Anxiety Disorders

Overview

Anxiety disorders are among the most common mental health conditions, affecting nearly 30% of adults at some point in their lives. While anxiety is a normal response to stress and can be beneficial in some situations, anxiety disorders involve excessive fear or anxiety that interferes with daily activities. These disorders are highly treatable, yet only about 37% of those suffering receive treatment. Unlike the relatively mild, brief anxiety caused by stressful events, anxiety disorders last at least 6 months and can worsen without treatment.

Anxiety disorders differ from normal feelings of nervousness or anxiousness and involve excessive fear or anxiety that is out of proportion to the situation. They can cause people to avoid situations that trigger or worsen their symptoms, affecting job performance, schoolwork, and relationships. The good news is that anxiety disorders are treatable, and several effective treatments are available. Treatment helps most people lead normal, productive lives.

These conditions often begin in childhood or adolescence and may continue into adulthood if left untreated. Women are twice as likely as men to be affected by most anxiety disorders. The disorders can range from specific phobias, which are fairly circumscribed, to generalized anxiety disorder, which involves persistent worry about various aspects of daily life. Understanding the specific type of anxiety disorder is crucial for proper treatment, as different types may respond better to different therapeutic approaches.

Types of Anxiety Disorders

There are several types of anxiety disorders, each with unique features:

Generalized Anxiety Disorder (GAD)

• Persistent, excessive worry about various aspects of life
• Worry is difficult to control and disproportionate to actual risk
• Occurs most days for at least 6 months
• Affects about 3% of the population annually
• Often develops gradually and can occur at any age

Panic Disorder

• Recurrent unexpected panic attacks
• Intense fear that peaks within minutes
• Physical symptoms mimic heart attack
• Fear of future attacks leads to behavioral changes
• May develop agoraphobia (fear of places where escape might be difficult)

Social Anxiety Disorder (Social Phobia)

• Intense fear of social or performance situations
• Fear of being judged, embarrassed, or humiliated
• May be limited to specific situations or generalized
• Often begins in teenage years
• Can severely impact work and social life

Causes

Anxiety disorders result from a complex interaction of biological, psychological, and environmental factors. Understanding these causes helps in developing effective treatment strategies.

Biological Factors

Diagnosis

Diagnosing anxiety disorders involves comprehensive assessment by a mental health professional. There are no laboratory tests to diagnose anxiety disorders, so diagnosis relies on clinical evaluation.

Initial Assessment

Clinical Interview

• Impact on daily functioning
• Family history of mental health conditions
• Medical history and current medications
• Substance use history
