claimThe 'allostatic state' is a term labeled by Koob and Le Moal (2001) to describe a midway point in the process of stress, occurring when stress has been chronic but has not yet reached the level of full-blown allostatic load.

claimRobust allostatic interventions must have effects on bodily facets of the allostatic state, rather than being limited to cognitions, emotions, or behaviors.

claimHealth is hypothesized to be an allostatic state of optimal anticipatory oscillation, which relates to the state of criticality, defined as a mathematical point of poise between phases on the border between order and disorder.

claimThe PAO (Paradigm of Allostatic Organization) construct of the allostatic state represents the integrated totality of brain-body interactions and optimal anticipatory oscillation, which is potentially a function of the mathematically-defined state of criticality.

claimThe Predictive Allostatic Organization's definition of an 'allostatic state' differs from definitions provided by other investigators, such as Koob and Le Moal (2001).

claimWhite coat hypertension, as described by Pickering et al. (1988), is understood by the Predictive Allostatic Organization as the cardiovascular facet of the allostatic state of anxiety occurring in the presence of a medical authority figure.

referenceThe propositions of the PAO (Predictive Allostatic Optimization) include: change is the norm of nature; the natural environment is complex; realistic modeling of whole-organism behavior requires systematic attention to environmental complexity; the brain's complexity permits optimized engagement with environmental complexity, including anticipatory regulation; the brain serves as the central command for the organism to permit context-sensitive orchestrations of cross-system operations; brain-body communication is the rule; physiological mechanisms can be modeled as the integrated totality of brain-body interactions (the allostatic state); and health and disease exist along a continuum between allostatic optimality and impairment.

claimThe Predictive Allostatic Organization identifies several conditions associated with environmental, social, or perceived stressors as facets of an allostatic state, including irritable bowel syndrome (Mayer et al., 2001), reproductive disturbance (Rooney and Domar, 2018), bronchospasm (Rosenberg et al., 2014), immune dysregulation (Glaser and Kiecolt-Glaser, 2005), chronic pain (Burke et al., 2017), and addictive behaviors (Koob and Schulkin, 2018).

procedureTo classify a brain intervention, one must determine if the objective is to 'push' or clamp the brain toward a specific output parameter (homeostatic) or to support the brain in moving toward a pluripotent and flexible capacity for meeting the needs of changing situations (allostatic).

claimThe PAO framework postulates a spectrum of allostatic states characterized by varying tendencies for optimal anticipatory oscillation: at one end, 'allostatic states of optimality' indicate a dynamic capacity for recalibration associated with positive health; at the other end, 'allostatic states of impairment' indicate rigidification in operational set points and manifest as disease.

claimThe allostatic state represents the integrated totality of brain-body interactions.

claimThe Predictive Allostatic Organization's conception of the allostatic state does not apply exclusively to pathology, nor does it imply that neural effects or stressors are the sole cause of any disorder; instead, it emphasizes the bidirectional influence between system expression and brain functioning.

claimThe Predictive Allostatic Organization conceptualizes the expression of neurally-regulated functioning within a given system as a facet of an allostatic state.

claimDiseases are defined as allostatic states of impaired anticipatory oscillations, which manifest as rigidifications of set points across the brain and body.

referenceKoob and Le Moal (2001) define an allostatic state as a chronic deviation from homeostasis due to psychosocial or environmental stress.

claimThe Predictive Allostatic Organization (PAO) defines an 'allostatic state' as the integrated totality of interactions between the brain and all organ systems, formalizing the recognition that brain-body relationships are the rule rather than the exception.

referenceUnder the Predictive Adaptive Organization (PAO) framework, allostatic load is classified as one example of an impaired allostatic state, also referred to as allostatic impairment.

claimProgressive alterations in allostatic states and prolonged innate immune activation contribute to chronic infection-associated comorbidities, including cardiovascular disease and neuroinflammation.

claimPersistent allostatic states driven by chronic stressors are linked to cancer development.

perspectiveMolecular experiments using cell- and animal-based models are necessary to investigate how chronic stress-induced allostatic state changes mechanistically contribute to tumor initiation and progression, bridging the gap between observational findings and causative biological pathways.

claimMost studies investigating the link between chronic stress and disorders have focused on comparing pre- and post-disease states rather than examining the intermediate adaptive phases, known as allostatic states, that precede disease onset.

claimImmune changes reflect progressive alterations in allostatic states and prolonged innate immune activation, which contribute to chronic infection-associated comorbidities, including cardiovascular disease and neuroinflammation.

claimPersistent allostatic states in the immune system can result in irreversible immune dysregulation and immune system re-programming.

claimThe allostatic state refers to temporary and dynamic physiological deviations that are part of a healthy adaptive process, though prolonged activation of these stress response systems can become maladaptive.

claimAdaptive physiological shifts, or changes in allostatic state, contribute to the development of disorders such as drug addiction, immune diseases, and cancer.

claimChronic drug use drives the human body through a series of dynamic neurobiological transitions—specifically from drug-naive to transition, dependence, and ultimately abstinence—with each stage corresponding to distinct shifts in allostatic state.

claimAn allostatic state occurs when allostasis has been active for a long period, causing physiological mediators to deviate from their normal levels to a new set point that can be higher or lower than the original.

claimBeing in an allostatic state imposes a cost on the body, particularly when chronic stressors prevent the stress response from deactivating.
