A typical allostatic response has been initiated by a stressor and then continues for the duration of the stressor, in which it shuts off as the stressor has ended. Allostatic load is the accumulation of stressors and maladaptive responses that may result in an extreme state, where the stress response does not terminate. [26]
(A stressor is a chemical or biological agent, environmental condition, external stimulus or an event seen as causing stress to an organism.) Selye initially (c. 1940s) called this the "general adaptation syndrome" (at the time it was also called "Selye's syndrome"), but he later rebaptized it with the simpler term "stress response".

The diathesis-stress model, also known as the vulnerability–stress model, is a psychological theory that attempts to explain a disorder, or its trajectory, as the result of an interaction between a predispositional vulnerability, the diathesis, and stress caused by life experiences.
According to this theory, two distinct forms of cognitive appraisal must occur in order for an individual to feel stress in response to an event; Lazarus called these stages "primary appraisal" and "secondary appraisal". [5] During primary appraisal, an event is interpreted as dangerous to the individual or threatening to their personal goals.
The integrated stress response can be triggered within a cell due to either extrinsic or intrinsic conditions. Extrinsic factors include hypoxia, amino acid deprivation, glucose deprivation, viral infection and presence of oxidants. The main intrinsic factor is endoplasmic reticulum stress due to the accumulation of unfolded proteins.
