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.
Super-Agers Show Resistance to Tau and Amyloid Accumulation, Maintain High Cognitive Function (Society of Nuclear Medicine and Molecular Imaging press release):
Super-agers, or individuals whose cognitive skills are above the norm even at an advanced age, have been found to have increased resistance to tau and amyloid proteins, according to research presented at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2020 Annual Meeting. An analysis of positron emission tomography (PET) scans has shown that compared to normal-agers and those with mild cognitive impairment, super-agers have a lower burden of tau and amyloid pathology associated with neurodegeneration, which probably allows them to maintain their cognitive performance. An image showing the comparison of tau and amyloid distribution patterns in these different cognitive aging trajectories has been selected as SNMMI’s 2020 Image of the Year.
