My mom 87 has a very general weakness and feels that she is dying - almost everyday now...for months. She has home health care aides for years. Her blood work is perfect although she does get UTIs. With all the medical intervention, we CANNOT figure out what is causing this awful weakness! They think the spinal stenosis but this is frustrating. Trying to get her palliative care but none exist in her county.
Health issues:
-severe spinal stenosis (impaired mobility)
-depression
-metabolic encephalopathy
I would look into hospice for her. It’s not just for people whose deaths are imminent. They handle physical and mental care. My mother just enrolled and so far we are very pleased with the team we have.
In her early stages of dementia, instead of acknowledging that she was forgetting things, my mother blamed everything for being broken, us forgetting to tell her anything, etc. Although she was mobile, quite strong and good physical health, she vehemently denied cognitive decline, instead focusing on her virtually nonexistent physical decline. We kept her active, walking every day, weather permitting. But she would get in this strange mindset that she was frail and dying. It might last for hours or days, then she’d be fine. But she did return to the issue repeatedly for almost a year. One day we watched (and photographed) as she used a mop as a crutch and dramatically struggled 55’ over to us, explaining that wanted us to see how she was dying and too weak to make it a few feet to reach her walking stick that stood by her front door. (that she had walked past, to get outside to us) Just then, a neighbour pulled up our driveway. She dropped the mop and scampered over to the car for a visit.
We supposed that her mind looped on a fear and, until she was distracted, she acted out that fear.
This is strictly anecdotal - no medical explanation.
Speak with your mom about whether she is depressed, or overly tired. Check her blood pressure daily and be certain she is hydrated. Speak with her doc (whomever is POA) and then perhaps you may just need to accept that for her things are winding down a bit now.
I did a quick search of clinical articles(1) on depression in the elderly. Besides acknowledging that it is a huge concern since it speeds physical decline, common ways to address/prevent it were:
~ medication can alter chemical signals, reducing symptoms
~ spirituality/religious belief that provide hope can empower a person to better cope with their situation, relieving them of the hopelessness that's so disabling^.
~ cognitive therapy can help a person adjust their thinking, avoid looking back at 'I used to' and focus on 'what I can do today'... [One benefit of the pandemic is that Medicare is still covering virtual therapy...]
~ physical/mental exercise can stimulate mood, improve circulation... A couple of articles said robotic pet therapy was shown to reduce depression, pain, stress hormone levels, boredom, and loneliness while increasing happiness and quality of life! (On a personal note, I was amazed to learn how just a life-like stuffed puppy boosted a terminal friend's mood! It gave her something to fuss over, talk to, talk about - it gave her joy.)
We KNOW aging is HARD. But quality of life can always be tweaked.
Best wishes for your family.
