To date, all those reporting a percieved onset of PD after having a thyroid test, did not in fact have a thyroid problem. 2. A symptom of a hypo-active thyroid is lethargy. Sound familliar. Could it be that the thyroid test is in response to the earliest manifestations of bradykinesia. Anecdotally, in my household we believe in spreading things around. My wife has had the thyroid test (and the thyroid problem) and I have the PD. Dennis. ++++++++++++++++++++ Dennis Greene 47/10 [log in to unmask] ++++++++++++++++++++
