Mother has dementia and needs to get a hysterectomy. What should we expect?

It is something to discuss with your family members if she is 85+ years old and or is in the late stages of dementia to choose not to treat this.

But you don’t give us any information to discuss.

Her dementia will get worse after anesthesia and it’s very possible she will not be able to recover from the surgery.

Really age would help and why a hysterectomy is needed.

You should discuss all this with the doctor, and let the doctor know the issues he/she will be dealing with. They will best know how to medicate for comfort during this needed surgery.

Best of luck.

How bad is the dementia?
Does she already have behavioral issues , paranoia etc ?
Hospital delerium may happen . There could be a permanent step down in cognition.

This question should go to her surgeon. Most offices hand out pre and post op instructions

You don't give us much to go on, like why your mom is needing a hysterectomy, how old your mom is, and how long she's had dementia, so it's tough to answer your question.
But I will just say that any time a person with dementia has to have any kind of surgery, you can pretty much plan on them have their dementia symptoms get much worse from the anesthesia, which can last a short time or be permanent.
And if your mom has dementia, which already is a death sentence, I'm not sure allowing her to have any kind of surgery is in her best interest anyway. That's my thought anyway.
Perhaps if you share more info, it may be helpful.

I’m curious how old she is? Thanks
