The study of the effects of gonadal hormones in the brain focussed mainly on reproductive actions for a long time. Meanwhile, however, it is well known that gonadal hormones, in particular estrogens, also have neuroprotective and psychoprotective properties. They modulate many brain functions such as cognitive functions, pain regulation, motor coordination, and epilepsy, as well as affective and psychotic disorders, to name just a few. In fact, during the past few years we have experienced a major change in our understanding of the endocrinologic aspects of psychiatric disorders. Endocrinologic irregularities in psychiatric patients are no longer viewed as pure epiphenomena but rather discussed as part of the pathomechanism of the disorders. How exactly estrogens affect various disorders is a fascinating and intriguing aspect of this emerging field of non-reproductive brain actions of gonadal hormones. Among the estrogens, especially estradiol appears to play an important and multimodal role in the brain. Which of estradiol s many membrane, intracellular, and genomic actions matters most in psychiatric disorders, remains to be discovered. The aim of this volume is to summarize the role estrogens play in major psychiatric disorders, such as schizophrenia, depression, and dementia, and to provide a state-of-the-art overview of current knowledge, but also of questions that are still open. It is intended to be a resource for clinicians and readers who are interested in contemporary research developments in this field.

This book addresses key issues in perinatal mental health and discusses the different types of psychiatric care that may be appropriate for pregnant women, parents and infants, with emphasis on the need for joint care. The wide range of preventive measures, mainly applicable in primary care and the various potential curative interventions are examined in detail, with coverage of ambulatory care, day care and the role of mother and baby units. The importance of working in networks and joint decision-making strategies is explained. In addition, an overview of maternal perinatal psychopathology is provided and other relevant aspects are fully discussed, including the establishment of parent-infant interactions and the impacts of parental psychiatric illness on parenting skills and infant development. The book will be invaluable for adult and child psychiatrists, psychologists, psychotherapists, midwives, nurses and all others involved in the provision of perinatal psychiatric care.

A number of studies, mostly focusing on estrogen replacement therapy in women, have reported beneficial actions of these hormones on various neurobiological and neuropathological parameters in health and disease. Recent research has focused on gender differences and there is increasing evidence that estrogens exert protective effects in schizophrenia. Hormonal fluctuations or lack of estrogen may increase the risk of depression among vulnerable women. Treatment of depression with estrogen may stabilize and restore disrupted homeostasis - as during post-partum, premenstrual, or perimenopausal conditions - and act as a psychomodulator to offset vulnerability to dysphoric mood when estrogen levels are significantly decreased, as in the case of postmenopausal women. Studies on the effect of estrogens on Alzheimer's Disease are still rather controversial, they do, however, facilitate the hypothesis that estrogens may have a modifying effect on the onset and course of AD, at least in subgroups of patients.
