The worst issue my mom has now with dementia is loosing track of time, not knowing what day it is, confused about meal times etc. However, there are little things she does that I'm wondering if they are part of the dementia: 1) She tells me the "people in her AL dining room are are old and ugly." (she is 84) 2) She will talk about people being fat and yet she is 208. 3) She will hone in on something about the way someone looks such as their teeth or nose and comment about it. Not directly to them but inappropriate none the less. 4) When the aide comes to bring her meds in her AL place, they are in plastic packets, with the name of the meds listed. She saves these empty packets and got very mad when I tried to throw them away. 5) Walking down the hallway she might notice a scuff on the wall and then proceed to tell me "this place is such a mess. The baseboards need to be painted, etc." The place is nice and clean, in my opinion. 6) Extremely worried about how she looks, if her navy blue pants are blue or black and if they precisely match the color of her shirt. All of these things have been going on for awhile but I really didn't think it was dementia but could it be? Or is she just odd?
A thorough assessment is needed to obtain a relatively accurate diagnosis. The diagnosis is needed for present and future medical, legal, and financial decisions.
My mom fought me the whole way and and even threatened to jump out of the car when going to and from the assessment appointments...but things are calmer and we now just refer to the results as "the short term memory problem".
Is there a geriatric psychiatrist who can see your mom? In my experience, these folks can sometimes work wonders with meds, ameliorating mood, obsessions, agitation and depression without causing excessive drowsiness.
I know how my mother has acted for all of my life, so if she was calling people names, making a big deal out of nothing, then I would take it that the dementia was causing it. It sounds like she is quite observant. I might use that to her advantage as she sounds able and willing to discuss what is on her mind. That can be a good thing. I would just ask her lots of questions and let her describe anything on her mind. It should be amusing.
