I am astonished that my mother has gone from no signs of dementia all the way to stage 5, in only two years. That seems very rapid. I do understand that it's just a guideline, but each of these stages seem to last a year to several years. Anyone else "tracking" their loved ones this way, and if so, has it progressed this quickly also?
i do believe that at a point the dementia can regress rapidly. an extremely intelligent person may mask the mental effects somewhat. these are just my opinions and arent worth much more than the keyboard wear and tear..
