Overview

Anxiety is an emotional and physiological state characterised by apprehension, worry, and heightened arousal in anticipation of a perceived threat, accompanied by autonomic changes such as increased heart rate, muscle tension, and elevated cortisol. Adaptive anxiety mobilises attention and behaviour in the face of danger, but when excessive, persistent, or disproportionate it constitutes a clinical anxiety disorder that impairs daily functioning. The anxiety disorders include generalised anxiety, panic, social anxiety, and phobic and related conditions, underpinned by dysregulation of amygdala-prefrontal circuits and neurotransmitter and neuropeptide systems, and frequently comorbid with depression and stress-related disorders. Management spans psychological therapies such as cognitive-behavioural therapy, pharmacotherapy, and complementary and somatosensory interventions. Peer-reviewed work relevant to this topic examines somatosensory stimulation and cortisol response under experimental social stress, the role of cholecystokinin in fear and anxiety, anxiety and depression among nursing students and healthcare staff, photobiomodulation in relation to mood and cognition, early-life pain and persistent anxiety-like behaviour, perinatal mood and anxiety disorders, and death anxiety. These contributions span psychiatry, clinical psychology, and neuroscience, addressing the mechanisms, correlates, and treatment of anxiety across populations and settings, an area in which the journal publishes peer-reviewed research.
