While my grandmother doesn't have dementia, caring for her is NOT easy. She has short term memory problems but that's also her cop out when she lies. Granny is well on her way to being demented. I never knew how evil old people can be until I started caring for granny. I hope my parents are easier to deal with. What aggravates me about my mom is that she is spineless when it comes to her mom. She will not tell her mom no. Both mom & granny work my nerves.
