My MIL (80) and has Alzheimer's. She was diagnosed with Alzheimers 2 years ago and I suspect she is in the mild/moderate stage. I have read that recovering from broken hips is hard, but was wondering if anyone had experience with a broken ankle. It is displaced and will more than likely have to be pinned.
I might discuss the various options for anaesthesia and see if they can come up with the least severe. The stress and pain are other issues. Discuss appropriate pain meds. My cousin who is more advanced with her dementia did not do well with Percoset.
Post surgery care is also very important, as she may forget to not put weight on the healing foot. She would need to be watched a lot to make sure that doesn't happen. My cousin would also remove her bandages and forget why they were there.
How long will it take for her foot to heal?
I will say that my cousin who has Vascular dementia mixed with Alzheimers, she showed a marked decline after breaking her wrist. Then she was stable, then another marked decline after fracturing her spiine 4 months later. And another one the next month when she broke her hand. She's now in a wheelchair.
Of course I have no idea how your mom will do. Some people seem to stay more stable if they have Alzheimers and not other forms of dementia.
I wish you the best with your mother. I know this is so difficult.
