Hi Pah,
My Husband's driving became a problem in that he would take hours to get to a destination, that should have taken 30mins, he would get totally lost. Then his reasoning became affected and he would pull out in front of other cars, but the worst one was when he pulled out in front of a huge articulated lorry, on the top of a hill, and nearly killed us both.
His reaction to the driver who was swearing and blowing his horn, "it was only because I'd got the gears stuck!!"
He had not looked in his mirror, he could not reason why he should look in his mirror.
The outcome was that he wasn't allowed to drive anymore, and it was my fault for telling his doctor, he was furious at being stopped from driving, but at least nobody has suffered, and nobody has been killed!
Eventually he resigned himself to the fact that he would never drive again, and gave his car to our daughter.
We were also told that no insurance company would cover a driver with Alzheimers.
And that's what this disease does isn't it? it takes and takes and takes, and rarely gives back if at all.
But when it does give back, a smile, a laugh or a memory, it was worth taking the car away.
Best Wishes
Cjay
PS sorry but I know this doesn't help how your husband is feeling at the moment.
