My dad had a stroke 14 yrs ago and had some dementia from it, but when he fell in July and fractured his nose along with 4 other places around his eye, I believe it made his dementia worse. Anyway he goes through the mood swings and drives down the middle of the road or hugs the line when there is other traffic. He just got his license renewed and and I was praying he wouldn't pass the eye test, but two people and three tries and they gave him his license. I'm ready to put a helmet on to drive because the license place is telling me they help a lot of people like that. I don't think he's safe to drive. He really had problems with the side lights. They moved the machine away and showed him where the lights would be and then still coached him when to look for them. I was really upset by the time we left.
