Overview

Anxiety is a psychological and physiological state of apprehension characterized by anticipatory worry, heightened arousal, and bodily symptoms such as increased heart rate, restlessness, and difficulty concentrating. As an adaptive response it mobilizes attention and energy in the face of perceived threat, but when excessive, persistent, or disproportionate it becomes maladaptive and contributes to clinical disorder. Its biology involves fear and threat circuitry, autonomic activation, and neurochemical signaling, including neuropeptides such as cholecystokinin implicated in fear and anxiety, and it frequently co-occurs with depression and stress-related conditions. Research addresses anxiety across the lifespan and in specific contexts, including the perinatal and postpartum period, chronic and life-threatening illness, occupational and caregiving strain, and existential concerns, as well as a range of pharmacological, psychotherapeutic, and complementary interventions. The peer-reviewed studies indexed under this topic examine mechanisms and treatment of anxiety disorders, postpartum mood and anxiety disorders, the role of cholecystokinin in fear and anxiety, anxiety in nursing students, photobiomodulation in depression and anxiety, early-life experience and anxiety-like behavior, somatosensory stimulation to reduce stress-related cortisol and anxiety, burnout and anxiety in healthcare staff, and death anxiety. Together they reflect investigation of the mechanisms, correlates, and management of anxiety across psychological, physiological, and clinical perspectives.
