This chapter summarizes the main brief therapies and reviews the potential of neurological growth and repair that exists within each of them. Eye movement desensitization and reprocessing (EMDR) is probably one of the most effective methods, within the brief therapies, of enabling neurological repair and reprocessing in attachment and related disorders. There is a substantial evidence base of the effectiveness of EMDR in post traumatic stress disorder arising from early trauma and attachment difficulties. Childhood trauma and attachment patterns are held within the right hemisphere of the brain, which is the centre for emotional connections, image forming symbolism, meaning, and non-cognitive processes. CBT focuses on the conscious experience of meaning making. CBT may also work by using cognitive structures to manage anxiety states and an increase in stimulation of the parasympathetic arousal response. Neurolinguistic psychotherapy is an outcome-orientated psychotherapy that works with the neurolinguistic reality of a client’s subjective experience of the world.
