Some five years ago I started an internet survey on symptoms people with Parkinson’s disease suffer from. More than a thousand respondents answered the call to fill in the answers to 127 questions. I’m still processing the results and expect to be finished by the end of this year.
I think I booked some startling results but I’m not always so sure about their significance. In a* previous posting I did, about a method to optimise medication, I used what I called Biomarkers. I found one of these markers by comparing the average results of respondents who were positive on this marker, and those who were not.
One of the most striking Biomarkers is the quivering of one’s tongue. Patients who have a quivering tongue sometimes, are:
- almost exclusively affected on the right side.
- Have a diminished spatial sense
While people who don’t have a quivering tongue often have thyroid problems.

What do you think?
