My Mom has dementia, and when she gets emotionally upset, it usually shuts down a lot of her other brain functions....she become really confused! And yes, I find that she has good days, bad days, and things fluctuate.
What types of symptoms are you talking about specifically?
Yes, they can. One day my mom is fine for a few hours and the next thing I know, she goes back to square one. I'm trying to learn how to deal with it. The ups and downs are nerve wracking! Trying to cope with it is a real challenge and I wish you the best of luck. This forum is a great way to start. You can vent all you want and get some really good answers and suggestions.
