Anxiety Disorder Criteria – From Intuition to Precision
Everyone feels anxious sometimes. That knot in your stomach before an exam, the racing heart before a speech, the restless night before a big decision — these are normal, even useful. Anxiety is your brain's alarm system, alerting you to potential danger and preparing your body to respond. It sharpens focus, boosts energy, and helps you perform.
But what happens when the alarm keeps ringing when there is no fire? When the feeling of dread shows up without a clear trigger, or lingers long after the threat is gone, or is so intense that it stops you from living your life? That is when normal anxiety crosses into an anxiety disorder.
The key difference is not the presence of anxiety — it is whether the anxiety is excessive, uncontrollable, and impairing.
The Intuitive Core: Three Questions
To decide if anxiety has become a disorder, ask three simple questions:
-
Is the anxiety out of proportion?
A mild worry about a minor exam is normal. Crippling terror about a routine class presentation is not.
-
Can the person control it?
Normal anxiety fades when the situation ends. In a disorder, the person feels helpless — the anxiety comes and stays despite knowing it is irrational.
-
Does it interfere with life?
Avoiding social events, skipping classes, losing sleep, or being unable to work because of anxiety signals a problem.
If the answer to all three is "yes" for a sustained period, you are looking at a disorder.
The Precise Statement: DSM-5 Criteria
The standard diagnostic framework (DSM-5) defines Generalized Anxiety Disorder as a representative example. The criteria are:
DSM-5 Criteria for Generalized Anxiety Disorder (300.02)
A. Excessive anxiety and worry, occurring more days than not for at least 6 months,about a number of events or activities.B. The person finds it difficult to control the worry.C. The anxiety and worry are associated with three (or more) of the following six symptoms:1. Restlessness or feeling keyed up or on edge2. Being easily fatigued3. Difficulty concentrating or mind going blank4. Irritability5. Muscle tension6. Sleep disturbance (difficulty falling/staying asleep, or restless unsatisfying sleep)D. The anxiety, worry, or physical symptoms cause clinically significant distressor impairment in social, occupational, or other important areas of functioning.E. The disturbance is not due to the direct physiological effects of a substance(e.g., drug abuse, medication) or another medical condition.F. The disturbance is not better explained by another mental disorder.
Breaking Down Each Criterion
Criterion A – Duration and Pervasiveness
The worry must be present more days than not for at least 6 months. This rules out temporary stress reactions. The worry is also about multiple domains — not just one specific thing (that would be a phobia).
Criterion B – Lack of Control
This is the hallmark. The person knows the worry is excessive but cannot stop it. It is not a choice; it is a symptom.
Criterion C – Somatic and Cognitive Symptoms
Anxiety is not just in the mind — it lives in the body. The six symptoms listed are the most common physical and mental manifestations. A diagnosis requires three or more of these.
Criterion D – Functional Impairment
This is the most important practical test. Even if all other criteria are met, if the person can still function normally, it is not a disorder. The anxiety must cause clinically significant distress or impairment in real life — at work, in relationships, in daily tasks.
Criteria E and F – Exclusion
These ensure the anxiety is not caused by something else — a thyroid problem, caffeine intoxication, withdrawal from alcohol, or another mental disorder like depression or PTSD.
