Okay, you are opening my eyes to more areas of discussion. My husband started having PD symptoms 14 years ago. He is totally unmedicated (won't see a doctor) and his symptoms are slowly getting worse. I had never heard of the Pisa syndrome, but it perfectly describes what he does. He won't sit at the table for meals, but sits on the couch. I prop pillows on his right side to help him sit up straighter, but now he leans to the right and so far forward that I think he's going to fall on the floor. He has started asking me to feed him because food starts falling out of his bowl, so I push him up with one hand and feed him with the other. I bet I look comical at best.
One last thing, He has developed a nervous giggle. He has never been one to show his feelings (we've been married 50 years) so now it seems really strange to hear him giggle or cry over almost everything, including TV commercials.
People outside our PD community can't possibly understand. Thanks for listening.
