Introduction
Generalized Anxiety Disorder (GAD) is a chronic anxiety condition characterized by persistent, excessive, and difficult-to-control worry about a wide range of everyday matters — such as health, finances, work, family, and future events — that is disproportionate to the actual likelihood or impact of the anticipated problem. GAD is one of the most common anxiety disorders and significantly affects quality of life when left untreated.
Causes
GAD develops from a combination of genetic, neurobiological, and environmental factors. A family history of anxiety disorders increases risk, as does a history of trauma, chronic stress, or significant life adversity. Neurobiological research points to dysregulation in brain areas governing fear and stress responses, including the amygdala and prefrontal cortex, and imbalances in neurotransmitters such as serotonin, GABA, and norepinephrine.
Symptoms
Core symptoms include excessive worry occurring more days than not for at least six months, difficulty controlling the worry, and at least three physical or psychological symptoms such as restlessness, fatigue, difficulty concentrating, irritability, muscle tension, and sleep disturbances. The worry and its associated symptoms cause significant distress or impairment in social, occupational, or other important areas of functioning.
Diagnosis
A clinician diagnoses GAD through clinical interview and review of symptom duration, severity, and impact on functioning. DSM-5 criteria require excessive anxiety and worry about multiple topics for at least six months with associated symptoms not attributable to substances or another medical condition. Standardized tools such as the GAD-7 questionnaire are often used to assess symptom severity and track treatment response.
Treatment
Cognitive behavioral therapy (CBT) is the most evidence-based psychotherapy for GAD, helping patients challenge worry-producing thought patterns and develop practical coping strategies. Relaxation techniques, mindfulness, and acceptance-based approaches are also effective. First-line medications include SSRIs and SNRIs, with buspirone as an alternative. Benzodiazepines may be used short-term with caution due to dependence risk.
