| But his cardiac surgery was in 2015. 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. EDIT: Came across this paper while browsing PubMed: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6837928/ 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. |
