Should he be driving? Is he suffering from dementia? (Are YOU suffering from his dementia?)

Best wishes.

My siblings and I have this joke: we'd take away his keys but he'd go out and buy another car.

He's a stubborn old cuss, that's all.

As for the senility, don't know. No diagnosis and he'll never agree to an evaluation. And he may not even be senile really, just suffering from really bad judgment and stubbornness.

My father, who passed at 98, saw a physician regularly (few times a year.) So do I.

Not talking about 'senility,' but dementia, which is on the 'spectrum,' but not senility.

Dad's a retired doctor himself and self-prescribes and I'm certain that he doesn't tell his PC about the other drugs. Meanwhile, the PC renews his other prescriptions.

And I'm certain Dad hasn't seen an ophthalmologist (eye doctor) in a long time. He uses those $6 glasses from the drugstore (magnifying glasses with a noserest). My guess is that if the eye doctor thinks that his vision prevents safe driving, he has to report that to the Division of Motor Vehicles and Dad will lose his license.

Another way Dad avoids being mentally evaluated is to evade his doctor.

It's important to think about the lives he might take if he hits someone else. And that's a real possibility.
