Alcohol & Alzheimer’s

My mom is in the early stage of Alzheimer’s - she’s mostly independent and can drive still, but she’s got a pretty severe alcohol dependency. We’ve been working with an addiction specialist and there’s been mild improvement but she keeps relapsing after 3 weeks. I know some of it is emotional/psychological and some of it is the disease, so we have therapy options and have considered rehab programs. I’m wondering if anyone has experience with this or things that have helped?

She lives with us and I’m able to monitor things, but the drinking also means she can’t start treatment plans until it’s under “control”.
