Understanding Generalised Anxiety Disorder
What Is GAD?
Generalised Anxiety Disorder (GAD) is a psychiatric condition characterised by excessive, uncontrollable, and persistent worry about a wide range of everyday events or activities. Unlike phobias or panic disorder, the anxiety in GAD is not restricted to specific triggers but is “free-floating.” Classified under DSM-5 (300.02) and ICD-11 (6B00), it often presents with significant physical symptoms, including muscle tension, fatigue, and autonomic hyperactivity.
In a medico-legal context, GAD is frequently assessed following traumatic events (such as road traffic accidents) or chronic workplace stressors. Expert psychiatric evidence is vital to differentiate GAD from transient stress reactions or adjustment disorders, as a formal diagnosis of GAD often indicates a higher level of long-term functional impairment and psychological damage.
Diagnostic Criteria (DSM-5)
A diagnosis of GAD requires the presence of excessive anxiety and worry occurring more days than not for at least six months, involving several events or activities. The individual finds it difficult to control the worry, and the anxiety is associated with at least three of the following six symptoms:
Core Cognitive Symptoms
- Excessive anxiety and worry (apprehensive expectation)
- Difficulty controlling the worry
- Pervasive worry about multiple domains (work, health, finances)
- Marked distress or impairment in social or occupational areas
Physical Arousal Symptoms
- Restlessness or feeling keyed up or on edge
- Being easily fatigued
- Difficulty concentrating or mind going blank
- Irritability
Somatic Manifestations
- Muscle tension and physical aches
- Sleep disturbance (difficulty falling or staying asleep)
- Exaggerated startle response
- Autonomic symptoms (sweating, racing heart, nausea)
Exclusionary Factors
- Disturbance not attributable to physiological effects of a substance
- Disturbance not better explained by another mental disorder
- Anxiety is not focused on a single trigger (e.g., social situations)
Note: In children, only one physical symptom is required for diagnosis.
Prevalence & Impact
GAD affects approximately 5% of the UK population over their lifetime. It is a chronic condition that can significantly impair a claimant’s ability to work, maintain relationships, and manage daily tasks. In legal proceedings, the chronic nature of GAD often requires a detailed assessment of the “thin skull” rule—evaluating whether a claimant had a pre-existing vulnerability that was exacerbated by the index event.
GAD in Legal Proceedings
Generalised Anxiety Disorder is a primary consideration in civil litigation and employment law. Courts rely on psychiatric experts to provide clarity on the following critical legal questions:
Accurate diagnosis is essential for damages quantification; GAD often represents a more enduring psychiatric injury than a standard adjustment disorder.
