Mom is in mid stage dementia and swears she is being beaten? Help? My Brother takes care of her and my father who had a stroke 12 years ago. Dad is completely competent but mom is delusional and says everyone yells at her all the time. Now she says my brother pushes and hits her. He would never do this, dad says not happening as well. Any suggestions on how to change the delusion to the more accurate helpful person he really is? He is getting increasingly frustrated at the accusations.
