I have a different perspective on this than some, I think. It comes from 2 places 1) I'm in these shoes and have met with doctors, etc, to get help for my loved ones (and memory loss is rampant in my family, unfortunately) and 2) what I've learned is that there really is no effective treatment for dementia/memory loss (the 2 meds out there only work very early on, and even then only to a small degree) so while it would be great if your relative would see a doctor, to be honest, there isn't much doctors can do. And facing memory loss is scary, so it's not surprising that she's in denial. So forcing her to face the issue isn't always useful since there is no treatment. In this case, how to handle it?
- write things down. We find having a written calendar on the wall at her house is actually better than an electronic one. This is because when we are around, we can take a look at the wall calendar, correct anything that's written down incorrectly, and also write things down that aren't on there.
- someone needs to know her medical history, including what meds she takes daily. She should have one of the boxes for meds that has compartments for morning, lunch, and evening with the day of the week so she can keep track of what pills she's taken, and when. Memory problems can be GREATLY aggravated if she messes up her medications for any other conditions she has. If possible, someone else should dole out the pills into the case to make sure it's accurate.
- help to keep her active. Physical activity is pretty much the only thing that correlates with keeping memory from deteriorating. If there are relatives nearby, it would be fantastic is someone would commit to going to her house and taking a walk every day. It can be that simple.
- for any important event (family events, doctors appointments, etc), plan on someone picking her up and bringing her, so she doesn't miss things. Don't say it as "I'm going to take you so you don't forget" Just say "I'm going to be in the area that day, why don't I pick you up so we can spend some time together."
-keep an eye on her driving, and have a plan in place to take her shopping, to events, etc, when the time comes that she's no longer capable. This is one of the hardest things to deal with. No one wants to take away a person's independence. With my family members, they don't forget how to drive. But it will likely get to the point where she will go somewhere, and then not remember where she's going, or how to get home. This is when it gets serious and you will need to involve a doctor at this point even if she's still in denial.
- let all the small stuff go. She doesn't remember that she's told you the same story 3 times, or asked you the same question 4 times already today. The kindest thing to do is to listen and answer as if you haven't heard before. Don't take it personally when she forgets a grandchild's birthday. Because she really doesn't remember. Important conversations, get in writing, and as much as you can, let the rest go.
- loving someone with memory loss is a reminder to live in the day and enjoy each moment as it happens. Will she remember later that she was laughing and having fun with you? The reality is - no. But YOU know that in that moment, you and she were enjoying each other. Cherish that.
