Hi, my dad has been in hospital for the last 3 months, and has been diagnosed with Alzheimers. His memory hasn,t really been affected up to now , it was mainly his behaviour that was troublesome, he became agitated and very irritable , the nurses told me and my sister that he was smearing his pooh as well, but on good days when we visited him, you could have a proper conversation with him, just like when he was well. They tried him on Aricept but it seemed to make him worse and swapped to Mematine. The doctor then put him on Risperdone , a very low dose of 0.25mg , and we definitely saw an improvement in the agitation and the pooh smearing stopped as well. For some reason the doctor said he was going to increase the dosage of the Risperdone to one tablet in the morning and one in the evening, now in the last week, we have seen a change for the worse. Yes my dad seems calmer, but he seems zombie like , the nurses have said he is sleeping in late till 12 or 1 pm, it is very had to make a conversation with him and it seems his memory is not as good as it was, also he seems to be like he is drugged and zombie like , I know this could be the decline of the illness, but is seems a bit too much of a coincidence that this has only happened since the dosage of Risperdone has been increased. I am going to his ward round on Wednesday and will being talking to his consultant, as I wondering if really they have increased his dosage because it makes life easier for the nurses. Has anyone had experience of anything similar with Risperdone ?
