Till IL-6 Do Us Part: Elderly caregivers show harmful immune effect

Seniors whose lives revolve around caring for their incapacitated spouses often feel older than their years. It may be more than a feeling, according to a new study.

Over a 6-year period, marital Samaritans caring for a spouse with Alzheimer’s disease or another brain disorder exhibited a dramatic average increase in blood concentrations of a protein involved in immune regulation, concludes a team led by Janice Kiecolt-Glaser and Ronald Glaser, both of Ohio State University in Columbus.
