What is the Origin of Cortisol Dysregulation Mapping?

The concept evolved from the foundational endocrinology of stress response, which established the HPA axis as the primary regulator of cortisol secretion. Clinical practice adopted diurnal sampling techniques to capture the pulsatile and circadian nature of glucocorticoid release, which is a more accurate reflection of physiological status than a single serum test. This mapping provides the dynamic context necessary for effective clinical interpretation and intervention.

What is the Mechanism of Cortisol Dysregulation Mapping?

The assessment quantifies the downstream effects of central nervous system signals on the adrenal cortex, detailing the feedback loops between the hypothalamus, pituitary gland, and adrenal glands. Dysregulation manifests as inappropriate timing or magnitude of cortisol release, which can lead to chronic activation of glucocorticoid receptors. These sustained or aberrant signals disrupt metabolic, immune, and sleep-wake cycles, necessitating targeted correction of the HPA axis.

Cortisol Dysregulation Mapping

Meaning

This clinical procedure involves the systematic measurement of cortisol and its metabolites across a 24-hour period to precisely characterize abnormalities in the hypothalamic-pituitary-adrenal (HPA) axis function. The goal is to identify deviations from the expected diurnal rhythm, such as a flattened curve or inverted rhythm, rather than relying solely on a single, static measurement. Mapping helps differentiate between various forms of chronic stress adaptation and adrenal insufficiency.
