What is generalized anxiety disorder?
Generalized anxiety disorder (GAD) is excessive, uncontrollable worry about everyday matters lasting ≥6 months, with at least 3 associated symptoms (restlessness, fatigue, concentration difficulty, irritability, muscle tension, sleep disturbance). Lifetime prevalence ~5-9% in US adults. Frequently comorbid with depression.
What are the symptoms of generalized anxiety disorder?
- Excessive worry about multiple domains, hard to control, most days for ≥6 months (GAD)
- Sudden episodes of intense fear with physical symptoms (panic disorder)
- Restlessness, muscle tension, fatigue not explained by sleep
- Difficulty concentrating or 'mind going blank'
- Irritability and sleep disturbance (often early symptom)
- Avoidance behaviors that constrain daily life
Who is at risk for generalized anxiety disorder?
- Family history of anxiety or mood disorders
- Female sex (lifetime prevalence ~2x men)
- Adverse childhood experiences or chronic stress
- Co-occurring depression, ADHD, or substance use
- Some medical conditions: thyroid disease, asthma, IBD, chronic pain
- Caffeine and stimulant exposure (worsens existing anxiety, can trigger panic)
How is generalized anxiety disorder diagnosed?
DSM-5-TR criteria + GAD-7 screening tool (score ≥10 suggests moderate-severe GAD). Workup considers thyroid disease, caffeine intake, and substance use. Acute panic with chest pain warrants cardiac evaluation.
How is generalized anxiety disorder treated?
First-line: SSRIs (escitalopram, sertraline) or SNRIs (venlafaxine, duloxetine) plus CBT. Buspirone is an alternative for patients avoiding antidepressants. Benzodiazepines (alprazolam, clonazepam) used short-term only due to dependence risk. Lifestyle: regular exercise, sleep hygiene, caffeine reduction. Telehealth is well-suited to GAD given chronic management needs.

What's the difference between SSRIs and benzodiazepines for anxiety?
SSRIs (sertraline, escitalopram) treat chronic anxiety over weeks; they're first-line for long-term management because they don't cause dependence. Benzodiazepines (alprazolam, lorazepam) act within hours but carry dependence risk after even brief regular use; clinical guidance now restricts them to short-term bridging or specific panic-attack scenarios.
Can anxiety disorders be cured?
Many patients achieve sustained remission with adequate treatment (medication + CBT for 6-12 months, then continuation/maintenance based on severity). The chronic vs episodic course varies; recurrence risk remains, and ongoing self-management skills built during therapy reduce recurrence.
Does CBT work as well as medication for anxiety?
For mild-to-moderate generalized anxiety and panic disorder, head-to-head trials show CBT and SSRI/SNRI similarly effective at 12 weeks. CBT outperforms medication on long-term outcomes after treatment ends, because skills persist. Combined treatment outperforms either alone for moderate-to-severe cases.
Will caffeine make my anxiety worse?
Yes, often. Caffeine activates the same sympathetic nervous system pathways that drive anxiety symptoms — particularly in panic disorder, where caffeine can directly trigger attacks. Reducing intake to <200 mg/day (one strong coffee) or eliminating it entirely is a low-cost first intervention.
