DHEA and the Brain reviews a range of existing studies regarding DHEA administration to animals and humans. Chapter authors evaluate DHEA metabolism in tissues and organs, explore DHEA effects in the liver that may be of importance to the brain, and discuss recent findings regarding how DHEA is made in the brain. New perspectives about the neuroprotective effects of DHEA are presented, as well as insight related to DHEA metabolism in the brain. A number of health benefits have been associated with dehydroepiandrosterone (DHEA), including anti-cancer, anti-osteoporosis, anti-atherosclerosis, anti-diabetes, immuno-stimulating, and memory-enhancing effects. This has prompted millions of people to take this hormone as a daily nutritional supplement. However, there is some concern that prolonged self-administration may result in future health problems, as well as unease about potential side effects due to the production of steroid derivatives in the tissues. Featuring an esteemed panel of contributors, this volume provides an authoritative overview of the research concerning DHEA and the brain. It presents a variety of innovative approaches and ideas for future investigations into the physiological actions of this hormone.

This book provides an up-to-date overview of the role of neurosteroids and neuroactive steroids in the regulation of brain processes and neuropsychiatric disorders. It addresses the neurosteroid function in brain development and plasticity, in both the normal and the pathological brain. It also suggests possible therapeutic approaches to the use of natural occurring or sinthetic neurosteroids. The contributors suggest that neuroactive steroids could have a role in clinical practice.

Changes in food composition and availability have contributed to the dramatic increase in obesity over the past 30-40 years in developed and, increasingly, in developing countries. The modern diet now contains many foods that are rich in saturated fat and refined sugar. People who eat excessive amounts of this diet are not only likely to become overweight, even obese, develop metabolic and cardiovascular diseases, some forms of cancer, but also undergo a more rapid rate of normal age-related cognitive decline and more rapid progression of neurological diseases such as dementia. A central problem is why people persist in consuming this diet in spite of its adverse health effects and when alternative food choices are available. As high fat / high sugar foods are inherently rewarding, eating for pleasure, like taking psychoactive drugs, can modulate reward neurocircuitry, causing changes in responsiveness to reward-predicting stimuli and incentive motivation. Indeed, the excessive ingestion in modern societies and the resulting obesity epidemic may be viewed as a form of food addiction. Thus, a diet high in palatable foods is proposed to impact upon reward systems in the brain, modulating appetitive learning and altering reward thresholds. Impairments in other forms of cognition have been associated with obesity, and these have a rapid onset. The hippocampus appears to be particularly vulnerable to the detrimental effects of high fat and high sugar diets. Recent research has shown that as little as one week of exposure to a high fat, high sugar diet leads to impairments in place but not object recognition memory in the rat. Excess sugar alone had similar effects, and the detrimental effects of diet consumption was linked to increased inflammatory markers in the hippocampus, a critical region involved in memory. Furthermore, obesity-related inflammatory changes have also been described in the human brain that may lead to memory impairments. These memory deficits may contribute to pathological eating behaviour through changes in the amount consumed and timing of eating. The aim of this eBook is to present up-to-date information about the impact of diet and diet-induced obesity on reward driven learning, memory and cognition, encompassing both animal and human literature, and also potential therapeutic targets to attenuate such deficits.

A cancer-related checkup is recommended every 3 years for people aged 20 to 40 and every year for people aged 40 or older. This exam should include health counseling and, depending on a person’s age and gender, might include examinations for cancers of the thyroid, oral cavity, skin, lymph nodes, testes, or ovaries, as well as for some nonmalignant diseases. A high dietary intake of vitamin C has been shown to significantly reduce the risk of death from heart attacks and strokes, as well as all other causes including cancer. Many clinical and experimental studies have clearly demonstrated that stress, personality, attitude, and emotion are etiologic or contributory in suppressing the immune system as well as leading to the development of many diverse diseases. Regular exercise has been demonstrated to provide benefit to individuals with immunodeficiency diseases, particularly through stress alleviation and mood enhancement. HIV-positive individuals had increases in CD4, CD8, and natural killer (NK) cells immediately following aerobic exercise. Melatonin exerts significant anticancer effects, especially against breast cancer. Vitamin E not only improves insulin action, it also exerts a number of beneficial effects when taken at dosages ranging from 400 to 800 IU, which may aid in preventing the long-term complications of diabetes.
