I agree that the changes can be confusing, but there are some cases where the names are so confusing they are worth changing.

Take Borderline Personality Disorder. Sounds like it's just a "borderline" problem, not very serious. Yet, quite the opposite, it is one of the hardest personality disorders to treat and live with.

Another pet peeve of mine is the newly named "non-Celiac gluten sensitivity." Seriously? Naming a disease by what it is not?? I myself have either Celiac or non-Celiac and I'm not sure I want to be tested in case I am a "non" and then nobody takes my illness seriously. Celiac is taken very seriously, but I have not found any understanding or sympathy from medical people or the public about its cousin, non-Celiac. The name sounds like it's unreal or something all in your head.

You've got to wonder who comes up with these names!
