Memory loss is often less of an issue in LBD. There are more physical symptoms with LBD (similar to Parkinson's -- which also involved the protein clumps). All types of dementia involve variability but in LBD that is a core symptoms. There are good days and bad days and good hours and bad hours. It is so extreme that persons only familiar with AZ may thing the LBD person is faking symptoms. "He could do that perfectly well this morning. He is just wanting attention saying he can't do it now." AZ often includes eventually losing the ability to recognize family; LBD seldom includes that.
All kinds of dementia can include sleep disturbances; LBD is strongly associated with a specific sleep disorder called RBD, in which the sleeper acts out his dreams.
AZ progresses in a generally recognizable pattern. Stages have been identified and can be helpful in knowing what to expect. LBD does not progress in "stages" -- it does get worse over time, of course, but that tends to mean the "bad" episodes last longer and are closer together, not that the person goes on to new symptoms.
Those are just a few of the typical differences. While the differences in the brain are very distinct, it can be harder to identify the diseases from the symptoms. LBD is often misdiagnosed in the beginning.
The AZ and LBD websites provide a lot more detail.
Confusing isn't it? --that's the world of dementia: my wife and I recently met our son to pick up our grandaughter for a weekend visit; while I was sitting in the car my wife and son talked outside; he bent down to talk to me and I visually recognized the 33 year old man he has become, but my mind told me he was supposed to be a teenager. That's memory and dementia!
I find, however, my capacity for loving others is unchanged; indeed it is larger than I ever imagined. Love is caring, and is not necessarily romantic. As I mentioned, my love for my wife and family is unchanged. I have come to realize my love and respect for God is greater than I ever previously thought possible, as is my dependence on and faith in Him, His Son and His Spirit. And I have a deep and abiding love for many other people; people who I have never seen, nor have I ever met--people such as yourselves with whom I have only had contact through the internet or facebook, yet with whom I feel a closeness and kinship, the kind only experienced through love for another person (e.g., through facebook I am acquainted with a couple in Canada who I would love to meet; I truly care for them, and love them, as much as any other member of my family. I only regret we will never actually come face to face in this life anyway)
Going places? I prefer to stay in my den, in my recliner, with my little carepartner - a 14 year old dachsund. My wife is a 36 year RN (great advantage when I have to go to see a doctor). She is a marketer for a psychiatric hospital and travels throughout west Texas: from Amarillo, to Lubbock, to Presidio and Del Rio, to Pecos and Van Horn, to Killeen and Ft. Hood, to Austin. Home base is in the middle, San Angelo, and we live just outside Midland. She covers an area larger than most states (check it out on a map) and is often gone for 2-3 days at a time! Yet I am fortunate enough, at this point, remain home, alone. Dr appointments are worked around her schedule. We have a couple of neighbors I can call on if I need something badly (I've only had to do that once). I can still drive the couple of miles to the Dollar General or the convenience store for milk or dog food, but I prefer to stay at home.
We used to be devout church goers (Sunday AM, PM and midweek). I led singing, prayers, and served communion while my wife taught a class of kindergartners and first grade. Church attendance is still extremely important to both of us, but I rarely go now. I've found, though I enjoy the services as a whole and usually feel edified by being there, I tend to get confused and/or lost in the bible classes and sermons (I wish the teachers/preachers, when they cross reference other parts or verses, would finish with one before going to another), and sometimes the other attendees make me feel overcrowded which leads paranoa and disorientation, all of which results in general confusion, discomfort and "isn't it over yet?" Not worth the risk of disrespecting the Lord or any of his servants; He knows I haven't forgotten Him.
I usually force myself to go with my wife to pick up our granddaughters for a visit or to go to the grocery store; otherwise, I usually stay at home. Why? It's safe! I've had too many experiences of not knowing where we/I are; I've been lost, disoriented and paniced in stores, while standing next to my wife, too many times. I'm concerned about becoming lost while talking my care partner for a daily walk (I wear a medicalert dog tag and use a wonderful cell phone app--Watch Over Me--I highly recommend it) and though I am able to, I don't drive anywhere (including backing the car out of the driveway) unless I absolutely have to (might wind up somewhere I don't want to be and not know how to get back). In short, I have a tendency toward paranoia and panic (also parts of dementia) and prefer not to take the risks.
In addition, I've reached a stage where I sleep--12 to 14 hours at night and generally a 1-2 hour nap in the afternoon (sometimes after being up for only a couple of hours); and I'm becoming more and more incontinent of bowel and bladder (I carry extra depends in both cars). Those latter two things (sleeping and incontinence) are much more embarrassing than not recognizing someone.
I hope this all adds some clarity to your concerns ND-18. Dementia (all kinds), regardless of it's source (mine was triggered by surgical anesthesia in 2010) is a very complex disease, not restricted solely to memory, which is where most people, including us, tend to focus and expect problems. It is one l-o-n-g roller coaster ride that one must learn to enjoy; for there IS LIFE after dementia, and the patient and the caregiver should NEVER GIVE UP.
Hope this helps. God bless you all.
