Johns Hopkins researchers work to give elderly a better quality of life

Johns Hopkins University has assembled a group of experts based at its Bayview Medical Center in Baltimore to accelerate work underway to better understand what’s causing these age-related problems, slow them or even fix them.

Much of the research builds on decades of work at Hopkins and elsewhere. Some efforts now under the aging project banner already are in advanced stages. Devices and therapies ready to head to human trials can seek volunteers among a large pool of Hopkins geriatric patients.There is urgency to the effort. More than 54 million Americans are age 65 or older, or about 16 percent of the population, federal statistics show.

Bhattacharyya said the NIA was looking to the centers to develop devices and therapies that would specifically help older adults live independently at home. That means, for example, pursuing technology to help with decision-making, coordinating care among doctors, or supporting cognitive therapy. Joshua Blair, a master’s student in engineering, is gearing up to test a device to promote better sleep and memory retention, a common problem among older adults, particularly those with dementia or other cognitive impairments.

On a recent day, Nick Milcik, a research specialist in the Hopkins geriatrics department, was handling some cortisol samples taken from the saliva of surgical patients over time. Researchers are hoping to see whether levels of the stress hormone eventually can help predict, for example, who will do well after surgery for knee replacement. That could tell doctors when they can go ahead and when they should delay or cancel procedures in patients unlikely to benefit.
