Many sources claim that Henry VI of England came down with the same mental illness that his grandfather Charles V of France suffered from. This means that technically Charles VI of France and Henry VII of England could also have inherited it, since they were of Valois descent.
I'm not going to get into the heritabilty of other mental illness but it's particular high for Schizoprenia (which Henry VI and his french grandfather are commonly thought to have had)
While it's hard to make a diagnosis from only chronicles (critically regarding the "glass desillusion" that while relativly present at this point, isn't nowadays): it's certain that he suffered from a form of psychosis, without certainty about schizophrenia (this retro-diagnosis being not commonly accepted, many preferring to argue in favour of a more broad bipolar disorder, less by schizophrenia being disproven than not really proven)
I think it's a bit of rationalisation there : it seems that he really tought his body was made of glass, at the point of "reinforcing" it by bands of iron (up to hurting himself with trying to put iron within his arm)
Furthermore, the whole "gemophobia" is contradicting with the documents : the king is described as living in a total lack of hygiena, litteraly covered by fleas, if nobody managed (or wanted) to take care of him (and even that asked for treasures of diplomacy and cunning).
But things going well for France isn't the same thing than going well for one person.If I remember the history a-right, didn't Charles the VI grow up in the period of the Hundo that was relatively good for France?
But things going well for France isn't the same thing than going well for one person.
Remember that he became king quite young, and a good part of his early reign troubled by the premices of the Civil War. Without talking of fiscal revolts (at this point, it was quite clear that French edge on the conflict, even if appeasing, depended on the fiscal capacity, critically when Charles V's ressources were dried out) and of course the general mental climate of the late MA.
He eventually had really few time to take care of that, being under quite a stress : from having quite a careless life up to 20 years old, his advisors being under pressure of nobility and one even barely avoiding to be murdered.
While you probably had a genetic background, you had as well a contextual ground for its devellopement on something huge.
