Book Description
Estrogens are key modulators of brain regions that mediate learning and memory formation. This regulation has significant translational implications, as estrogens contribute to age-related memory decline and dementia, emotional disorders, addiction, and recovery from brain injury. Although the importance of estrogens for memory formation has been well accepted within the behavioral neuroendocrinology community, it has yet to be fully appreciated by neuroscientists outside of the discipline. Recent National Institutes of Health policies on the inclusion of sex as a biological variable in grant applications will force thousands of researchers to consider hormonal regulation of memory for the first time. However, the majority of these researchers are not trained endocrinologists, and no previous monograph comprehensively encompasses the breadth of basic and clinical research on this subject. Thus, this book provides a vital resource for non-endocrinologists and endocrinologists alike. Estrogens and Memory: Basic Research and Clinical Implications provides a compendium of cutting-edge basic and clinical research describing the ways in which estrogens regulate memory in a variety of species. Chapters are written by leading experts whose work is on the forefront of this exciting field. Three fundamental discussions focus on: effects of estrogens on the hippocampus and other brain regions central to memory, effects of estrogens on memory and related cognitive processes throughout the lifespan, and translational implications of estrogenic regulation of memory for aging and disease.

Book Description
"A book about the influence of estrogens on memory would have been unthinkable as recently as 30 years ago. Although a few small studies in the late 1970's reported a beneficial effect of estrogens on memory in human women (Hackman and Galbraith, 1976; Fedor-Freybergh, 1977), examination of the role of estrogens in memory did not truly capture more widespread attention until the pioneering work of Barbara Sherwin and colleagues in 1988 and beyond. In her initial paper, Sherwin showed that bilateral removal of the ovaries (aka surgical menopause) led to impaired short-term and long-term memory, whereas treatment of surgically menopausal women with estradiol alone, testosterone alone, or estradiol plus testosterone prevented this decline (Sherwin, 1988). As a search for the terms "estrogen" and "memory" in PubMed illustrates, well over 2000 papers have been published on the subject of estrogens and memory in the ensuing decades. The vast majority of these studies have focused on the hippocampus, a bilateral medial temporal lobe structure essential for the formation of episodic memories, particularly those with spatial, contextual, relational, temporal, and recognition components (Olton et al., 1979; Morris et al., 1982; Kim and Fanselow, 1992; Squire, 1992; Cohen and Stackman, 2015; Tonegawa et al., 2015; Eichenbaum, 2017). Although various forms of learning and memory are mediated by numerous brain regions, including the prefrontal cortex, medial temporal lobe cortices, amygdala, striatum, and cerebellum, the hippocampus has received the lion's share of attention due to its central importance for episodic memory formation. Hippocampal damage produces profound retrograde amnesia for facts and events, as well as anterograde amnesia for new information and impairments in spatial navigation (Winocur, 1990; Anagnostaras et al., 2001; Clark et al., 2002; Gilboa et al., 2006). Hippocampal dysfunction in middle-aged and aged subjects is a primary contributor to age-related memory decline (Golumb et al., 1996; Grady et al., 2003; Apostolova et al., 2010; Burke and Barnes, 2010; Small et al., 2011; Yassa et al., 2011), and has also been implicated in the cognitive impairments observed in diseases such as schizophrenia and depression (Small et al., 2011; Nakahara et al., 2018; Santos et al., 2018; Ott et al., 2019). Moreover, the hippocampi of patients with Alzheimer's disease are substantially atrophied and burdened with copious amounts of amyloid plaques and neurofibrillary tangles, the hallmark pathologies of this insidious disease (Hyman et al., 1984; Walsh and Selkoe, 2004; Selkoe and Hardy, 2016). As such, understanding how estrogens influence hippocampal functioning may provide important insights not only about the fundamental neurobiology of memory processes, but also into the etiology of neuropsychiatric and neurodegenerative diseases"--

Book Description
It is well known that the class of steroid hormones known as estrogens have powerful effects on organs related to reproduction such as the uterus and the breast. What is less well known is that estrogens also profoundly modulate brain function and behavior. Estrogens, such as estradiol, can occur in brain as the result of ovarian secretion of the hormone into the blood that then finds its way to the brain. In male vertebrates, the testes secrete androgens, such as testosterone, into the blood and this class of steroid hormones can be converted into estrogens in the brain via the action of the enzyme aromatase which is expressed in the male brain in many species. Finally estradiol can be synthesized de novo from cholesterol as it has been shown in a variety of species that all the enzymes required to synthesize estrogens are expressed in the brain. This book collects chapters by experts in the field that considers, how estradiol is synthesized in the brain and what its effects are on a variety of behaviors. Special attention is paid to the enzyme aromatase that is distributed in discrete regions of the brain and is highly regulated in a sex specific and seasonal specific manner. Recently it has become clear that estrogens can act in the brain at two very different time scales, one is rather long lasting (days to weeks) and involves the modulation of gene transcription by the hormone-receptor complex. A second mode of action is much quicker and involves the action of estrogens on cell membranes that can result in effects on second messenger systems and ultimately behavior within minutes. Thus this book highlights novel views of estrogen action that are still under-appreciated namely that estrogens have significant effects on the male brain and that they can act on two very different times scales. This volume will be of interest to both basic researchers and clinicians interested in the action of estrogens.

Book Description
It is well known that estrogen is "somehow” a protective hormone for various age-related disorders. This book provides a solid knowledge of estrogen’s neuroprotective activities in the brain with a special emphasis on neurodegenerative disorders such as Alzheimer’s Disease. The focus is (1) to describe the biochemical, molecular, and cellular basis of the protective activity of estrogen and (2) to transfer this knowledge into the hospitals by discussing preventive and therapeutic approaches such as estrogen replacement therapy for post-menopausal women. Besides up-to-date information on estrogen and the brain, this book explains in a highly understandable manner molecular and cellular techniques by which basic data have been collected. The reader, which may include the professional specialist as well as the interested non-specialist, will also gain insight into the scientific transfer process of knowledge from basic science to the clinical situation and therefore "from bench to bed”.

Book Description
This book concerns how estrogens are synthesized in the brain and their two modes of action on behavior: a slow process involving gene transcription and a faster action at the cell membrane. The significance of the regulation and distribution of the estrogen synthesizing enzyme aromatase in the brain is also highlighted.

Book Description
A compelling, “fascinating” (Robert Cialdini) defense of hormone replacement therapy, exposing the faulty science behind its fall from prominence and giving women the evidence they need to make informed decisions about their health. Now fully revised and updated. "Estrogen Matters was my antidote to the misinformation surrounding menopause. This book should be the bible for every single person going through menopause.”―Naomi Watts For years, hormone replacement therapy (HRT) was the medically approved way to alleviate menopausal symptoms (ranging from hot flushes to brain fog) and reduce the risk of heart disease, Alzheimer's, and osteoporosis. But when a large study by the Women's Health Initiative (WHI) announced, with national fanfare, that women taking HRT had an increased risk of breast cancer, women were scared off, and the treatment was abandoned. Now, Dr. Bluming, a medical oncologist, and Dr. Tavris, a social psychologist, reveal the true story of the WHI’s efforts to distort their data to exaggerate unsupported claims of estrogen’s harms. Important updates in this edition include: Evidence that demolishes the WHI’s claim that HRT causes breast cancer. A list of the WHI’s retractions of their original scare stories. Updated findings on estrogen’s benefits on heart, brain, bones, and longevity. A critical review of the alternative products and medications being marketed to treat symptoms of menopause. A sobering and revelatory read, Estrogen Matters sets the record straight on estrogen’s benefits, providing a light to guide women through this inevitable phase of life.
