My wife has Alzheimers - she sleeps a lot and worries that it is the medications that cause this. Yesterday I took her to the french doctor where we live here in La Rochelle - I response to her question he indicated that it was not the medications - she is on Deroxat 30mg Tiapridal 100mg and Aricept 10mg. We normally go to bed around 23-2400 and she seems to wake naturally at 12.30 ish most days. The french Doctor indicated this was about right... Just wondered what the experience or views of others is??
