How do I deal with my parent that always blames me for past mistakes and doesn't trust me?

I have a 51 year old mom. When I was a teen I didn't really like to clean my room and I would eat in there too and out of laziness I'd also like to hoard plates in there sometimes, but I've grown up and cleaned myself up, but now my mom as her memory gets worse she keeps blaming me for not finding any plates or just anything really cause when I was a kid I used to take her stuff to act mature in school and now whenever her stuff is missing she always blames me, but it's not all my fault she likes to clean and when she clean she place things differently and she forgets! Sometimes when she really can't find one thing she needs urgently she barges into my bedroom and forcefully looks through my room while yelling at me. Whenever she lost anything the first thing she thinks is me! It's been years since I haven't done that yet she still doesn't trust me at all! It may be her menopause but I just don't know what to do with her anger issue, and when I find something for her she still doesn't believe me and says I still stole it from her, I've even recorded how I find her stuff, I really don't know what to do with her issues. I'm tired of her hurtful words I've had some break downs too.
