What Is an Anxiety Disorder?

Feeling anxious before a job interview or a medical procedure is normal. An anxiety disorder, however, involves persistent, excessive worry that interferes with daily functioning. According to the World Health Organization, anxiety disorders affect approximately 264 million people globally — making them the most prevalent mental health condition.

Types of Anxiety Disorders

  • Generalised Anxiety Disorder (GAD): Persistent worry about a wide range of everyday situations, lasting six months or more.
  • Panic Disorder: Recurrent, unexpected panic attacks accompanied by intense physical symptoms including racing heart, chest tightness, and shortness of breath.
  • Social Anxiety Disorder: Intense fear of social situations due to concerns about embarrassment or judgment.
  • Specific Phobias: Irrational fear of a specific object or situation that provokes immediate anxiety.
  • Post-Traumatic Stress Disorder (PTSD): Anxiety following exposure to a traumatic event.

Pharmaceutical Treatments for Anxiety

The most commonly prescribed medications for anxiety disorders include SSRIs (selective serotonin reuptake inhibitors) such as sertraline and escitalopram, which are considered first-line treatments for long-term management. SNRIs, buspirone, and beta-blockers are also used depending on the specific anxiety presentation.

Benzodiazepines — including alprazolam (Xanax), diazepam (Valium), and clonazepam (Klonopin) — provide rapid relief and are typically prescribed for short-term or situational use. Due to their potential for dependence, they are generally reserved for acute episodes rather than long-term management.

Effective anxiety treatment almost always combines pharmaceutical support with therapy, particularly CBT, which addresses the thought patterns and avoidance behaviours that maintain anxiety over time.
