Hi all. About eight weeks ago I had a case of Benign Fasciculation Syndrome
that set in about a day or so after some moderate irrational fear of NMD. At that point my Anxiety went from moderate to fantastic.
I saw a GP and a Neurologist who diagnosed me with 'Just Anxiety', and then I'm seeing a Psychiatrist (three visits thus far) who gave me Xanax (down to .125mg per day) and Seroquel (up to 150 mg/day). I've also started taking St. John's Wort under his supervision (though not necessarily with his blessing)
Today, both the Anxiety and the BFS is much improved, but not gone, though I wonder if seeing the Neurologist and getting a clean bill of health is not as responsible as any treatment for my improvement.
One possible side effect that my GF has started noticing is occasional bouts of Peripheral Limb Movement Syndrome-like effects while sleeping. She says it starts with my feet and progresses into my calves, thighs, and buttocks until my shoulders get in on the act. (For what it's worth I've also been having vivid dreams, the last of which I usually recall, and many of them are 'laced' with a dose of anxiety.)
So I saw the movie Awakenings
(1990) the other day, where Robin Williams' character speculates that Encepholitis Lethargica, a condition that left patients in an indefinite catatonic state, was actually similar to a Parkinsonian Disorder taken to the extreme where all the extra movements manifest as no movement at all.
As anyone who saw the movie knows (SPOILER ALERT), he treated them with L-Dopa, a dopamine agonist used to treat Parkinson's, and they briefly awakened. As the treatment began to lose it's effect the patient (Robert Deniro) began experiencing paranoia, akesthesia, worsening 'nervous tics' (Deniro's character described himself as a collection of tics), and eventually the catatonia returned.
This got me thinking about Seroquel and my PLMS-like symptoms. Seroquel is a dopamine antagonist, basically the opposite of what Deniro's character got, and Seroquel is known to cause RLS. RLS patients often suffer from PLMD, and dopamine agonists are used to treat both.
Last night I even began having hypnic jerks which delayed my sleep for the first time since treatment, and I do believe my feet felt restless.This got me thinking: Is a Dopamine Antagonist like Seroquel possibly a bad choice in treatment for someone like me, who's Anxiety was primarily triggered by Benign Fasciculations? If I am to believe that they were caused at least in part by Anxiety, then isn't this an involuntary movement of pyschological origin? Don't all antipsychotics like Seroquel list Involuntary Movements and / or Akesthesia as possible side effects?
Is it possible that the Fasciculations would have subsided had I taken a dopamine agonist plus an SSRI, or at least not taken Seroquel.
It's not that I mind the Seroquel. It helps my appetite, it helps me sleep every night but last, and I find it pleasantly sedating... I'm just wondering aloud about Dopamine and all forms of Myoclonus.
