Given the age group (mean age of 71), I wonder if it's partly an effect of people with mild cognitive impairment, which the study explicitly mentions are included, being more sedentary (i.e., the effect is backwards or bidirectional). You could also imaging other risks of aging increasing both sedentary time and harming the brain (e.g., social isolation).
Look at the point cloud they're trying to get a fit on!

Yeah, maybe the shrink the brain so small, they cannot have the energy or the capacity to see problems anymore. That's why they are happy....

If that's correlation then yes sitting truely shrinks some people's brains...
