There's not much of a useful distinction between these categories and words, though. "Disease" is a very general category that, depending on who you ask, contains all disorders. Many psychiatric developmental disorders do have clear established physical causes, so in that sense they're not much different than being born with a malformed heart, other than that the defect is in a different location.

The only real consensus is that "disease" does not describe traumatic injuries, e.g. if you break your ankle in a bike accident that isn't a disease. Note that many people conflate "disease" with "infectious disease", but the actual general category "disease" is quite broad and encompasses much more.

Anyway, it's arguing over semantics, like the perennial argument over whether Java parameters are passed by reference, or if their references are passed by value, or if they're passed by value, etc. See here: https://news.ycombinator.com/item?id=16896150
