My grandmother was recently diagnosed with dementia. Its getting worse pretty fast. She has a lot of paranoid delusions. She thinks that people are trying get into the house, that my sister is sick and dying, that people are trying to kill her. She threatens to go outside and chase the people off, she banged on the windows the other night trying to get them to go away and almost broke the glass. Me and my sister and my uncle are her primary caregivers. I would appreciate any advice on how to deal with these delusions. Trying to explain to her that they aren't real just gets her frustrated and upset. But i think its only a matter of time before she hurts herself. if her delusions were more harmless i would just go along with it, but I'm afraid if i do she'll run outside banging on the neighbors doors trying to get the "intruders" to go away and get hurt. This is all very sudden and I'm just not sure what to do. She's been to the doctor but so far they haven't given her any medication to help her sleep or anything which i think might help but i don't know. I'm very confused and overwhelmed. just not sure what to do.
