Aging & Geriatrics

“Our ‘living laboratory’ produces practical findings that are helping seniors delay dementia and other debilitating conditions.”

Research overview

The world’s population is aging, and many U.S. baby boomers are entering their golden years. So it’s only fitting that much research at Kaiser Permanente Washington contributes to helping seniors to lead healthier lives.

“Research on aging cuts across virtually everything our Institute does,” said Eric B. Larson, MD, MPH, the senior investigator who serves as executive director of Kaiser Permanente Washington Health Research Institute (KPWHRI) and Kaiser Permanente Washington vice president for research. This includes studies of older women’s health, mental health issues in the elderly, and controlling cancers and chronic illnesses that become more common with age. The widely cited Chronic Care Model, developed at KPWHRI’s MacColl Center for Health Care Innovation, is now the leading care-design model for everyone, including older people, with chronic disease.

The Institute also hosts several long-running cohort studies, including the Seattle Longitudinal Study, begun in the early 1950s, and the Adult Changes in Thought (ACT) study, a collaboration with the University of Washington. For more than 20 years, ACT researchers, led by Dr. Larson, have focused on finding ways to delay or prevent Alzheimer’s disease, other dementias, and cognitive decline. Through ACT and related studies, the Institute has discovered clues to healthy aging that translate into guidance for safely staying active and avoiding cardiovascular risks. More recently, ACT researchers have also been contributing to research on traumatic brain injury and on the genetic foundations of various diseases, including Alzheimer’s.

In addition, the Institute’s drug safety research contributes to better understanding of how certain common medications affect seniors’ well-being. Meanwhile, our investigators are also seeking ways to help seniors stay physically active, avoid unnecessary hospitalizations, and receive late-life care that best reflects their values and preferences.

“We’re learning what our study participants value as they grow older,” Larson said. “And we hope to apply that to help them have a positive experience with aging—promoting their independence and providing them with skills to cope with any problems that may occur.”
