cletus, thanks for taking the time to look over my links and do your homework, and raising the tone of the discourse. You make some good points.
You’re right, we don’t know what this kid really has. We have too little data to figure it out. So we cannot know what she has. But we can probably narrow it down to a number of disease.
She’s pre-adolescent, and she is reported to have had a high fever when she was younger (the latter is a bit of a red herring; few children make it thru childhood without having a fever of 105 or so, and do ok). She’s also said to have cerebral palsy. As for CP, I’d not place a lot of reliance on a precise diagnosis, given the lack of testing. But it tells us some things at least.
So what disorders cause such severe self-mutilation in a young child? This is not the pattern one sees in adolescents, neither from frank psychosis nor depression.
1)Mental retardation is big on the list. This could fit in with a cerebral palsy picture too. It’s common for MR sufferers for do autophagia (eating of oneself).
2)Lesch Nyhan is still on my list, despite the kid’s gender. We don’t know how she acts towards others, but the commonest inappropriate behavior with Lesch Nyhan remains self-mutilation.
3)Encephalitis can acutely cause this behavior, but since she’s chronic, this wouldn’t apply. She could have experienced brain damage in the past from her encephalitis, however.
4)Tourette’s Syndrome. Less common here, at least with the finger mutilation. Many tourette’s sufferers chew their lips to the point where damage is severe. But still it possibly could be her underlying problem.
5)Autism. Autophagia has been described not infrequently with autistics.
6)De Lange Syndrome. Possible, they self-mutilate a lot. Another genetic disorder, which occurs equally in males and females.
7)Obsessive-compulsive disorder. Unusual to manifest so strongly and severely at such a young age, but certainly possible. OCD types have chewed off lips, fingers, and even toes before.
I’m sure I’ve left out a few, but we’ve covered the possibilities pretty well with the above, IMHO.
Now if one investigates the above disease entities (which I have) and focuses on suggested therapies for curbing the self-mutilating behavior, one sees a common thread. All the self-mutilating behavior is a mechanism for reducing stress for the individual. The sufferers, when stressed, engage in more self-mutilation. When not stressed, less such behavior is observed.
In terms of therapies, a variety of methods have also been studied. And they are nearly universal in demonstrating that negative reinforcement either has no effect on reducing the undesired behavior, or (the more common finding) it increases the undesired behavior.
So employing negative reinforcement schemes (whether physical or other punishment) should be avoided, as it does not contribute to the goal of reducing the behavior.
What does work? Frankly, and quite unfortunately, not a lot. But positive reinforcement and protective measures demonstrably have the best track record for changing behavior. Unfortunately, many children who engage in this sort of behavior are too cognitively damaged to get as much benefit as we’d like.
Sadly, most of these kids are not responsive to the milder anti-anxiety medications or anti-OCD drugs. If they can engage with a therapist in a behavioral modification program (learn to ask for help, or do distractive techniques when the urge to self-mutilate comes on) along with medications, there is a higher success rate. But frankly the behavior, even in high-functioning kids, can be so automatic that the child will not even notice what they’re doing until they’re well into it.
So in the hard cases, heavy-duty drugs and restraints end up being used. And don’t presume my ignorance on the horrors of the use of restraints. I worked in a chronic psychiatric “hospital” (D building, Baltimore City Hospital) before they were emptied out! They housed both kids and adults.
In short, I continue to assert that negative reinforcement will not be effective in these types of situations. You continue to assert that it will be effective. In higher functioning children, they are already appalled at what they’re doing to themselves, they’re ashamed and frightened and angry to begin with. Punishing them increases the shame and anger, which then causes more self-mutilatory behavior. In lower functioning children, they have trouble making the association between the mutilation and the punishment, which increases their stress, so they do more mutilation. And in OCD, the DSM-IV considers negative reinforcement to be the driving mechanism behind the compulsive behavior.
If you still hold that negative reinforcement is an appropriate approach for these cases, I would like to hear what sort of treatment plan you propose which would help, rather than hurt the situation.
