Anxiety disorders are among the most common mental health conditions worldwide, affecting approximately 284 million people globally, according to the World Health Organization. In the United Kingdom, mixed anxiety and depression is the most common mental health problem, with around 8% of people experiencing this condition at any one time, as reported by the Mental Health Foundation. Understanding anxiety disorders, their symptoms, causes, and treatment options is crucial for both sufferers and their support networks.
Understanding Anxiety Disorders
Anxiety is a natural human response to stress and perceived threats, serving an important protective function. However, when anxiety becomes excessive, persistent, and interferes with daily functioning, it may constitute an anxiety disorder. The NHS defines anxiety disorders as conditions where anxiety is the main symptom and significantly impacts a person’s ability to cope with daily life.
Normal Anxiety vs. Anxiety Disorders:
Normal Anxiety:
- Proportional to the situation
- Temporary and situation-specific
- Doesn’t significantly impair functioning
- Manageable with coping strategies
- Decreases once the stressor is removed
Anxiety Disorders:
- Disproportionate to the actual threat
- Persistent and long-lasting
- Significantly impairs daily functioning
- Difficult to control or manage
- May occur without clear triggers
Types of Anxiety Disorders
The American Psychiatric Association recognises several distinct anxiety disorders, each with unique characteristics and symptoms:
Generalised Anxiety Disorder (GAD):
GAD is characterised by excessive, uncontrollable worry about various life areas for at least six months. The Royal College of Psychiatrists identifies GAD as one of the most common anxiety disorders.
Key Features:
- Persistent worry about multiple life domains
- Difficulty controlling worrying thoughts
- Physical symptoms of anxiety
- Significant impairment in functioning
- Often coexists with depression
Common Worry Topics:
- Health and safety of self and loved ones
- Work or academic performance
- Financial security
- Social relationships
- Future events and possibilities
Panic Disorder:
Characterised by recurrent, unexpected panic attacks and persistent concern about future attacks. The Anxiety UK charity provides extensive resources for panic disorder sufferers.
Panic Attack Symptoms:
- Rapid heartbeat or palpitations
- Sweating and trembling
- Shortness of breath
- Chest pain or discomfort
- Nausea or dizziness
- Fear of dying or losing control
- Derealisation or depersonalisation
Panic Disorder Development:
- Initial panic attacks may be triggered by stress
- Fear of future attacks develops
- Avoidance behaviours may emerge
- Can lead to agoraphobia if untreated
Social Anxiety Disorder (Social Phobia):
Intense fear of social situations where scrutiny by others is possible. The Social Anxiety Association estimates this affects 6.8% of adults annually.
Common Feared Situations:
- Public speaking or presentations
- Meeting new people

Agoraphobia:
Fear of situations where escape might be difficult or embarrassing, or help unavailable during a panic attack.
Commonly Avoided Situations:
- Using public transportation
- Being in open spaces
- Being in enclosed places
- Standing in lines or crowds
- Being outside the home alone
Separation Anxiety Disorder:
While commonly associated with children, this can also affect adults, involving excessive fear about separation from attachment figures.

- Relaxation Training: Progressive muscle relaxation, breathing exercises
- Problem-Solving Skills: Developing coping strategies
Effectiveness:
- Strong evidence across all anxiety disorders
- 60-80% response rates in clinical trials
- Long-lasting benefits beyond treatment
- Can be delivered individually or in groups
Acceptance and Commitment Therapy (ACT):
Focuses on psychological flexibility and values-based living:
- Mindfulness and acceptance strategies
- Defusion from anxious thoughts
- Values clarification and commitment
- Present-moment awareness
Mindfulness-Based Interventions:
Growing evidence for mindfulness approaches:
- Mindfulness-Based Stress Reduction (MBSR)
- Mindfulness-Based Cognitive Therapy (MBCT)
- Regular meditation practice
- Body awareness and acceptance
Pharmacological Treatments:
Selective Serotonin Reuptake Inhibitors (SSRIs):
First-line medication treatment for most anxiety disorders:
Common SSRIs:
- Sertraline (Zoloft)
- Paroxetine (Paxil)
- Fluoxetine (Prozac)
- Escitalopram (Lexapro)
Benefits:

- Examples: Lorazepam, diazepam, alprazolam
- Reserved for crisis situations or short-term use
Other Medications:
- Pregabalin: Effective for GAD
- Buspirone: Non-benzodiazepine anxiolytic
- Beta-blockers: Helpful for performance anxiety
- Antihistamines: Mild anxiolytic effects
Combination Treatments:
Research demonstrates that combining psychological therapy with medication often produces superior outcomes for severe anxiety disorders.
