Marty, I've never heard of trunkeal dystonia, but I'm also very new to exploring the details of PD. My mom is the patient. Your letter struck a familiar chord. Mom has had a predisposition towards leaning and walking diagonally...for about the same duration as the other symptoms that eventually were identified as PD, such as dragging her foot. I'm glad you wrote. I'm going to mail her a copy of your message and ask her to question her doctor. I'd love to know if you hear anything else about it. Any thing on the internet about it?? Thanks, Linda
