@yorkie46 after my husband died, I was discussing his illness with my gp, and I explained to her that although he was diagnosed seven years before he died, and I had known he had Dementia for at least three years before he was diagnosed, in actual fact, looking back over our 21 years of marriage, I would say there were, at most, maybe three years that weren't influenced by what I would describe now as a sort of "creeping dementia" or pre dementia. Slowly, there was increasing paranoia, so slowly you didn't really notice for years, because he used to make a big joke about it. The very slowly increasing control over every aspect of our lives. Desperate not to offend anyone, so we had to appear to be whatever he thought others expected us to be. The perfect family. So desperate not to attract attention by not having everything under control, he couldn't see that the bullying behaviour itself was not normal. My doctor was very interested, particularly in the fact that as my husband's illness progressed and he forgot to mind what others thought, his real, sweet personality shone through. Medication helped a lot with getting him over the paranoia too. But, as the doctor said, how, without the benefit of hindsight, can you make the call between what's a symptom that needs investigation, and what's just bad behaviour?
