Thanks for your help on the last question I asked, but my dad has gotten worse and has started being delusional. He was driving (yes he is still a good driver) but going to our cousins car lot saying they are suppose to "give" him and all us kids a car..etc. He has started handing out coins to people he meets, says god told him to. We "broke" his car last Friday, had a caregiver stay with him for a few hours and take him around town...etc..he said he didn't want her to come back, that he doesn't need help. He babbles on and on the last week or so.. We have started guardianship proceedings and have also filed for emergency guardianship..this has worsened so quickly, and I can't get him in to a Geriatric Dr. till July. He found what we did to the car and fixed it. He is back on the road and going all over town telling stories and such.. he has a meltdown and gets violent when we mention that we don't want him driving. Its not the driving it's what he does when he gets there too! Can dementia progress this rapidly? I don't feel comfortable leaving him alone in his house all night. Local doctors are a joke, they examined him and said, yes he has dementia, but they were no help! Help!!
