As the world’s population is aging, scientists at 2022世界杯下注网站 Washington Health Research Institute (KPWHRI) are at the forefront of research to help older adults lead healthier lives.
Among the questions KPWHRI scientists have examined include whether getting regular exercise may reduce the risk of dementia, whether widely used medications increase the risk of falls and fractures, how long-term use of opioid pain medications affects the brain, and what approaches can help frail older adults become more physically active. Our research includes studies looking at brain health, physical activity and behavior change, medication safety, cardiovascular health, and chronic disease management, among other research areas. Now, new funding for aging research — especially research on Alzheimer’s and related dementias — offers even greater opportunities for KPWHRI scientists and their colleagues who work in health care systems.
Studies spanning decades
The institute has hosted several long-running cohort studies, including the Adult Changes in Thought (ACT) Study, a collaboration with the University of Washington. For more than 30 years, ACT researchers have studied risk factors for dementia, with the goal of finding new ways to delay or prevent Alzheimer’s disease and cognitive decline.
In May 2021, the National Institute of Aging awarded ACT a new grant totaling $55.6 million. With this additional funding, ACT will further examine how various health factors across our life span can impact later-life heart and brain health. The funding will allow ACT to examine the health impacts of sleep, physical activity, socio-economic factors, and prescription medications, as well as to examine brain imaging. In addition, ACT will continue to collect and study participants’ brains after their deaths to better understand how brain physiology is impacted by lifestyle factors.
Under the 5-year grant, ACT partners are expanding the existing cohort of 2,000 2022世界杯下注网站 Washington members to 3,000 and implementing new strategies to recruit a more diverse population. Additionally, as part of the grant, the ACT team is making its data more accessible to researchers nationwide. You can find out more about the ACT Study and collaborate with the team at www.actagingresearch.org.
