You are welcome! Gerald,
I didn't want to drive everyone into a panic, but I do believe
from what I have read, that viruses could be a contributing factor
to the development of tremors. I have posted an abstract below,
that might not mean anything to any of the members, but it might be
reason enough to bring it to the attention of their physician.
My father was never tested for any viral infections and I don't
see anyone suggesting that he needs to be, but perhaps it will become
part of a standard test in the future for CNS dysfunction.
Best Wishes, Linda Forrest's Mom
PS Its a pretty old article.

Unilateral ataxia following herpes zoster of spinal C4 segment.
Keswani P, Gupta R, Singh KP, Juneja P, Chablani P
Focal lesions of central nervous system are extremely rare following
cutaneous herpes zoster. A 55 year old male developed
cerebellar speech, right sided ataxia and intention tremor, three weeks
after herpes zoster of right spinal C4 segment. Clinical
examination and investigations confirmed a focal vascular lesion in the
midbrain suggestive of granulomatous angiitis which can
cause focal neurological defect after herpes zoster.
