It’s one of the only studies where we can not only track people over their lifetimes, but also have brain scans, which allows us to look at the relationship between aging and brain health. AdvertisementYou found that people with persistent financial hardship are more likely to have cognitive decline in their 50s and worse brain health as they progress into their 70s and beyond. What you can think about with your brain isn’t the same when you struggle versus when you don’t struggle. We know that financial deprivation and poverty are linked to social isolation, and social isolation is linked to cognitive decline. So we would like to better understand how these different variables interact and accumulate over the lifespan, and understand the mechanism for how financial instability explains brain health.
