Generalised Anxiety Disorder (GAD)

What is Generalised Anxiety Disorder?

Generalised Anxiety Disorder (GAD) is a mental health condition characterised by persistent, excessive worry and anxiety about multiple areas of life that are difficult to control and interfere with daily functioning. Unlike normal anxiety that comes and goes in response to specific stressors, GAD involves chronic, pervasive worry that lasts for months or years and is often disproportionate to the actual circumstances.

What does it feel like to have Generalised Anxiety Disorder?

People with GAD often describe feeling like they're constantly "on edge" or waiting for something bad to happen. The worry feels uncontrollable and can shift from one concern to another throughout the day. Common experiences include:

Mental symptoms:

• Persistent worrying about everyday situations like work, health, finances, or family
• Difficulty controlling anxious thoughts
• Overthinking plans and imagining worst-case scenarios
• Trouble concentrating or feeling like your mind "goes blank"
• Indecisiveness and fear of making the wrong choice
• Perceiving situations as threatening when they're not

Physical symptoms:

• Muscle tension and aches
• Fatigue and feeling easily tired
• Restlessness or feeling "keyed up"
• Trouble sleeping or staying asleep
• Trembling or feeling twitchy
• Sweating, nausea, or digestive problems
• Headaches and irritability

How common is Generalised Anxiety Disorder?

GAD is one of the most common anxiety disorders globally:

United States:

• Affects approximately 3.1% of U.S. adults annually
• Lifetime prevalence of 5.7% in the U.S. population
• Women are twice as likely as men to experience GAD

Global prevalence:

• Affects millions of people worldwide
• Part of anxiety conditions that affect 1 in 4 people in Australia (Beyond Blue)
• More common in women than men across all cultures

Age of onset:

• Usually develops gradually and starts in early adulthood
• Can occur at any age, including childhood and later life
• Often co-occurs with other mental health conditions

What causes Generalised Anxiety Disorder?

The exact cause of GAD is unknown, but research suggests it results from a complex interaction of multiple factors:

Biological factors:

• Genetics: GAD may run in families
• Brain chemistry differences, particularly involving neurotransmitters
• Differences in brain function and structure

Environmental factors:

• Traumatic or negative experiences during childhood
• Significant life changes or stressful events
• Chronic medical illnesses
• History of other mental health disorders

Personality factors:

• Temperament that is timid, negative, or avoids perceived dangers
• Perfectionist tendencies
• Difficulty handling uncertainty

GAD is "more common in women than men" and can be triggered by various life circumstances.

How is Generalised Anxiety Disorder diagnosed?

To be diagnosed with GAD, specific criteria must be met:

Diagnostic criteria (based on DSM-5):

• Excessive anxiety and worry occurring more days than not for at least 6 months
• Difficulty controlling the worry
• The anxiety is associated with at least three of the following symptoms:
  • Restlessness or feeling "on edge"
  • Being easily fatigued
  • Difficulty concentrating
  • Irritability
  • Muscle tension
  • Sleep disturbances

Assessment process:

• Comprehensive evaluation by a healthcare provider
• Discussion of symptoms, their duration, and impact on daily life
• Physical examination to rule out medical causes
• Assessment for co-occurring mental health conditions

Finding it difficult to control worry on most days for at least 6 months is a key diagnostic criterion.

What are the treatment options for Generalised Anxiety Disorder?

GAD is highly treatable with various evidence-based approaches:

Psychotherapy

Cognitive Behavioural Therapy (CBT):

• Considered the "gold standard" for GAD treatment (NIMH)
• Helps identify and change negative thought patterns
• Teaches coping skills and relaxation techniques
• Strong research support for effectiveness

Acceptance and Commitment Therapy (ACT):

• Focuses on accepting anxious thoughts rather than fighting them
• Emphasises engagement in meaningful activities
• Uses mindfulness and goal-setting strategies
• Growing evidence base for GAD treatment

Medication

Antidepressants:

• SSRIs (Selective Serotonin Reuptake Inhibitors)
• SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors)
• May take several weeks to show full effects
• Generally well-tolerated with manageable side effects

Anti-anxiety medications:

• Benzodiazepines for short-term, severe symptoms
• Buspirone as a non-addictive alternative
• Careful monitoring required due to dependency risks

Combination treatment:

Research shows that combining psychotherapy and medication often provides the best outcomes for GAD.

Self-help strategies for managing GAD

Lifestyle modifications:

• Regular exercise (walking, swimming, yoga)
• Adequate sleep (7-9 hours per night)
• Healthy diet with regular meals
• Limiting caffeine and alcohol
• Avoiding recreational drugs

Stress management:

• Deep breathing exercises
• Progressive muscle relaxation
• Mindfulness and meditation
• Time management and prioritisation
• Journaling to track triggers and patterns

Social support:

• Talking to trusted friends or family members
• Joining support groups
• Maintaining social connections
• Seeking professional help when needed

When to seek professional help

Seek professional help if:

• Worry is interfering with work, relationships, or daily activities
• You feel depressed or have thoughts of self-harm
• You're using alcohol or drugs to cope with anxiety
• Physical symptoms are causing distress
• Self-help strategies aren't providing relief

Try to seek professional help before your anxiety becomes severe; it may be easier to treat early on.

Living with Generalised Anxiety Disorder

With proper treatment and support, people with GAD can:

• Learn to manage their symptoms effectively
• Improve their quality of life significantly
• Develop healthy coping strategies
• Maintain fulfilling relationships and careers
• Experience periods of reduced anxiety

Recovery is possible, and many people with GAD go on to live full, productive lives. The key is finding the right combination of treatments and developing effective coping strategies.

Co-occurring conditions

GAD often occurs alongside other mental health conditions:

• Depression (very common)
• Other anxiety disorders (panic disorder, social anxiety)
• Post-traumatic stress disorder (PTSD)
• Obsessive-compulsive disorder (OCD)
• Substance use disorders

Having multiple conditions can make treatment more complex, but doesn't prevent recovery with comprehensive care.

Support for families and caregivers

Family members and friends can provide crucial support by:

• Learning about GAD and its symptoms
• Encouraging treatment and recovery
• Being patient and understanding
• Avoiding criticism or minimising concerns
• Taking care of their own mental health
