Hallo pevensey, from what you say it sounds very much as if this change in behaviour is down to the reduction in medication. (It's memantine, I think.) Did he have very bad side effects with it? Is there any possibility he can go back on the full dose or try something else similar?
The doctor should talk to you privately about his case - in my case the doctors did about my mother. Perhaps he could see you first and then your husband. However, if he is now presenting as calmer again, he may decide to leave the medication as it is. It is hard to say what has caused it - it may just be a "blip" or it may be a pattern. I think you may have to give it some more time to see if he goes back to how he was again when he was better.
Loss of interest and apathy can be a symptom of the illness. It sounds like you did the right thing by taking him out for a walk and thus providing a distraction. Maybe you need to try things that divert him if he gets in this type of mood - I am sure you are trying very hard already. I sympathise with you about putting up with anger and aggression - it must be so difficult.
