Types of Anxiety Disorders - Symptoms, Causes, Treatment & Coping Strategies

Anxiety is a normal human response to stress, helping us stay alert and focused. However, when anxiety becomes persistent, overwhelming, or disproportionate, it transforms into a disorder that interferes with daily functioning. Anxiety disorders are among the most common mental health conditions, affecting more than 300 million people worldwide, according to the World Health Organization.

Anxiety disorders manifest in different forms—ranging from generalized anxiety to panic attacks, phobias, and obsessive-compulsive patterns. Recognizing these types helps in seeking proper care and reducing stigma.
