Mechanisms Of Physical And Emotional Stress Advances In Experimental Medicine And Biology 245

Nutrients, Stress and Medical Disorders

A benchmark survey of current clinical findings on the complex interactions between diet, stress, and mental health, and their impact on disease states. The authors give special attention to the influence of stress on physical health, mental health, and cognitive function, including the critical effects of maternal nutritional status and stress levels on fetal physical and mental development, the role of lipids in the development and treatment of depression, the role of fish oil in the development of aggressive behaviors, and the consequences of obesity on stress and the development of eating disorders. Additional chapters examine the effects of stress on chronic disorders, women, and cardiac function, and the influence of inflammation on diet, neurological functions, disease incidence, and cognitive functions.

Mechanisms of Physical and Emotional Stress

It has been over 50 years since Hans Selye formulated his concept of stress. This came after the isolation of epinephrine and norepinephrine and after the sympathetic system was associated with Walter Cannon's "fight or flight" response. The intervening years have witnessed a number of dis coveries that have furthered our understanding of the mechanisms of the stress response. The isolation, identification and manufacture of gluco corticoids, the identification and synthesis of ACTH and vasopressin, and the demonstration of hypothalamic regulation of ACTH secretion were pivotal discoveries. The recent identification and synthesis of CRR by Willie Vale and his colleagues gave new impetus to stress research. Several new concepts of stress have developed as a result of advances in bench research. These include the concept of an integrated "stress sys tem", the realization that there are bi-directional effects between stress and the immune system, the suggestion that a number of common psychiatric disorders represent dysregulation of systems responding to stress, and the epidemiologic association of stress with the major scourges of humanity.
