What is the Origin of Anxiety Pathophysiology?

The term originates from medical science, combining "anxiety," a psychological state of excessive worry, and "pathophysiology," which is the study of how disease processes affect normal body function. Its clinical relevance lies within psychiatry, neurology, and increasingly, endocrinology due to the profound role of stress hormones.

What is the Mechanism of Anxiety Pathophysiology?

Pathophysiology frequently centers on hyperactivity in the amygdala, the brain's fear center, and an imbalance in key neurotransmitters such as serotonin, GABA, and norepinephrine. Chronic stress leads to dysregulation of the Hypothalamic-Pituitary-Adrenal (HPA) axis, resulting in altered cortisol secretion patterns and heightened physiological arousal. This hormonal and neural dysregulation sustains the state of vigilance and worry characteristic of clinical anxiety.

Anxiety Pathophysiology

Meaning

Anxiety pathophysiology refers to the disordered physiological and neurobiological processes that underlie the clinical manifestation of anxiety disorders. This condition involves a complex, dysregulated interplay between the central nervous system, the autonomic nervous system, and the endocrine system. Understanding the biological basis provides a pathway for targeted clinical intervention to restore neuroendocrine balance.
