Great news, Sylvia! At the very least you've got some lovely memories to draw on, at best this adjustment of medication will make a longer term difference. Re your meetings, I think 'treading carefully' sums it up very well. We all know there are no easy or straightforward 'solutions' to helping someone with AZ or other dementia illnesses (once they have reached a certain stage of their illness) to understand that their perception of what is happening to them and their carers is different from the reality. Unfortunately, as the illness progresses, the person's cognitive and social understanding declines to the point where it becomes increasingly difficult to reason with them. They just do not appreciate the effect their behaviour is having on their carer. They would be totally shocked and horrified if they had their normal understanding.
I really think you have had a positive breakthrough with Dhiren attending that meeting. Why he attended, or what he saw as its purpose, matters less than the fact that he accepted that his needs and yours took you into different meetings. You shared some humour, which you can build on for the next meeting, perhaps joking in advance about what the lady will take for her 'picnic' next time! He may, of course, refuse to go next time, but as he has been once, he is more likely to go again. He now sees it as a non threatening experience - no-one is labelling him by going. As for your meeting - I can only say that yes the 'experts' have much to learn, but how are they going to learn unless they have direct contact of this sort with people like you who really know what the reality of living with someone with dementia means? Ironically, therefore, the meeting which is intended to support the carers may in fact be a way of educating the 'experts'!
Approach the next meeting in a relaxed, light hearted way and you've got a good chance Dhiren will go. If he won't, he might go the next time. It's often one step forward and one (or even two!) back, but it's worth persevering as it gives you some opportunities for Dhiren to gradually accept more support from others.
So far so good, would be my view on this!
