A few of these seem a bit odd to consider diseases. Stuttering and Nervous Breakdowns are conditions, but perhaps not proper diseases? Their sources do suggest that they can be cured by Clerics. I have not included other mental illnesses such as the madness caused by Contact Outer Planes.
What about the plague that spread in Glantri during WotI? Was it a variant of the Bubonic Plague? Or something else?
