Hello Boss2011
I am so sorry that you are facing aggression from your husband. My wife is in mid to late stages and can explode with aggressive behaviour towards me for no apparent reason. Her strength during these episodes is unbelievable so I really hope you are able to stay clear of your husband when he becomes aggressive towards you.
I become frightened of what she may do, not only to me, but to herself. The only action I have found in the interest of both of us is to leave the room, having first made sure there are no items with which she can harm herself. This allows her to regain her normal self and me to take a few moments to relax out of harms way, but it can sometimes take 30min or even an hour or more before I feel I am getting a 'normal' reaction from her when I go to check she is OK. It is like walking on eggshells as you can never be sure when or what might trigger the resistance, awkwardness, and aggression or when she has fully regained her usual self.
I think I can now read the situation better than I did, although there are no guarantees, so if I suspect my wifes actions or reactions to me are leading to negativity or resistance, I continue to talk quietly and calmly, leave what I was doing, and then put some soft, gentle music on and leave her with that. Not sure it is that or me leaving her to herself which eventually settles her.
I do believe these periods of aggression come in cycles as I have experienced it in years past and then had none of it for very many months after, and then it crops up again. In fact, I have just had a very bad week or two and yet for the last 3days my wife has been her normal affectionate and quiet, calm self. She has recently started on highly nutricional drinks recommended by a dietician and after reading the information on them, wonder if they are causing her to become dehydrated. In general I believe it is important to keep dementia patients well hydrated; I think I have read or been told about that somewhere.
Not sure I have answered your question but really hope you find something soon which helps both of you.
