Its worth a read. All the usual medical gaslighting because the poor boy was seeing demons and monsters and such, got multiple psychiatric diagnoses, lots of hard drugs to control that didn't do anything but it came alongside some physical symptoms too and the MRI when the dad reviewed it even showed signs of an infection. After wasting 100s of thousands and institutionalising their son and him only getting worse they went to a functional medicine place that actually tested him for infections, he had stretch marks which were red angry suggestive of Bartonella henselae bacterial infection and sure enough treatment for that did result in him recovering completely.
So like we are used to medicine couldn't be bothered to investigate, slapped on some psychiatric diagnoses and just left the kid to rot because nothing helped at all and that didn't bother a single one of his physicians whatsoever.
The author of the times article here has the much more common Lyme and led with the physical symptoms and even that required him to diagnose himself. The author is big on talking about the fringe of Mystery illnesses. But where we don't exhaust the primary possibilities of diagnostics, and pursue the oddities where they lead, they aren't really mysteries in the way this guy is describing, they are examples of medical negligence. Bacterial infections are pretty common, hallucinations absolutely possible since many drop neurotoxins and the tests are widely available to find evidence of an infection and its then about which one. Lyme, Bartonella henselae and the recent Strep A infections are all fairly common and a basic immune system check will show something is up and then its about digging to identify what. I know from my own experience the doctor saw immune function like I was fighting something, still true 10 years later but they have never bothered to look at what.
Something Long Covid sufferers have recently been recommending is to get the actual results yourself. Don't accept the doctors "all is well", because in a lot of cases there are things wrong on the blood tests/MRIs and they just aren't being told. Again nothing mysterious about the illness, just more medical negligence and gaslighting.
