they had leading doctors view his behavior. this is how doctors diagnose people from symptomatic behavior. it doesn't mean it's positive but it was a concern. i'm wondering if he did have it or possibly a non cancerous tumor pressing down on his ability to think straight. and was treated for it. or even treated for cancer.  it's also not very advantages to keep it a secret. you just have a backup leader he choses and go public.
