Hmmm, thanks, but that research doesn’t seem to make any effort to distinguish people with diagnosable dementia conditions from those without, and does mention that the rates can be quite different for different people, so I can’t tell whether there’s anything about it which contradicts what I thought I remembered encountering in other research.
You can look at the UK study directly: paper. They explicitly mention that they are interested in “normative (i.e. non-pathological) age-related differences in cognition” and that they took pains to get a representative sample.
If you accept that their sample is representative, it does show major cognitive decline with age regardless of who got diagnosed with what. That decline is not subtle.
