My mother was diagnosed about 5 years ago. Our main problem is with her having dreams or hallucinations that she totally believes are true. She is in sheltered housing and has carers visiting 3 times a day. She completely believes she has another flat that she lives in. Tonight it escalated as she thinks there is an intruder. She completely barricaded the door and would not let the carer in to give her the meds she needs. Ended up with my sister breaking through the barricade of chairs,vases tables towels etc. she was able to calm her down. Does anyone else have this and any ideas how to deal with it?
