My 86 yr old mother has moderate to severe dementia. She lives in an independent living home with a great deal of help (daily) from my sister. Of course, she thinks she is independent and does not have dementia. She has been having hallucinations and delusions for 3 years, but they come and go, but lately, it has gotten worse. She sees people and animals in her apt during the day (and night), and thinks they are taking her things, and is somewhat frightened by these people she sees, and isn't sleeping well. We will have her checked for UTI, but wondering if it is time to ask the doctor for something to control her hallucinations? She has not become aggressive, and no big personality changes. We hate to start these until it is really necessary but worrying about what she might do. She wants to call the police.
