Generalised anxiety disorder matters because the worry spreads across many areas of life at once, rather than centring on one specific trigger or discrete attacks. It is diagnosed as excessive, difficult-to-control worry about a number of everyday events or activities, present for most days over at least six months. For example, imagine a man who worries intensely about his health, his finances, his children's safety and being late for work, all in the same afternoon, with no single dominant concern. In practice, that free-floating worry across many unrelated domains is what separates this from a fear tied to one specific situation.

Associated symptoms include restlessness or feeling on edge, being easily fatigued, difficulty concentrating, irritability, muscle tension, and sleep disturbance, typically difficulty falling or staying asleep. Unlike panic disorder, generalised anxiety disorder does not centre on discrete, time-limited surges of fear, the anxiety instead stays present as a persistent background hum most days. Take a patient who feels a constant low-grade tension and cannot pinpoint any single trigger, rather than describing sudden peaks of terror. In practice, that steady, pervasive quality, rather than sudden spikes, is what points toward generalised anxiety disorder.

• A man newly diagnosed with mild generalised anxiety disorder has had no treatment. What does NICE recommend at this first step?
• For how long must excessive worry be present before generalised anxiety disorder can be diagnosed under ICD-11?
• Which condition most commonly occurs alongside generalised anxiety disorder in adults?

• Panic disorder, discrete, time-limited surges of intense fear, unlike generalised anxiety disorder's steady, persistent background worry.
• Specific phobia, fear tied to one clearly defined trigger, rather than generalised anxiety disorder's worry spread across many life domains.
• Generalised anxiety disorder, requires symptoms most days for at least six months, unlike adjustment disorder, which follows a specific recent stressor.
• Depression, low mood and anhedoniaThe loss of the ability to feel pleasure from things that used to be enjoyable.Read more → (loss of pleasure) as the core feature, whereas generalised anxiety disorder centres on excessive, hard-to-control worry.

• Benzodiazepines are not recommended other than as a short-term crisis measure.
• Admission is not indicated for uncomplicated generalised anxiety disorder.
• Drug treatment belongs at a later step, after low-intensity psychological interventions have been tried.
• Specialist referral is the final step, reserved for severe or treatment-refractory presentations.
• A few days of worry falls well short of the required persistence.

• Extract the defining phenomenology, duration, severity and functional-impact clues.
• Match the pattern to the most specific diagnostic or assessment construct.
• Actively test the closest look-alike against the missing or contradictory clue.
• Choose the precise term rather than a broader category that is merely compatible.
