A new study out of Colorado State University has found that physical stress in one’s job may be associated with faster brain aging and poorer memory.
Aga Burzynska, an assistant professor in the Department of Human Development and Family Studies, and her research team connected occupational survey responses with brain-imaging data from 99 cognitively normal older adults, age 60 to 79. They found that those who reported high levels of physical stress in their most recent job had smaller volumes in the hippocampus and performed poorer on memory tasks. The hippocampus is the part of the brain that is critical for memory and is affected in both normal aging and in dementia.
A couple of recent research findings are making the media rounds, bringing much needed attention to the high Alzheimer’s rates among Latinos and to preventive approaches based on the Cognitive Reserve — such as, what jobs we choose:
More Alzheimer’s risk for Hispanics, studies find (International Herald Tribune):
- Studies suggest that many Hispanics may have more risk factors for developing dementia than other groups, and a significant number appear to be getting Alzheimer’s earlier. And surveys indicate that Latinos, less likely to see doctors because of financial and language barriers, more often mistake dementia symptoms for normal aging, delaying diagnosis.
- “This is the tip of the iceberg of a huge public health challenge,” said Yanira Cruz, president of the National Hispanic Council on Aging. “We really need to [Read more…] about Alzheimer’s Risk and Prevention: the Cognitive Reserve
