Older Chinese Americans who bottle up their emotions and internalize stress may face a sharp decline in memory and cognitive function, according to new research from Rutgers Health that fills a significant gap in brain aging science.
The findings, published in The Journal of Prevention of Alzheimer's Disease, tracked over 1,500 Chinese American participants in the Chicago area between 2011 and 2017. Researchers measured three behavioral factors: how people handle stress internally, their connection to their community, and their ability to seek help or talk through problems. Only one stood out as a clear threat to memory: internalized stress.
Internalized stress includes feelings of hopelessness and the habit of absorbing difficult experiences quietly rather than expressing or resolving them. Across three separate measurement periods in the study, this pattern showed a strong link to memory loss.
Michelle Chen, lead author and assistant professor of neurology at Rutgers Robert Wood Johnson Medical School, emphasized that these findings matter because stress and emotional struggles often go unnoticed in aging populations, yet they shape how the brain ages over time.
The research also highlights how cultural pressures and structural barriers compound the problem. Older Chinese immigrants often face language obstacles, cultural disconnection, and the weight of the model minority stereotype, which portrays Asian Americans as uniformly successful and healthy. That narrative can mask real emotional distress and make older adults less likely to seek support.
What makes this research significant is not just the problem it identifies, but the possibility of action. Unlike many risk factors for memory loss, internalized stress is modifiable. The researchers say the next step is developing culturally sensitive interventions designed to help older adults process emotions, reduce hopelessness, and protect cognitive health.
Chen noted that because Asian Americans have been largely underrepresented in brain aging research, gaps remain in understanding how memory decline develops across different populations. With the number of older Asian Americans growing rapidly, understanding their specific risk factors is both urgent and overdue.
The study was supported by the Rutgers-NYU Resource Center for Alzheimer's and Dementia Research in Asian and Pacific Americans.
