When Worry Becomes Generalized Anxiety Disorder
GAD isn't just "worrying a lot." It's a chronic, uncontrollable worry that impairs daily functioning. Here's the diagnostic threshold.

Everyone worries. Worry is a normal, adaptive cognitive process — it helps us anticipate problems and plan solutions. But in Generalised Anxiety Disorder (GAD), worry becomes chronic, uncontrollable, and pervasive. It shifts from a useful tool to a relentless mental noise that impairs daily functioning.
The Diagnostic Criteria
GAD is diagnosed when excessive anxiety and worry about multiple domains (work, health, family, finances) occurs more days than not for at least 6 months, and the person finds it difficult to control the worry. The worry must cause significant distress or impairment and be accompanied by at least three of the following symptoms.
GAD symptoms (3+ required for diagnosis):
- Restlessness or feeling keyed up or on edge
- Being easily fatigued
- Difficulty concentrating or mind going blank
- Irritability
- Muscle tension
- Sleep disturbance (difficulty falling or staying asleep)
The Worry About Worry
A key feature of GAD is metacognitive beliefs about worry itself — beliefs that worry is either useful ("If I worry, I'll be prepared") or dangerous ("My worrying will make me ill"). These beliefs maintain the worry cycle. CBT for GAD specifically targets these metacognitive beliefs alongside the content of the worries.
Effective treatments for GAD include CBT (particularly metacognitive therapy), acceptance-based approaches, and medication (SSRIs, SNRIs, buspirone). Response rates with CBT are approximately 50–60%.
