Generalised Anxiety Disorder: Understanding, Treatment, and Management Strategies

Overview

Generalised Anxiety Disorder (GAD) occurs when anxiety becomes persistent, excessive, and significantly interferes with daily functioning, relationships, and overall quality of life. While anxiety is a normal human emotion that helps us respond to threats and challenges, it becomes a disorder when it is “unwarranted or inappropriate fear or response to a vague or ill-defined threat” that persists beyond normal stress responses.

Understanding GAD is crucial because it affects millions of people worldwide and can severely impact personal, professional, and social functioning. Unlike situational anxiety that resolves when the stressor is removed, GAD involves chronic, excessive worry about multiple life areas that is disproportionate to actual threats and difficult to control. Early identification and appropriate treatment can significantly improve outcomes and help individuals regain control over their lives.

Understanding How Anxiety Becomes a Disorder

Normal Anxiety vs. Anxiety Disorder

Adaptive anxiety serves important functions:

Threat detection: Alerts us to potential dangers
Performance enhancement: Motivates preparation and focus
Survival mechanism: Triggers fight-or-flight response when needed
Time-limited: Resolves when threat passes or situation improves

Anxiety becomes pathological when it:

Persists inappropriately: Continues without clear threat or after threat resolves
Causes significant distress: Creates substantial emotional suffering
Impairs functioning: Interferes with work, relationships, or daily activities
Is disproportionate: Response intensity exceeds actual threat level

Neurobiological Basis

Brain systems involved in anxiety:

Amygdala: Fear processing center that can become hyperactive
Prefrontal cortex: Executive control region that may be underactive
Hypothalamic-pituitary-adrenal axis: Stress response system dysregulation
Neurotransmitter imbalances: GABA, serotonin, norepinephrine alterations

Types of Anxiety Disorders

PTSD: Careful exposure to trauma memories and triggers

Medication Management

Benzodiazepines

Mechanism and characteristics:

GABA enhancement: Increases inhibitory neurotransmitter activity
Rapid onset: Quick relief of acute anxiety symptoms
Short-term use: Generally recommended for brief periods due to dependence risk
Side effects: Sedation, memory impairment, potential for tolerance

Clinical considerations:

Acute situations: Useful for immediate anxiety relief
Bridge therapy: While waiting for antidepressants to take effect

Side effects: Nausea, sexual dysfunction, weight changes

Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs):

Dual action: Block reuptake of both serotonin and norepinephrine
Examples: Venlafaxine, duloxetine, desvenlafaxine
Benefits: May be effective when SSRIs are insufficient
Monitoring: Blood pressure monitoring may be needed

Other antidepressants:

Tricyclic antidepressants: Older class with more side effects but effective
Mirtazapine: May help with sleep and appetite issues
Bupropion: May be helpful for anxiety with depression
