With virtually unlimited information at every practitioner's fingertips, therapists are expected to adapt to a world of increasing complexity, one in which they must address the "whole person" of each client. But this new "era of information" needs to be integrated and made manageable. In this single-volume learning resource, seasoned psychotherapists Richard Hill and Matthew Dahlitz introduce practitioners to the many elements that create our psychology. The book opens by delving into the biology of our brains-including neurons, brain networks, and emotions-as well as the biology of our bodies, from the "brains" in our body to the vagus nerve, biofeedback, and the gut-brain connection, The world of genetics is explored through gene expression, cell mutations, epigenetics, and the genetic basis for brain dysfunction. Regularly treated disorders are addressed-affective, trauma, and behavioral disorders-as well as the less usual but potentially confronting, such as schizophrenia, PANDAS, and neurodevelopmental disorders. It also discusses anxiety and OCD; memory reconsolidation; somatic therapy; trauma therapy; and addiction and recovery. Finally, the book explores innovations for the twenty-first century therapist, revealing what is emerging now in the field. Book jacket.
