For every unit of decline in brain volume, individuals in their 40s and 50s with low listener availability had a cognitive age that was four years older than those with high listener availability. Too often we think about how to protect our brain health when we're much older after we've already lost a lot of time decades before to build and sustain brain-healthy habits," says Salinas. Taking that simple action sets the process in motion for you to ultimately have better odds of long-term brain health and the best quality of life you can have." Study participants' cognitive resilience was measured as the relative effect of total cerebral brain volume on global cognition, using MRI scans and neuropsychological assessments taken as part of the FHS. Researchers note that further study of individual social interactions may improve understanding of the biological mechanisms that link psychosocial factors to brain health.
