Anxiety Disorders
Anxiety Disorders (DSM-5-TR)
Excessive worry, fear, or avoidance that interferes with daily functioning. Includes generalized anxiety (GAD), panic disorder, social anxiety, specific phobias, and agoraphobia. Anxiety disorders are the most prevalent class of mental disorders worldwide.
Prevalence: ~19% of US adults in any given year; ~31% lifetime
Clinical Picture
Anxiety disorders share a common thread — the overestimation of threat and the underestimation of one's capacity to cope — but they diverge significantly in their clinical presentation and optimal treatment. Panic disorder responds dramatically to interoceptive exposure and cognitive restructuring of catastrophic misappraisals. Generalized anxiety, with its diffuse, free-floating quality, often requires attention to the underlying intolerance of uncertainty. Social anxiety involves both cognitive distortions and deep shame that may have developmental roots. The anxious client who can name their fear is in a different clinical situation than the one whose anxiety is 'about everything and nothing.'
Treatment Considerations
Exposure-based interventions have the strongest evidence base across anxiety disorders, but the form of exposure matters. For clients with significant avoidance, behavioral approaches (graduated exposure, response prevention) are often the most efficient starting point. For clients whose anxiety is embedded in relational patterns or existential concerns, the anxiety itself may be a signal worth listening to rather than a symptom to extinguish. Somatic approaches are particularly useful when anxiety manifests primarily in the body — racing heart, chest tightness, gastrointestinal distress — and the client struggles to access cognitive interventions while activated.
