How do I tell my mother that her older brother was just diagnosed with liver cancer and hospice was called in?

Will your mother remember this if you tell her? Will it really upset her? Or will she forget as soon as you tell her?

IMHO it depends on whether mom can handle and process the information. I would ask her doctor. The worst thing would be to make her condition deteriorate.

My dad did not have dementia. But some of his relatives do have dementia and we did not tell those members when he passed.

Sorry to hear this about your Uncle (your mom's older brother)
I would use as much caution as you think your mom handle-Dementia is very strange in regards to what one person may be able to process another may not.
With this being said-I would then decide just how much information you can give your mom ...I personally do not think there is a clear cup reply to this question-just an opinion.
If you are still not sure which direction to take-contact your local chapter of the Alzheimer's Association for further input, or your mom's physician or neurologist.
Good luck!

Just sit down and tell her. If she remembers what you say, then so be it, if she does not, tell her again in a few days.

You SHOULD tell your Mom and she should have the option to go visit her brother and tell him she loves him and say her final goodbyes. If you keep this from her and he passes away, she could become bitter towards you and also, by telling her, you will never have the regret of NOT telling her her brother was ill and she didn't have a chance to say goodbye. I'm sorry for your bad news. May God keep you and your family in perfect peace during these trying times.

You did not state the mental or physical conditions your mother may have.
That would make a big difference in what you tell her. If she is fully aware and is emotionally close to her brother, she would probably want AND be able to process a lot more details than if she has limited mental acuity or is herself in failing health. It seems a shame to unload such sorrowful and hopeless news onto her if she is fragile or mentally diminished.
You could simply tell her that her brother is ill (not doing too well) and is under doctor's care. What could she herself do if she were constantly kept apprised of detailed developments in his health and medical care other than to sit and worry helplessly?

If she can travel, and wants to visit him, understanding that he is ill, that opportunity might keep her from feeling that she was unable to go comfort him or had 'missed saying goodbye' if he should pass away before she
does.

When my adult child passed away unexpectedly, I did not tell my aged mother.. I knew it would devastate her and engulf her in unbearable grief.
for the remainder of her life. She was in no physical or mental shape to deal with such devastating news. She passed away 5 months later, never having known her precious granddaughter had died.

Crowemagnum, I'm very sorry to hear about your uncle's terminal illness. What a difficult time this must be for you. Earlier this year, I mulled it over for an entire day before deciding whether to let my mother know that her last surviving, and youngest sibling, had died. I didn't rush to tell her. I prayed for guidance. That night, as Mom was starting to wind down for the night, seemingly out of the blue, she mentioned her sibling and speculated as to why she had not heard from that sibling in the past couple of months. When Mom started erroneously assuming that her sibling may have become upset at her for reasons unknown to Mom or me, I knew that the universe had given me a window of opportunity to let her know. I sat down next to Mom, held her hand and told her in my softest voice. Her eyes looked startled though not distressed when she asked me "When....?" I truthfully told her that her sibling had died earlier that day.

I don't believe in coincidences, nor do I believe Mom's asking about her sibling on the same day was in any way a coincidence. I share that all to say, give yourself a little contemplative time. If you're not a believer in prayer, it doesn't really matter, just ask Spirit, or the universe to lead you in revealing when, and/or whether to let your Mom know what she may need to know. It all depends. I know you'll do the right thing.

Sending positive thoughts your way, Crowe, including for your Mom and her brother. Life sure throws its share of curve-balls, doesn't it? Best.

Visiting her husband is out of the question for she is so immobile that she can only be transported by stretcher. He had a very good opportunity months ago to come and see her, but he said that would be too depressing. I kept telling them to come on and finally he sent his wife who had a good visit with her. My mom has a rather negative relationship with her brother compared to her sister and never has liked her SIL. Now, with this development, they cannot go to see each other. They can talk by phone and I agree that she should know about this for she's known for sometime that his health has not been good, but not like this liver cancer.

Perfect peace would be nice, but I think will only be known in heaven given my Bipolar II as well as my wife's and our youngest son's ADHD. Thanks for your supportive prayers. We can use all of those we can get.

I have taken my mother in law to viewings and funerals but the dementia has really affected her emotions. It is as if she hears things but she doesn't have emotions anymore. She doesn't remember the family members who have passed. She asks everything as a question...How is Aunt Helen? I will tell her that she passed 3 years ago and she then says "Oh yeh, I remember that now". If she gets upset because people don't come in to visit her I tell her that she is sick or he is taking care of his wife...Sometimes, I will say things like this even though not completely true because so many people no longer come to see her. She will ask if relatives have called about her and I tell her that they have even though we haven't heard anything. If it were my uncle I would just tell her that Uncle "Bill" is sick right now but I wouldn't get into the details. My mother in law wouldn't remember anyway. And she may ask again and again and I would repeat the same story again and again. I just never say too much that would really upset her because when she gets upset about things, she gets worse..I will keep you in my prayers...This illness is so hard to handle.

CROW,seriously with something as important as thisI would ask her doc. That could turn very serious,and depending on her usual way of handling things, it may not be same with info like this..............I wish I had more to say to u, as I like u,and as soon as I say who the question was from I answered right away.............I would definetly get medical advice on this one! let us know what happens, please, I care,really do!!
