Fatigue among elders in caregiving and noncaregiving roles.

Fatigue is a complex symptom prevalent in informal caregiving. When role demands exceed caregiver resources, fatigue ensues and caregiving can be compromised. The purpose of this study was to compare perceptions of fatigue among older adults (N = 92) caring for spouses with Alzheimer's disease, Parkinson's disease, or cancer with a control group of older adults (N = 33) whose spouses required no extra care. Caregiving elders reported more fatigue, less energy, and more sleep difficulty than did control participants. All caregiving groups reported similar levels of fatigue, energy, sleep, and self-reported health even though there were marked differences regarding spousal status. Health care providers can support older caregivers in monitoring their own health and in recognizing the need for services that support the caregiving role.
