It can take years for dementia to fully kick in, and show all symptoms. Have you tried taking your mom to the doctor, to see if she/he might be able to help in some way? While she isn't old enough for AARP to kick in, doctors have been educated in recognizing signs of dementia and finding techniques that work for different people.

There are different causes for dementia, finding the proper cause would be very helpful. So, I'd definitely recommend taking her to her doctor. Some cases first cause emotional outbursts; then comes a loss of speech; I can't recall which one that is...I want to say Parkinson's. ?? Check out the link that I copied. Hopefully, that can/will help you!

Very best wishes to you and your mom!
