What Nadine Burke Harris's video and Bruce Perry's book "The Boy Who Was Raised as a Dog" have in common is their public health and medical backgrounds, allowing them to speak on the physiological effects that the neurological changes that childhood trauma can cause. The relationship of the brain-body connection is one that highly fascinates me, and I actually found Perry's style of writing so accessible, a great blend of narratives and neuroscience, that I read the entire book before this summer session even started.
In her video, Nadine Burke Harris discusses a patient of hers named Diego who was physically smaller than a child should developmentally be at his age, and how his stunted growth was as a result of the biochemical changes that occurred as a result of enduring adverse childhood experiences.
Perry discusses this "failure to thrive" (the field of medicine should really come up with a less stigmatizing name for that) as seen in many of his other patients and chapters within his book. I find this really interesting from a scientific perspective, and even more interesting that the lack of development resulting from trauma can be tangibly seen on brain scans, as well as the improvement of child brain development after treatment and intervention, namely, being raised in a safe and stable home.
