Assessment

How Anxiety Disorders Are Diagnosed

Diagnosis is a clinical process that considers symptoms, duration, impairment, development, physical health, medicines, substance use and alternative explanations. An online checklist cannot establish a diagnosis.

Assessment

GAD-7 Anxiety Screening Questionnaire

The GAD-7 is a brief validated symptom questionnaire used for screening and monitoring. A score does not by itself diagnose generalized anxiety disorder or determine the right treatment.

Assessment

Anxiety vs Stress

Stress is a response to demands or pressures; an anxiety disorder involves a characteristic pattern of fear, worry or avoidance that persists or causes significant impairment. The two can overlap.

Assessment

Anxiety vs Depression

Anxiety and depression can share sleep, concentration, fatigue and irritability symptoms and often occur together. Assessment looks at mood, loss of interest, fear, worry, risk and functioning.

Assessment

Anxiety vs OCD

OCD involves obsessions, compulsions or both and is classified separately from anxiety disorders. Worry, intrusive thoughts and reassurance seeking can overlap, making accurate assessment important.

Assessment

Anxiety vs PTSD

PTSD requires qualifying trauma exposure and a specific pattern of intrusion, avoidance, negative changes and arousal. Generalized anxiety and panic can occur without trauma and can coexist with PTSD.

Assessment

Anxiety vs ADHD

Anxiety and ADHD can both affect concentration, organization, restlessness and sleep. Developmental history, triggers, symptoms across settings and the timing of impairment help distinguish them.

Assessment

Anxiety vs Bipolar Disorder

Agitation, poor sleep and racing thoughts can occur in anxiety and bipolar mood episodes. Bipolar assessment also considers distinct periods of elevated or irritable mood, energy and activity.

Assessment

Can Thyroid Problems Cause Anxiety?

Thyroid disorders can produce anxiety-like symptoms such as palpitations, tremor, heat intolerance, fatigue or mood change. Testing decisions should be based on clinical assessment rather than symptoms alone.

Assessment

Medication- and Substance-Induced Anxiety

Caffeine, stimulants, cannabis, alcohol withdrawal, some medicines and other substances can cause or worsen anxiety. Sudden symptoms require review of timing, dose, interactions and withdrawal risk.

Assessment

When Anxiety Symptoms Are a Medical Emergency

Call emergency services for severe chest pain, major breathing difficulty, fainting, stroke signs, severe allergic reaction, overdose, dangerous withdrawal, or immediate risk of self-harm or harm to others.
