Thanks Paula:

For your very informative reply. Yes, I do have symptoms...a tremor in my left hand and arm, but it isn't always there. There are times in the morning, usually after first getting up, when the tremor is missing. It's also missing when I'm working on a manuscript; i.e. my mind is elsewhere.

I do have PD though but it sometimes has a mind of its own.

Thanks again for the explanation. It is much appreciated

All the best,

Lloyd
