Individualism has been a constant theme of the development of child and adolescent mental health since at least 1870.  Freud’s Scientific Project (1895) is an exercise in neurological individualism as have been many subsequent neuroscience projects.  Just because bodies contain neurological and chemical circuits, it does not mean that mammalian animals are discrete.  Mammals live in communication networks and humans have evolved to make those networks linguistic.  It is species adaptations that are manifest in the lives of single members of a species and provide for fitness to environment.  The many biological scientists that call themselves neurologists have been prone to misunderstand this Darwinian premise.  The convenience of regarding separate bodies as the focus of both evolution and treatment belies understanding of survival of the fittest.  We always treat the patient with words, even while we might target particular chemical and neurological phenomena.
