My mother has been in a dementia care home for 5 months. 4 months ago she was started on memantine & that seemed to help her to remember how to go to the loo & do other things & also it calmed her aggression.
But she was still depressed & sometimes anxious and about 2 months ago she was put on citalopram - sorry, I don't know the dosage - and it has made all the difference. She now seems serene & content & since it started to take effect, all my visits have been 'good days'.
I don't know what effect it would have on someone who was a carer rather than someone with dementia, but it's certainly been helpful for my Mum. She is 96.
Yes, my mum thought she would have to give up being a carer for the one to two weeks of trying out a new antidepressant for side effects.
