My husband was recently diagnosed with MCI/early stage dementia. He is 72 years old and has type 2 diabetes and high blood pressure and is morbidly obese. I am concerned about a change in behavior, ie: he has recently begun watching/listening to pron movies on television. This is totally out of character for him. He doesn t seem to become involved in what he is seeing. It s just there. He is otherwise, to people outside the home, functioning appropriately though sometimes a bit sluggishly. Is this kind of change to be expected?
