The most interesting aspect of this research to me as a practitioner, is that there is a general increase in genetic degradations that can not be attributed to hereditary, per se. From a historical perspective and from what I see in classroom and therapeutic settings, there a general decline in the neurological systems of the children that we are producing--leading to a broad spectrum of disorders that include learning disabilities, sensory-processing disorders, attention deficit disorders, autism, Asberger Syndrome and psychiatric disorders. Most have co-morbid symptoms or factors and can include deficits in the functions of organ systems throughout the body. De novo mutations are the most likely cause of this spectrum of neurological deficits. Rosko's comment about regarding the organism as an ecosystem is on point.
