I've always heard and I tend to believe that incontinence is not a specific disease, but rather a symptom of a disease. So when I hear "Long term incontinence is not curable" it's like saying whatever is causing or leading to the incontinence is not curable and considering there are many causes for incontinence (like there may be many causes for a fever or nausea) this statement can be, at best, partly true. And you can't tell someone they are going to have to wear adult diapers for the rest of their life is you haven't fully exhausted the causes for the incontinence. And who's to say what future medical discoveries might tell us about "curing" incontinence too?
