Overview
Anxiety disorders are among the most common mental health conditions. Anxiety itself is a normal response to stress or danger, but in anxiety disorders the fear or worry is excessive, lasts a long time, and interferes with everyday life. The anxiety is often out of proportion to the actual situation and is hard to control.
There are several types of anxiety disorder, including generalized anxiety disorder, panic disorder, social anxiety disorder, specific phobias, and agoraphobia. They can affect thoughts, feelings, behavior, and the body, and they frequently occur alongside one another or with depression. Anxiety disorders are very treatable, and most people improve significantly with talking therapy, medication, or a combination, especially when they seek help early.
Symptoms
Anxiety disorders share emotional, behavioral, and physical symptoms, though the exact pattern varies by type.
- Excessive worry, fear, or a sense of dread
- Feeling restless, on edge, or unable to relax
- Avoiding feared situations, places, or activities
- Difficulty concentrating and irritability
- Trouble sleeping
- Physical symptoms: a racing heart, shortness of breath, sweating, trembling, dizziness, muscle tension, or stomach upset
- Panic attacks: sudden surges of intense fear with strong physical symptoms in some disorders
The focus of the anxiety differs: generalized worry in GAD, social situations in social anxiety, specific triggers in phobias, and sudden attacks in panic disorder.
Causes
Anxiety disorders arise from a combination of factors rather than one cause.
- Genetics: Anxiety disorders tend to run in families.
- Brain function: Differences in the brain systems and chemicals that regulate fear and worry.
- Temperament: Being naturally more sensitive, cautious, or prone to negative emotions.
- Life experiences: Stressful or traumatic events, especially in childhood, and ongoing stress.
- Physical factors: Some medical conditions, caffeine, and certain medications or substances can trigger or worsen anxiety.
Risk Factors
- A family history of anxiety or other mental health conditions
- A history of trauma or chronic stress
- A shy, sensitive, or anxious temperament
- Other mental health conditions, such as depression
- Chronic physical illness
- Excess caffeine, alcohol, or substance use
Diagnosis
Anxiety disorders are diagnosed through clinical assessment, with the specific type identified by the pattern of symptoms.
- Clinical interview: Exploring the nature, triggers, duration, and impact of the anxiety.
- Diagnostic criteria: Each type has defined criteria, generally involving excessive anxiety causing distress or impairment over a period of time.
- Screening questionnaires: To help identify and measure anxiety.
- Medical evaluation: To rule out physical causes such as thyroid problems and review caffeine, alcohol, and medications.
Treatment
Anxiety disorders respond well to treatment, which usually includes therapy, medication, or both.
- Cognitive behavioral therapy (CBT): The most effective talking therapy; it helps change anxious thoughts and gradually face feared situations.
- Exposure therapy: Especially helpful for phobias, panic, and social anxiety.
- Medication: Antidepressants such as SSRIs and SNRIs are commonly used; other medicines are used in specific situations. Long-term sedative use is generally avoided due to dependence risk.
- Lifestyle measures: Regular exercise, good sleep, stress management, and limiting caffeine and alcohol.
Self-Care and Coping
- Practice relaxation techniques such as slow breathing and mindfulness
- Exercise regularly to reduce anxiety and improve mood
- Keep a consistent sleep schedule
- Limit caffeine and alcohol, which can heighten anxiety
- Face feared situations gradually rather than avoiding them
- Stay connected with supportive people and seek help early

See a doctor or mental health professional if anxiety is persistent, feels out of control, or interferes with your work, relationships, sleep, or daily activities. Anxiety disorders are very treatable, and early help leads to better outcomes. Seek urgent help, or contact emergency services or a crisis helpline, if you ever have thoughts of harming yourself or feel unable to cope, as effective support is available and these feelings can improve with care.
