Once again I must apologize to the newsgroup for my poor spelling/poor
memory for technical terms. There is a disorder, "Lesch Neihans" (just
looking at it I think looks farther from correct spelling than I
thought it would be!) which involves self-biting, especially when uric
acid blood levels are high (it is a--perhaps genetic?--metabolic
This case sounds less extreme than examples of that condition I have
read of, but conceivably one could have milder expressions at one end
of a "spectrum" of this basic disorder.
Irt may, of course, be something entirely different. I believe L.N.
patients bite themselves more for self-stimulation than for expression
of anger. Early in my career (as an intern), I worked with patients
with various self-injurious behaviors, in a Behavior Therapy unit.
We were not so successful with a patient who was equally ready to hurt
others as to hurt herself, but very successful with one who just hurt
herself. She came to us with self-inflicted cigarette burns all over
her arms, almost no hair on her head, and many scars on her face (most
from putting it through a glass door, deliberately), and we interrupted
this behavior long enough for wounds to heal and hair to grow back.
In those days, one could control patients' behavior by giving or
witholding cigarettes... With these (or tokens which could be
exchanged for them) we first rewarded prompt compliance to a command to
sit--wherever she was, on the floor if no chair was right there. When
this became reliable, almost automatic, it could be used to interrupt
self-injurious behavior the moment we saw it. Eventually, she could
work towards accumulating tokens (yes, they could be exchanged for
other things besides cigarettes) earned by number of hours without
On the other hand, might the case described be an expression of OCD?
Are their other aspects of behavior which would fit this diagnosis? OCD
these days is treatable with SSRIs, although (as a speaker at one of my
own conferences reported a few years ago) there is evidence that
cognitive/behavioral therapy for OCD can produce changes in regional
brain metabolism similar to that achieved by SSRI treatment.
