Is it a part of dementia to no longer experience hunger pangs?

Trying2B, If she tells you she is sick and tells the brother she is fine, she is manipulating you. It's called "divide and conquer", where the parent keeps the children arguing among themselves and therefore maintains control.
Your mother sounds like early stage vascular dementia, typical with CHF. I watched my MIL browbeat her daughter, play the guilt card on one son and tell the other she was fine, told the MD she was fine. Support your brother, he seems to have the best luck with her dementia.

Your mother could also be experiencing a lot or all of these symptoms as a result of the many medications she's on. If I was you, I'd take her list of meds to a pharmacist and ask about her confusion, etc. to see if the meds could be causing it. If her doctor was able to reduce some of her meds, her mental function might improve.

There are several things that contribute to loss of appetite in the elderly, but since you are unable to get at the cause you can only try to deal with the results. Loss of weight can lead to frailty, which leads to falls. Ideally she needs to be somewhere that her meals are placed in front of her and her meds are distributed as needed. Barring that, here are a few ideas:

The pharmacy can put her drugs into blister packs, then it should be obvious at a glance whether they are being taken properly or not. BTW, perhaps your brother has explained what her pills all are but she doesn't remember. She doesn't really need to know, she just needs to comply.

What about meals on wheels, then she will get at least one proper meal a day?

Perhaps the idea of eating a meal is not appealing. Try to supply a lot of finger foods and healthy snacks, precut slices of cheese, little clusters of grapes, small yogurt cups, you get the idea.

Trying2B, is your Mom forgetting to eat something she had done most of her life or is this new? I tend to forget to eat, too, maybe because I hate to cook and just don't want to bother :P

I don't think my husband was every hungry at any time in the ten years after his dementia diagnosis. He liked food and liked to eat and as long as food was placed in front of him all was well. He'd never remember to eat on his own, even if I left reminders.

At some point it is not safe for persons with dementia to live alone. Whether your mom has a formal diagnosis or not, perhaps that is the subject you should focus on. Is she safe to live alone? Are there some things that could be done to make it more safe?

Meals on wheels may be a good option for your Mom.

Maybe it is time to call the Dept of Aging where she lives if you can not get your brother to communicate with you about your mother. She needs to be evaluated for competency. Her doctor can do a quick 30 question test in the office to give you feedback as to how bad she really is but you would need to be with her at the office. Unless you are there in person they will not be bod to tell you anything over the phone. She needs an advocate for her such as a social worker. Not eating right, not taking medicines correctly, not bathing, sleeping too much are sell signs that she needs help. Please act now before something happens.

Trying2b, your mom and brother have put you in an impossible situation. And what has it gotten you? Very sick from your description. You have two choices in my opinion. Continue on the way you are and get sicker and sicker, or detach with love until something changes.

Let brother handle more of mom's care. Offer mom options (like switching POA) and if she doesn't make the change, then don't be such a listening post for mom. Cut down your time with her. Let the chips fall where they may.

In so many cases on these boards, a real crisis is required for things to change. You've had many mini-crises, but you're always there to pick up the pieces, so things go right back to where they were before, with you beating your head against the wall.

If mom won't give you POA and brother is intractable and inflexible, then you can either continue as things are (and pray that you're not one of the 30% of caregivers who die before their loved ones) or shake things up on your end. You can only do what you can do. Do you owe your mom your life? Because that's the direction it's heading, based on your comments.

There's great advice here, so I'll only address the hunger issue. When my loved one started with dementia, she lost a lot of weight. We didn't understand why she ate so little. She basically lived off of small amounts cakes, chips, cookies and ice cream. I would make or take her chicken, potatoes, green beans, pasta salad, steak, and pizza but she would not eat it. She just said she would eat later, but later never came.

Even when she first went into regular assisted living she would pick at her food. (They had to go to dining room for 2 meals per day.) HOWEVER, once she went on Cymbalta for depression and anxiety, and got settled into Memory Care unit, she started eating fine. She now has a good appetite, but her dementia has still progressed and she has still lost a little weight.

I believe that the dementia alone can cause the loss of appetite, but so can depression.

I would think that medication regulation might help your mom's mood and help her gain her appetite, but if she refuses to take it, you can't force her. It may be that she is just not thinking clearly and is not able to comprehend how the right medication could help her. If down the road, she is in a facility and others are making some medical decisions on her behalf, perhaps they can get her meds regulated and get her on something that works well.

Again thanks to everyone. I will try to answer everything. Yes, she always ate properly. She "forgets" to eat ... has no "hunger pangs" she says. No signal from body to eat. Meals on Wheels we had in and the food is not possible to eat (I tried it .. awful stuff). I cook for her, bring over frozen. She doesn't defrost it. Brother buys Chinese. Eats that but not good for her has she has congestive heart failure, fairly advanced and salt is OUT. I do not have POA, my brother will not have her assessed and disagrees with my suspicions. When she was in the hospital this time (many times, many falls, many close calls .. it's been really hard.) She has not been decalared to have dementia so no one will listen. Protective Services says she has the right to do what she wants in her own home. Hospital, this time, said "she cannot be home alone". Needs a nursing home. Then sent her home anyway. They say she needs people in. She won't have people in. Says no to it .. that City employees she had in the past treated her poorly. Very agitated. Gets angry if I suggest. Brother will not speak to me or other brother or anyone for that matter. Is controlling all of it, thinks he does the lions share re he IS the one who always takes her to doctors. He just doesn't see it and even if he did, it is still her right to be in her home. I want to act on this, but my hands are tied. Medication: they are put into 7 day packs and he makes up a month at a time. What may be happening is she drops them on the floor, or forgets or I just don't know anymore. Sorry. Really stressed here. Social worker came into home and she dismissed her. Same for nurse. Told the nurse she will be coming to live with me. Not true. I cannot take care of her in my home as I am quite ill myself. Doctors will not talk to me and my brother will not listen. No one sees it but me. Maybe I am imagining things? I wish I were. Brother calls her a liar; I believe she does not remember ... I have noticed all of this many times. He will not listen. What are blister packs? She does bathe. Doesn't eat right, does sleep a lot due to Congestive heart failure and extreme exhaustion all the time. I know they told her to take Ativan 2x daily; then my brother told her NOT to and that she might fall. Doctors have readjusted the meds so many times. She does not have a dementia diagnosis. I hope I answered everyone. I will try to get smaller things as one poster suggested.

One thing I might add: she tells me the "truth" and with my brother she says almost nothing. He speaks to her for a few minutes and gets off the phone. She even asks her not to "speak" when he takes her to hospital or for doctor visits. He asks us all to "change the subject" if she compains about all that has happened and is happening to her. To make her depression go away, I guess. I agree and disagree. I think she also needs someone who will listen and try to calm her ... she is very very afriad and agitated all the time. I just don't know what to do anymore. It broke my heart when she asked me to come and take care of her. I want to but am homebound myself. So guilty here.
