Mom's always been a happy person, lots of friends, the oldest of 10 kids, gets along with everyone. I've only heard her raise her voice 3x in my life. She obviously isn't the same happy person but she is still happy, friendly, talkative and can be engaging at times; its getting to be less so lately as her Dementia has progressed, she is in STAGE 6 Should I expect her to become combative and mean or disruptive? or is that as much a symptom of the illness, as it is a personality issue? I know this is probably not black and white but If there's going to be a personality change would it have likely already happened or is that more than likely a change that's soon to come between STAGE 6 & 7? Or is there just no telling?
