Despite marked advances in stress research, confusion as to what stress is continues in the 1990s. Thus, it may be of benefit to briefly mention the definitions of four key concepts related to stress: those of homeostasis, stressor, stress, and adaptive response. 1 Life exists by maintaining a complex dynamic equilibrium, or homeostasis, that is constantly challenged by intrinsic or extrinsic adverse forces or stressors. Stress is, thus, defined as a state of threatened homeostasis, which is reestablished by a complex repertoire of physiologic and behavioral adaptive responses of the organism. The adaptive responses may be inadequate for the reestablishment of homeostasis or excessive and prolonged; in either case a healthy steady state is not attained, and pathology may ensue. With these straightforward definitions, the frequently interchangable use of the terms stress, stressor, and adaptive response will hopefully be avoided.This review focuses on the neuroendocrine infrastructure of the adaptive response to stress and on its concerted effects on behavior, the major endocrine axes, and the gastrointestinal and immune systems. It also discusses the altered regulation or dysregulation of the adaptive responses in various physiologic and pathophysiologic states. These may influence the growth and development of an individual and may define the vulnerability of this individual to endocrine/metabolic/cardiovascular, psychiatric, or immunological disease, with their negative short-or long-term behavioral or physical sequelae. To avoid extensive referencing, several review articles containing many of the original references are included.
