Following a surgical procedure for heart problem, which was relatively easy for current medicine, it's as if his brain didn't come back, his personality changed, he was losing the ability to be himself.
Horrible, but real.
Also today I sat with a close family member as they received a diagnosis for a serious psychiatric illness. Treatable, but the drugs currently available have rough side effects. It's not going to get easier.
The article characterizes Halloway's disease as a "rare" disorder, only one in 5,000 people.
But it really seems as if the bigger picture, of everyone currently sidelined with "Long COVID" or chronic mental health conditions or both... Well, it's less rare than I might like it to be.
From the article it seems the problem manifested years before the surgery. The surgery only accelerated the decline.
About Lee Holloway of Cloudflare.
Vitamin B12 deficiency can disrupt sleep patterns, can cause symptoms consistent with FTD (including brain atrophy), and the use of nitrous oxide in general anesthesia on someone suffering from B12 deficiency can result in devastating neurological effects.
Like I said, it's definitely a shot in the dark but it's definitely something to think about.
Meanwhile, according to the article, symptoms began to appear far earlier. There is mention of migraines in 2009 and 2011 appears to be the start of some sort of sleep disorder (him sleeping for three days is used as an example) as well as the beginning of marked personality changes.
All this was already underway before the 2015 surgery - the surgery seemed to accelerate the deterioration but does not appear to be the trigger.

Here's an interesting quote:
"Additionally, infants and children with congenital heart defects often show disorders in folate metabolism (low folate, higher homocysteine, or low vitamin B12)."
Considering the surgery was to repair a leaky aortic valve which he's had since birth, it just seems like another data point.
Just my two cents.
