No matter what I do, my mom will almost always find something wrong with it

Let me first say that I am sorry you are going through this. Yes, this is a symptom of an ugly disease, but that does not make experiencing it any easier. If your mother was a sweet and understanding lady, I am sure this change in personality feels awful! On the other hand, if your relationship with her has always been difficult this can definitely open up old wounds and anger. 

I have walked alongside many families as they care for a loved one with Alzheimer's disease. It is unfortunately common to see mothers become cruel and mean toward their daughters. In your case, it sounds like she is not directing her anger at just you. While this may feel less personal, I am sure it makes finding supportive care for her very difficult. I have several quick tips that might help you cope with this situation. 

1. Stay tuned in to your level of anger and frustration. If you can limit the amount of time you or anyone else is with your mother you can limit the caregiver burnout. It is completely NORMAL to feel what you are feeling!! However, these are the feelings that can lead to acting out and abuse when not acknowledged. It doesn't sound like this is the case for you, but healthy boundaries and exercising respite will help with your feelings of guilt as well. So, rotate care as much as possible.

2. If you find yourself arguing with your mom, STOP. Don't worry, we have all been there before. No need to feel guilty, but this only serves to agitate someone. None of us enjoys being wrong and getting into an argument. For those of us who are able to logically engage with others, sometimes this type of interaction is necessary. Alzheimer's disease has robbed your mother of her logic, therefore arguing with her will only make matters worse. Try redirecting her instead.

3. Take care of yourself and seek support. Support groups and counseling are a great way to tend to your needs during this long journey. Caregiving can be overwhelming, lonely and heartbreaking. You don't have to go through this alone. Check out Alz.org for support groups in your area. 

Yes, certainly your mom's difficulty in having meaningful conversations with people results from the Alzheimer's disease process which weakens her brain function.

Feeling a sense of guilt in relation to a parent, is pretty common for everyone.

This is because as little kids and babies, we had a strong reliance on a parent and believing every word they sad and wishing to follow each action they ask or demand, was for the benefit of our own survival.

One way of coping with your feeling of guilt is to examine it.

Ask what it is you're feeling guilty about?

Chances are that your sense of guilt is less due to what you're currently saying or doing to help your mom.

Very likely, your guilt feeling is awakening the sense of obligation that you and all of us feel toward a parent simply because parents seem to have unquestionable power when we are very young.

After all, you're thoughtful enough to write a question, so chances are great that you're already actively involved in caring for your mom.
