Neuroscience in the court, too late, too
early on time?
Dr. Gur, enthusiastic to say the least, gave a very
interesting presentation of how neuroscience is presented in the courtroom.
Although much of Dr. Gur’s presentation was a review to those in the room, it
was clear that this man was passionate about neuroscience. In the midst of his
talk however he may have overlooked answering the question he posed at the
beginning of his lecture through design or error this open ended presentation
gave me the opportunity to discuss it in a variety of ways.
In Dr. Gur’s career he has diagnosed a few patients but
most notably was the infamous letter bomber who Dr. Gur concluded suffered from
schizophrenia. But what drives a person to become a serial killer or a psychopath
and how can we catch it. More importantly once we do catch it, what exactly do
we do with this knowledge? Many believe that psychopathy is a genetic disorder
that could possibly be detected almost as easily as Autism. But once we have
this information do we end the problem at the source or do we take the chance
and see how the child turns out; it is hard to tackle the question without
falling into eugenic like practices.
So you say your child is a psychopath?
In an article by Jennifer Kahn in the New York
Times entitled “Can You Call a 9-Year-Old a Psychopath?” we track the
development and symptoms of Michael who after a battery of tests and
misdiagnosis is believed to be a child psychopath. Michael’s mood often turns
on a dime and his response to irritating stimuli is eccentric and violent but
very goal oriented. The article discusses other examples of child
psychopathology emphasizing the apparent lack of empathy and fear of
repercussions. In theory we can observe the brains of these children and see
deficiencies in the amygdala and other related areas of the brain that cause
the children to exhibit an absence of empathy. However no official diagnosis is
available for childhood psychopathy because it is not easy to distinguish
developing brains from those of mentally ill patients and even harder to
distinguish between questionable behaviors in adolescences.
So what is next?
First off it is important to note that psychopathy
in children does not exist what does exist is referred to as “callous-unemotional”
and although not full blown psychopaths they do exhibit characteristics like a
lack of affect, remorse or empathy which puts them at risk for becoming
psychopaths and had been determined to be 80% heritable. But the question still remains how can we help
these children develop into functioning members of society? Dan Waschbusch, a
researcher at Florida International University, has dedicated the last 10 years
of his life to understanding the patterns of development in callous-unemotional
children. He hopes that treatment could be used to help these children avoid
becoming psychopaths. Researchers have linked these abnormal behaviors to low
levels of cortisol and amygdala deficiencies, as well as deformities in the
portion of the brain that are responsible for fear and shame. “The desire to
avoid those unpleasant feelings, Waschbusch notes, is part of what motivates
young children to behave.” These
children however do not feel this remorse and so act very manipulatively
without consideration for others wellbeing and this is what makes them
extremely difficult to treat.
Callous-unemotional children respond to treatment
much like sociopaths do, in that they do not take punishment well but show
signs of improvement if rewards are given for good behavior. However the
tendency to manipulate the system is high and often actions escalate in a
premeditated fashion if the child decides to not participate any longer. So
although no clear method for treating these at risk children exists Waschbusch
states that “People are worried about labeling, but if we can identify these
kids, at least we have a chance to help them...And if we miss that chance, we
might not get another one.” However much like other researchers he believes
that developing treatments for these children is possible and considering that
C.U. children have a 50/50 shot of developing into full blown psychopaths some
sort of treatment is a must. Frick another
researcher believes “If treatment is begun early enough… it may be possible to
rewire the brain so that even C.U. children might develop greater empathy”.
Considering the plasticity of the developing brain it seems likely that
environmental influences like “ warm, affectionate parenting seems to reduce
callousness in C.U. kids over time”

I found it very interesting to note that psychopathy in children does not exist. The term “callous-unemotional” doesn't seem much better. The idea of stopping the problem before it starts is particularly compelling. If we can identify these kids we absolutely can treat them. Perhaps it will even become evident if there are external factors that can either help or hinder the problem. How much is this effected by genetics and or environmental factors?
