I hope the developers are in the process of creating fuller, more precise information. Many, if not all, of the definitions are very vague and bordering on completely misleading. Along with a definitive terms, perhaps it would be beneficial to add a new little link in each to general symptoms. There are a lot of terms, so clearly that would be a lot of work to do. But hey, its psych. Nothing is black and white in psych. There are millions of acres of grey areas and to simplify any part of it, as this app has unfortunately done, is an injustice to those with mental illness everywhere. Knowledge is power but if that knowledge is wrong, ignorance is born.
