This book is concerned with the extent to which childhood stress and trauma lead in relative maturity to major depression (MDD) and post-traumatic stress disorder (PTSD). The loss of synapses in the cortex, accompanying childhood maltreatment, is identified as a principal mechanism for developing these disorders. Considerable attention is given to identifying interventions that will restore lost synapses, so ameliorating these mental illnesses.

Produktbeschreibung
This book is concerned with the extent to which childhood stress and trauma lead in relative maturity to major depression (MDD) and post-traumatic stress disorder (PTSD). The loss of synapses in the cortex, accompanying childhood maltreatment, is identified as a principal mechanism for developing these disorders. Considerable attention is given to identifying interventions that will restore lost synapses, so ameliorating these mental illnesses.

The book describes the emergence of abnormal psychology in youth and adult life following childhood maltreatment. Of considerable immediate concern is the extent to which such maltreatment significantly enhances the tendency to suicide and suicidality. Next, consideration is given as to how personality disorders, such as obsessive-compulsive disorder, the very dangerous borderline personality disorder, and the publicly offensive narcissistic personality disorder, arise from childhood maltreatment. The classification or nosology of mental and personality disorders as well as the principal psychoanalytic approaches available for their treatment are sketched together with recent attempts to use novel constructs that bridge between symptoms (based on patients’ behavior and self-descriptions).

Recently, new techniques have been developed for brain imaging and non-invasive and localized brain stimulation. These show that nodes of the distributed brain network whose malfunction is closely related to major depressive disorders are likely to differ in their importance from patient to patient. Wonderfully, so-called ‘closed-loop’ stimulation techniques are now available for automatically adjusting the activity of individual nodes in individual patients, relieving them of their major depression. The results of our research, and that of others using magnetic resonance imaging of mature patients that have been maltreated as children, have been to identify the nodes that have lost gray matter. We have shown that this is likely due to the loss of synapses in these nodes. Finally, the central question of how synapses may be restored in these nodes to ameliorate major depressive disorders, post-traumatic stress disorder, and suicidality is considered, emphasizing the recent revolutionary discovery that the psychedelic ketamine restores synapses and has a therapeutic effect on mental health.

Autorenporträt
Prof. Maxwell Bennett AO is an Emeritus Professor of Neuroscience and held the first University Chair for ‘research recognized internationally to be of exceptional distinction’ at Sydney University. His over 400 papers are concerned with research on synaptic connections between nerve cells, particularly in the brain related to stress and trauma. Professor Bennett has written twelve books concerned with the history and philosophy of the brain and mind, many with his philosophical colleague Peter Hacker. Among the organizations he has initiated to promote science, brain research, and mental well-being are the Federation of Australian Scientific and Technological Societies (now Science & Technology, Australia), the International Society for Autonomic Neuroscience, and the Tropical Brain and Mind Foundation. Professor Bennett founded the Brain and Mind Research Institute (now Centre) in Sydney 20 years ago and was responsible, more recently, for initiating the Mind and Neuroscience Thompson Institute in Queensland. He is at present Chair of Thompson Brain & Mind Healthcare Ltd.
