Q: Body Tremor
I was diagnosed with bipolar disorder nearly 2.5yrs ago, I am basically stable.
I believe it started around the age of 14...? Counsellor, then several doctors,
turned me away. ANYways, my real concern here is TREMOR! I noticed a random
tremor in my hands, that occurred in periods of high energy, at the age of 15.
It has gradually worsened over the years, there have been at least 3 occassions
where I physically could not write and had to hand the pen to a friend. I could
not read off my notes during a formal class presentation. I used to be able to
karaoke, and now I develop a major leg tremor. AND, on two occassions over
the last 2 weeks a person has commented "are you cold?" or something similar, as
they noticed I had a brief visible shiver... except that I had no idea I'd had
one!!! And once (two weeks ago) dancing with someone, they kept telling me to
stop "being twitchy" (again, I couldn't tell). So, I am now 24, as these
symptoms worsen more and more, I will p robably wait a 'little' while to
see if the full body tremor persists, and then pursue treatment. Is it possible
I could have Parkinson's instead of, or in addition to, bipolar disorder?? Could
it be something else?
(My previous medications include risperdal, zyprexa, lamictal, can't remember
what else. I have now been on seroquil, lithium, and mirapex for about a year. I
don't believe ANY of these medications has shown any effect on my tremors,
positive or negative)
Dear Alex --
Well, this is a little tricky: the tremor might be a separate condition, e.g.
something that's ususally called "benign essential tremor" or "benign familial
tremor", which means "we don't know what's causing it but it we don't see any
reason for concern over the long term because we've seen other folks with this
and they don't get worse".
Or it might be associated with medications, more on
that in a moment; or it might be something more concerning, such as the
"Parkinson's" idea -- though Parkinson's at your age might be the least likely
explanation; I'm thinking here of other uncommon neurological conditions that
can cause tremor. At some point, with your psychiatrist's okay, you might want
to see a neurologist for an opinion from that point of view.
As for the medications: lithium can very commonly cause
tremor, so on the list of those you're currently taking it's the most obvious
candidate for examination. But it sounds like you had this tremor-like
phenomenon before lithium, and it looked then just like it looks now? If so,
then obviously lithium is less likely the basis, although sometimes it can make
an underlying tremor worse (particularly when combined with other
tremor-inducing medications like Depakote; I've not seen tremor with Seroquel
very often, but the mirapex could easily ramp things up).
Because you've been on such a range of medications, and
now are doing pretty well, it sounds like, I'm sure there is hesitation, on your
doctor's part and probably yours as well, to go making changes trying to hunt
down the basis of this movement phenomenon. I'd presume your doctor has talked
with you about "tardive dyskinesia", the movement disorder associated with
medications like Zyprexa and risperidone -- and Seroquel. Usually "TD" is
a slow-motion phenomenon, like tongue movements or shoulder movements, kind of a
slow wiggle. But there are cases of other kinds of movement disorders ("dyskinesias")
that show up late in the course of using these medications (that's the "tardive"
part of the name) and therefore TD would also have to be considered as a
potential cause of what you're describing. I rather doubt that's what's going
on, based on your description, but it would have to be considered. A neurologist
could be helpful here as well, as dyskinesias of several types are part of their
But overall, in terms of common causes of this kind of
thing, I'd say medications like lithium and mirapex are statistically the more
likely basis: you could have a propensity for tremor than nearly any medication
which causes tremor could bring out, and have just gone from one medication to
the next, always with some tremor-inducing medication in there, so that you'd
never really see it get much worse or better as medications were changed --
except for this gradual worsening trend. I've seen that in my patients: we could
get away with lithium and Depakote combined for a while, but over time tremor
developed (on the same dose that once did not cause such a problem) and we could
not get it to go away until we lowered or removed medications commonly
associated with tremor. I'm thinking of one fellow in particular whose course
followed that pattern. He is a fine woodcraftsman and is still making cabinets
and such things; once in a while his tremor is a little bothersome but most of
the time it's not there at all, at least not visible to me. He's still taking
Zyprexa but when that was combined with lithium and Depakote, he had a very
severe tremor that made his woodworking impossible.
I hope something in that diatribe will prove to be
useful to you. (In any case, sorry to have to issue the standard warning: don't
go changing any medications without discussing your plan with your doctor,
