Anxiety Disorders

Understanding the complexities, symptoms, and treatments of anxiety-related conditions

Definition

Anxiety disorders are a group of mental health conditions characterized by excessive and persistent fear, worry, and related behavioral disturbances. Unlike the normal anxiety people experience in stressful situations, anxiety disorders involve disproportionate emotional responses that significantly interfere with daily activities, relationships, and overall quality of life.

These disorders are among the most common mental health conditions worldwide, affecting millions of people across all age groups. They can manifest in various forms, each with unique characteristics, but all share the core feature of excessive fear and anxiety.
