When Your Child Is a Psychopath

Researchers believe that two paths can lead to psychopathy: one dominated by nature, the other by nurture. For some children, their environment—growing up in poverty, living with abusive parents, fending for themselves in dangerous neighborhoods—can turn them violent and coldhearted. These kids aren’t born callous and unemotional; many experts suggest that if they’re given a reprieve from their environment, they can be pulled back from psychopathy’s edge.
But other children display callous and unemotional traits even though they are raised by loving parents in safe neighborhoods. Large studies in the United Kingdom and elsewhere have found that this early-onset condition is highly hereditary, hardwired in the brain—and especially difficult to treat. “We’d like to think a mother and father’s love can turn everything around,” Raine says. “But there are times where parents are doing the very best they can, but the kid—even from the get-go—is just a bad kid.”
We have a fairly good idea of what an adult psychopathic brain looks like, thanks in part to Kiehl’s work. He has scanned the brains of hundreds of inmates at maximum-security prisons and chronicled the neural differences between average violent convicts and psychopaths. Broadly speaking, Kiehl and others believe that the psychopathic brain has at least two neural abnormalities—and that these same differences likely also occur in the brains of callous children.
The first abnormality appears in the limbic system, the set of brain structures involved in, among other things, processing emotions. In a psychopath’s brain, this area contains less gray matter. “It’s like a weaker muscle,” Kiehl says. A psychopath may understand, intellectually, that what he is doing is wrong, but he doesn’t feel it. “Psychopaths know the words but not the music” is how Kiehl describes it. “They just don’t have the same circuitry.”
