larger impact on health, in this frame caring for elderly disabled and/or demented persons have been shown to be a chronic role strain. The concept of stress and strain encompasses different levels of individual functioning (physiological, cognitive, affective, social). We studied whether 3 different distressing conditions show (i) different profiles in biological, psychological and clinical indices of stress, and (ii) different response to temporary environmental manipulation. A sample of 29 caregivers of elderly subjects temporarily institutionalized for (i) respite program, (ii) behavioral psychological symptoms of dementia (BPSD) in dementia-control and, (iii) a rehabilitation program after hip fracture, was assessed with clinical, psychological and biological measures. The BPSD appear to be the most powerful distressing factor, both at the beginning and at the end of the study. On the whole, to an improvement of patient's clinical picture, it corresponds only a partial improvement in stress indices of the caregiver. The slope of biological indices don not parallel those of psychological ones. Among psychometric indices, the pattern of recovery differentiate affective and cognitive domains. The "respite" care condition seems to be the less effective in reducing stress in the caregivers. The stress process should be considered in its different domains to allow a tailored intervention.
