NFLPatriotsFan,

Welcome to the forum.

There are a number of structured, but still, ultimately, subjective tests, such as UPDRS, used for Parkinson's.

But, it surprised me too that there was not a collection of objective symptom measuring tools commonly available. As a first step, I wrote one: an online tap test. This can be found at:

or if you want to store your results on a database, go to:

If you are interested in measurement, please get in touch.

It seems to me that many symptoms could be tested from home frequently, with the data being analysed using "big data" techniques.
