Chronic stress can steal years from caregivers' lifetimes

COLUMBUS , Ohio The chronic stress that spouses and children develop while caring for Alzheimer's disease patients may shorten the caregivers' lives by as much as four to eight years, a new study suggests. The research also provides concrete evidence that the effects of chronic stress can be ...
