Maria's Mom said...
I'm pondering whether my daughter has a new exposure to Lyme or whether she has been dealing with it for a while. She has tried several medicines for her anxiety disorder with multiple instances of side effects that led to her needing to stop the medicine. The most unusual side effect was myoclonic jerks (I think), periodic involuntary movements that were frightening to observe. They resolved when she changed medicines.
My doctoral training (PhD in Education, so no medical training) reinforces that correlation does not mean causation. Is it possible that Lyme impacted her reaction to anxiety/depression meds and contributed to side effects? I'm thinking I should get her records from her psychiatrist and bring them to Monday's appointment the the LLMD's office.
On the same note, Maria had a positive IgM reaction, but no IgG reaction. Does that mean equivocally that she has a recent exposure? Or is this lab result possible even with a long-term exposure?
She has a couple of other strange symptoms -- one was her likelihood of chewing the inside of her cheek. I mentioned that and she replied, "I've been doing that for years." I'm wondering if she may have been infected with Lyme years ago?
How relevant is it to treatment to decide if she has an acute or a chronic infection?
So many questions. So much gratefulness for this forum.

With most diseases IgM shows up first and within weeks it converts to IgG - to show a past infection.
With Lyme disease, IgM can continue to be positive for many months/years.
From Dr. J's website:
"In virtually all infections, the IgM class of antibody (immunoglobulin) appears first and therefore represents a marker for an early infection. In most immune models, the IgM antibody gives way to the well-known IgG antibody class, usually regarded as the major enduring antibody response in chronic infectious diseases or other immune models. In almost all infection models, after just a few weeks, the IgM antibody level wanes to the point of being non-detectable and does not recur. However, a confounding fact in Bb infections is that the IgM antibody may persist for years, a very unusual situation in most disease states. Logically, one would have to conclude that this reflects an ongoing reactivation or persisting and continually renewing infectious state of Bb infection. Most active diagnostic laboratories involved with LD tend to agree with this notion. "
