@Buster29, I finally found a geriatrician about a hour's drive from my grandparents' home and it has really made a difference. He really speaks their language. My grandfather had a bad stroke five years ago and isn't easy to understand when he speaks. The doctor was very patient and just let him find the words on his own time. Sometimes I had a feeling their original doctor got a little frustrated when they couldn't remember an important thing about a medication or whatever.
If you have elderly parents or grandparents, I encourage you to seek out a good geriatric doctor, even if you might have to go a little more out of your way for appointments.
