I want to share my feelings with you, but my husband is not diagnosed yet. He has symptoms of possible Parkinsons, or some other neurological impairment and he's going for tests after the holidays. For some time I have experienced him as moody and isolated and - to be honest - I would welcome knowing there was something wrong, other than us just growing apart and him being impatient with me. How do you know whether it is a form of dementia or just grumpy old man? (Both sound pretty awful, actually). Very occasionally he bursts out with rage - always against me - and occasionally he is very warm and loving. I think our marriage has been deteriorating because of his coldness and withdrawal for about five years, but I have thought he was unusually forgetful of anything I say, and unusually withdrawn for the past three. His clerical assistant thinks he has deteriorated in his thinking and work. I don't know what to think - both options are depressing, and of course one is very serious indeed. I wondered if anyone had been in my position or understands these feelings?
