History
The patient is a 64-year-old right-handed white female who presents with her daughter for evaluation of several symptoms. These include balance problems and a tendency to fall backwards, change in her voice and micrographia. They are wondering whether or not she has Parkinson 's disease.

I think she may have just diabetic peripheral neuropathy and maybe she is anxious or she could actually have a bona fide cervical
