I am a pediatric emergency room physician. We occasionally diagnose Kawasaki Disease (now properly called Kawasaki Syndrome ) in young children. There are so many things wrong with the story of Jett's death that I am not sure where to start, but here's a try:

1) NO association between Kawasaki and "toxic carpet cleaning chemicals" (or any other environmental cause) has ever been established. Given that these chemicals are ubiquitous in our society, if there were an association I would expect Kawasaki to be much more common.

2) As far as I know, Kawasaki disease does not lead to brain injury or seizures. I suppose one could conjecture that if Jett had untreated heart problems from Kawasaki (which CAN happen) this could have led to a heart attack that led to seizures and death, but it sounds like Jett had seizures for a long time, which makes this a bit of a reach.

3) It would be incredibly rare to bump your head and die from a seizure.
