The headline quite specifically does say: "Uncovering the Molecular Basis of Long COVID Brain Fog"
The article also implies that AMPA drugs could address COVID brain fog:
> For example, drugs that suppress AMPAR activity could be a viable approach to mitigate brain fog.
This was one of the points I was trying to counter.
It also claims to have "resolved key uncertainties":
> In summary, the team’s findings resolve key uncertainties about the biological basis of Long COVID brain fog
Which is obviously not true. This is only one biomarker, not the resolution to a key uncertainty.
I disagree that I'm reading too much into it. These are direct quotes from the article I was responding to.
