Hello,
@anitad26 . I'm sorry to hear about your mum's distress. Hallucinations and delusions were a major part of my husband's dementia. Nothing benign about them, he was absolutely terrified, all the time. He was first tried on quetiapine and xanax, but it had no affect. A couple more combinations/doses were tried, but then he was put on Risperidone and trazodone. That worked very well. Risperidone is a powerful drug, and not normally recommended for the elderly. It
can have very severe side effects, including sudden death. However, with my husband, his consultant and I decided that we had to weigh up quality of life over quantity. My husband was living in a nightmare, from which he got no relief at all. The medication also needs very careful monitoring. Initially, my husband was seen every week, and eventually every six to eight weeks.
Thankfully, he actually suffered no side effects at all from the medication. Not everyone does. And, also thankfully, the combination of meds worked really well. It was literally like someone had flipped a switch, and turned off his hallucinations and terrors.
I hope something can be found to help your mum. Dementia does enough damage to people, without hallucinations terrifying them too.