If that is the case with your mother, she will not begin to feel it now that she has dementia. So it may be good to stop looking to her for what you hoped might be there. There is love all around you, though, so I hope you find it in other people. This doesn't mean that you have to stop loving and caring for your mother, only not to think her not returning the feeling has anything to do with you. You sound like a daughter who is seriously capable of love, and you sound like you're doing your best to take care of her. Go easy on yourself since it's not you. It's her.
Dad had always been a gentle person but the last few yrs of his life, he fought my mother with a vengeance. He was sweet as pie to everyone else but her. We think he was getting back at her but who knows and it doesn't matter now. I miss him terribly.
That period aside, my husband never lost his ability to show love. It helped that he never lost his ability to recognize people. I think it also helped that he accepted and understood his diagnosis and therefore had an explanation for why the world didn't make sense and why we couldn't fix it for him.
Even when he was talking gibberish, he would still say "thank you" for small services.
Different dementia types have different symptoms. Some include not recognizing familiar people, some do not. Some have accompanying physical disabilities. Some have less of that. And each individual is different, too. So I don't think we can generalize about if/when people stop being able to feel or show love.
My husband was diagnosed with Dementia with Lewy Bodies. He died in November and I'm awaiting the results of the postmortem examination of his brain.
There is research showing differential physiological responses to familiar versus unfamiliar people that is not otherwise apparent. One article I read specifically about Alzheminers describes it as losing memories from present to past - so that first a grandchild born a few years ago would not exist in that person's conscious memory, then maybe a second spouse of a decade long marriage, then maybe the person does not remember the deaths of their own parents and wants to call them. This may be hard to hear, that there is still a person inside that dementia masks in such a way, but maybe a comfort in some way too.
Once when my Dad was having a bad day, my son just kind of assumed that we wanted to get out of thee ASAP and "that's not Dad anymore" but I know I found the opposite was true the more time I spent just hanging out and doing whatever he was still able to do. Everyone who got to know him realized who he really was, his likes and dislikes, despite his various inabilities.
I agree with vstefans, depression can be a huge factor in not caring. I think people with dementia can get depressed.
My mom also avoids many things she used to enjoy with or without us becuase they are too cognitively difficult or embarrassing for her. She stopped going anywhere except to the doctors also when she could still travel - got in a van to see my dad maybe once every week or two then stopped that too. Culturally that's what people of that generation do, its the old "sick role" whichis also embodied in Medicare policy; the only obilgation the sick person has is to get better, they are otherwise supposed to just stay home and let other things goo by the wayside. Frankly, it makes people embarce invalidism when applied to chronic rather than short-term situations but that's another story.
I have had to comfort myself with the realization that Mom is doing what she thinks is right and it is not for me to take that away from her. She does not think she should do things that she can no longer do well and prefers strongly not to face or discuss any negative emotions, or any possibility of criticism as she is also very perfectionist.
My Mother, who went to church all her llife until two years ago this past September, allegedly loved God too but after she came home from the hospital after having fallen and broken her hip, which she came through with flying colors, never went back to church again.
She used her legs as an excuse (that's one of her favorites) but she manages to get to the doctors and back. She also hasn't said the "blessing" at her meals since then either, that I know of. She used to say it faithfully at every meal. When I asked her about why she doesn't say it any more and is she mad at God, as is customary with her, she wouldn't give me any answer. How can an illness cause her not want to go to church any more (she watches a couple services on TV) or say the blessing any more?
I really don't understand what one has to do with the other.
She has never been a person to show much expression of love but she always talked about it as if she felt it so I thought she did. I always thought I got my ideas about love from her. But now I see no signs of caring for anything or anyone, not even herself, in any way shape or form. A few year ago, someone (one of those pillars of the church) hurt me so bad that I was practically heartbroken. When I tried to talk to her about it (I expected some comfort), she just kept looking straight ahead at the TV, saying nothing. When I tried to get her to make a response, she said she didn't know what I wanted her to say. I bet most people could think of something to say if someone hurt their child or any loved one as much as that person had hurt me.
I honestly believe that she would be just as satisfied with a mechanical robot here instead of me if it was able to do everything that needs to be done. And I don't think she would care if I sent her to the nursing home. I am doing everything in my power to keep her here at home, which I've explained to her, but she doesn't seem to care one way or the other.
I was so frustrated and upset with her this morning that I was beside myself. She is deteriorating fast, both physically and mentally, and she doesn't seen to care, because all she does in sit in her chair with her hands in her lap and stare at the TV. No matter how much I beg or hollar, she won't even try to do something to help herself, something as simple as gettig up and walking with her walker back and forth through the house except when she has to go to the toilet. I told her this morning that she's worse off than
Stephen Hawking (a severely disabled scientist) because even though he can't walk or talk, except through a computer, he still CARES. She doesn't. No matter what I say, she won't give any response. I told her that treating me like that shows exactly how much I mean to her - NOTHING. Still no response.
When her eyes got so bad that it wasn't easy to see, instead of trying to use a magnifying glass (said it had a glare on it), she quit reading.
If it isn't the dementia, what could possibly make a person so totally empty of feeling?? If she didn't have alzheimers, I'd take her to a psychiatrist.
