I am concerned about my OH,who i have thought for a while is "not wired right". I have problems trying to follow his conversations,(which seem to go round in circles)way of thinking ect. I dont want to go into everything,but just a few basic points :: recently,he has started to change he will not take the dog for a walk..(he used to) not interested in his old hobbies..(walking,bird watching) his way of bird watching,now,is to hang a few nuts up,in the garden,and watch from window. has become obsessed with dvd's,,and always comes home with some from charity shops,which he makes excuses to get to 3/4 times a week. watches the said dvd's,at every opportunity. things we used to do,as a couple,he has no interest in now..eg,nice walk to a county pub,couple of drinks,walk home....not interested. not really interested in anyone else. gone very selfish,and self centered....have to nag,to get him to ring his mother. i have to initiate a visit to our sons,,he does not seem to think about him too often. not really aware of stuff going on round him,,a bit blinkered. SO,whats going on ?,could this be a start to a form of dementia ? He is diabetic type 2,,and at first,i thought ,these strange lapses were blood sugar problems,but i suspect something a little more now. This is not a "nag",as i care for him,but am finding it harder and harder,to make sense of things and situations. He wont go to doc's....i cant broach the subject,as he would not understand....oh,and he wont take responsibility for anything. he seems ok,in his own skin,drifting along,in a world of tv and films,and not much else...it is me,who finds herself,more and more alone,and lonely. experts ?
