My mum is in a nursing home with dementia and has just been prescribed risperidone twice daily at 1.5 ml a day, she has been on this for a week and l have seen a great turn around, the doctor at the nursing home prescribed this, my mum is 70, and l am not sure if this is right, as l have read that it is not good with people with dementia, so l am not sure if this is wrong or right, l have also been told that my mum can change back at anytime, thank you
