Anxiety is a regular human emotion that every person experiences at times. Anxiety disorders, however, are different. Anxiety disorders are a category of mental disorders characterised by feelings of anxiety and fear, where anxiety is a worry about future events and fear is a reaction to current events. These feelings may cause physical symptoms, such as a racing heart and shakiness and can cause such distress that it hampers a person’s ability to lead a normal life. Millions of children and adult suffer from these disorders.

Types of Anxiety Disorders

There are several recognised types of anxiety disorders, which include:

  • Panic disorder: People with this condition have feelings of terror that strike suddenly and repeatedly with no warning. Other symptoms of a panic attack include sweating, chest pain, palpitations and a feeling of choking.
  • Social anxiety disorder: Also called social phobia, social anxiety disorder involves overwhelming worry and self-consciousness about everyday social situations. The worry often centers on a fear of being judged by others or behaving in a way that might cause embarrassment or lead to ridicule.
  • Phobias: A specific phobia is an intense fear of a specific object or situation, such as snakes, heights, or flying. The level of fear is usually inappropriate to the situation and may cause the person to avoid common, everyday situations.
  • Generalized anxiety disorder: This disorder involves excessive, unrealistic worry and tension, even if there is little or nothing to provoke the anxiety.
