(Press-News.org) Even though aging is the largest risk factor for Parkinson’s disease, the majority of research aimed at taming the incurable neurodegenerative motor disease has largely left aging out of the mix. A group of researchers from around the globe seek to change that. “Unraveling the intersection of aging and Parkinson’s disease: a collaborative road map for advancing research models,” is now available online at the Nature publication npj Parkinson’s Disease.
The vast majority of the Parkinson’s research done in the lab of Buck professor Juie Andersen, PhD does involve looking at the disease through the lens of aging. Andersen is one of the senior authors of the paper. “Many age-related changes in the brain mirror those seen in the early stages of Parkinson’s,” she said, noting that many of the whole-body hallmarks of aging, including mitochondrial dysfunction, impaired autophagy, increased inflammation and cellular senescence have been shown to contribute to the disease. “The research community needs to approach this disease holistically and aging is the place to start. Aging biology is emerging as a therapeutic target.” Minna Schmidt, PhD, a postdoctoral fellow in the Andersen lab was first author of the paper.
An estimated 1 million Americans have Parkinson’s; globally the estimate exceeds 10 million, with numbers on the rise as aging populations increase in developed countries. Researchers make the case for the focus on aging by pointing out that only 10 percent of cases are based on family history. Most Parkinson’s is sporadic, arising spontaneously from a mix of factors including age, genetic vulnerability, environmental exposures and poor lifestyle choices. “When we reviewed studies that include aging we concluded that the influence of aging on Parkinson’s is subtle, emerges gradually and likely interacts synergistically with other contributing factors,” says Andersen.
Andersen and her colleagues came up with a comprehensive roadmap that identifies mouse models that are best utilized for preclinical experiments that incorporate aging as a central element of Parkinson’s disease pathogenesis. The roadmap also aims to standardize methodologies, foster cooperation and optimize resource utilization. “As a group we recognize that the complexity and diversity of Parkinson’s models, combined with the lengthy nature of aging studies, present challenges that require substantial resources and innovative approaches,” says Andersen. “Our work is aimed at making it easier for researchers to include aging as a critical element of their efforts to tackle this disease.”
This paper is part of a larger effort from a 4-year consortium funded by the Michael J. Fox Foundation. In addition to this work which involves guidelines for mouse models, other papers focus on the use of human cell cultures and primates in Parkinson’s research.

About the Buck Institute for Research on Aging
At the Buck, we aim to end the threat of age-related diseases for this and future generations. We bring together the most capable and passionate scientists from a broad range of disciplines to study mechanisms of aging and to identify therapeutics that slow down aging. Our goal is to increase human health span, or the healthy years of life. Located just north of San Francisco, we are globally recognized as the pioneer and leader in efforts to target aging, the number one risk factor for serious diseases including Alzheimer’s, Parkinson’s, cancer, macular degeneration, heart disease, and diabetes. The Buck wants to help people live better longer. Our success will ultimately change healthcare. Learn more at: https://buckinstitute.org

Researchers at the University of California San Diego and the Veterans Affairs San Diego Healthcare System have identified a distinct biological pattern of chronic rhinosinusitis (CRS), a chronic respiratory illness frequently associated with exposure to airborne toxins, such as wildfire smoke and military burn pits. The research team, led by first author and UC San Diego Assistant Professor of Medicine Xinyu "Steve" Wang, MD, PhD, found that veterans with CRS who were exposed to burn pits and other toxins show a marked increase in sinus ...

When severe weather strikes, the National Weather Service’s (NWS) Office of Water Prediction (OWP) makes critical flood forecasts with the National Water Model. Despite improvements over time, the model’s performance has plateaued in recent years, leaving researchers from the federal government, academia, and private industry searching for a better solution.
Now a new set of software tools, the Next Generation Water Resources Modeling framework, or NextGen, will help develop better predictions. As detailed in a new study led by OWP and the University ...
ANN ARBOR—A University of Michigan study has taken a fine-grained, long-term look at residential-area air pollution and how it relates to deteriorating mobility—and hindered recovery—for older Americans.
By pairing and comparing the mobility and disability experiences of 29,790 participants in the national Health and Retirement Study with air quality exposures over 10 years, a team of veteran environmental health researchers found that people with long-term exposures were at greater risk of progressing from no physical function limitations to states of more physical function limitations ...

New research shows that people who engage in lifelong learning such as reading, writing and learning languages have a lower risk of Alzheimer’s disease and slower cognitive decline.
The study does not prove that lifelong learning decreases the risk of Alzheimer’s; it only shows an association.
The study looked at 1,939 adults, examining cognitive enrichment including access to atlases and newspapers as children and having library cards in middle age.

Higher self-reported levels of resilience were linked to lower anxiety and depression and better coping strategies during the COVID-19 pandemic, according to a study published February 11, 2026, in the open-access journal PLOS One by Joseph Anthony Pettit of Bangor University, U.K., and colleagues.
Successfully managing and adapting to life’s challenges often requires resilience. Resilience has been linked to coping better with mental ill-health, lower emotional distress following adversity, and faster recovery from such experiences. However, past research has neglected individual profiles of resilience and ...
A male fruit fly in a laboratory chamber extends his wings and vibrates them to produce his species' version of a love song. A female fly stays nearby listening. Suddenly, a green light flashes across the chamber for a fraction of a second. The male's song cuts off mid-note and his wings fold. The female, not impressed by the interrupted serenade, walks away. The culprit? An AI system that watched the male begin his courtship dance and shut down his song-producing brain cells.
