Anxiety is a normal human emotion that helps people respond to danger and prepare for challenges. An anxiety disorder is different. It involves fear or worry that is persistent, out of proportion to the situation, hard to control, and interferes with daily life. Anxiety disorders are the most common mental health conditions, affecting many people at some point in their lives. They often begin in childhood, adolescence, or early adulthood. There are several types, each with its own focus, but they share common features, including physical symptoms, avoidance, and a tendency to overestimate threat. Anxiety disorders are highly treatable.

The Main Types of Anxiety Disorder

• Generalized anxiety disorder. Persistent, excessive worry about many areas of life, such as health, work, and family, that is hard to control.
• Panic disorder. Recurrent unexpected panic attacks and ongoing fear of having more, explained on the page about panic attacks and panic disorder.
• Social anxiety disorder. Intense fear of being judged or embarrassed in social or performance situations, described on the page about social anxiety disorder.
• Specific phobias. Intense fear of particular objects or situations, such as heights, flying, or needles, covered on the page about specific phobias.
• Agoraphobia. Fear of situations where escape might be difficult or help unavailable, such as crowds or public transit, explored on the page about agoraphobia.
• Separation anxiety disorder. Excessive fear about being apart from attachment figures, in children and adults.
• Selective mutism. Consistent inability to speak in certain social situations, most common in children.

Obsessive-compulsive disorder and post-traumatic stress disorder were once grouped with anxiety disorders. They are now classified separately, though anxiety is central to both.

Why They Happen

Anxiety disorders develop from a combination of genetics, brain biology, temperament, and life experiences. Some people are born with a more sensitive threat response. Stressful or traumatic events, chronic stress, and growing up in an anxious or unpredictable environment increase risk. Certain thinking patterns, such as overestimating danger, underestimating coping ability, and difficulty tolerating uncertainty, keep anxiety going. Avoidance plays a major role: avoiding feared situations brings short-term relief but prevents new learning, so fear persists or grows.

Medical conditions, such as thyroid problems, and substances, such as caffeine, alcohol, and some medications, can cause or worsen anxiety symptoms. Anxiety disorders often co-occur with each other and with depression.

Anxiety disorders can look different at different ages. Children may show anxiety through clinginess, stomach aches, or refusing school. Teens may withdraw or become irritable. Older adults may focus more on health or safety worries. Recognizing these variations helps people get support at any stage of life.

Many people live with anxiety for years before seeking help, sometimes because they believe it is simply part of their personality. Recognizing that anxiety disorders are common and treatable can make it easier to reach out.

What They Are Not

• Not ordinary nervousness. Anxiety disorders are persistent and interfere with life.
• Not a sign of weakness. They are common health conditions.
• Not something to simply push through. Avoidance and suppression often make anxiety worse.
• Not permanent. Most people improve significantly with treatment.

How They Are Assessed and Treated

A clinician will ask about worries and fears, physical symptoms, avoidance, duration, and how daily life is affected, and a physician may check for medical causes. Cognitive behavioural therapy is the most studied treatment for all anxiety disorders. It helps people identify anxious thinking, gradually face feared situations through exposure, and build coping skills. Acceptance and commitment therapy and mindfulness-based approaches are also helpful. Medications may be recommended, particularly for moderate to severe anxiety. Regular exercise, sleep, limiting caffeine and alcohol, and social support all support recovery.
