Brain fog and headache are also one of the most common symptoms of long covid. Losing consciousness when getting up sounds like POTS[1] and is also common in long covid. Research is showing that people who are asymptomatic during infection can also develop long covid[2].
In general things like brain fog and headache are also symptoms of burnout and probably lots of other things, so I think it would be pretty difficult to clearly distinguish between them. There also isn't a test for it and it won't show up in standard blood tests. And of course it's also possible to have both. Some form of long covid, even if it is just "light" compared to other people who have long covid, could easily push someone who is already on the brink of burnout over the edge.
