Difference Between Panic Attack and Anxiety Attack
Panic attacks are a distinct clinical entity with specific diagnostic criteria (DSM-IV), while "anxiety attacks" is not a formal medical diagnosis but rather colloquial terminology for heightened anxiety symptoms. 1
Clinical Definition of Panic Attack
A panic attack is formally defined as a discrete period of intense fear or discomfort in which four or more of the following symptoms develop abruptly and reach a peak within 10 minutes: 1
- Palpitations, pounding heart, or accelerated heart rate 1
- Sweating 1
- Trembling or shaking 1
- Sensations of shortness of breath or smothering 1
- Feeling of choking 1
- Chest pain or discomfort 1
- Nausea or abdominal distress 1
- Feeling dizzy, unsteady, lightheaded, or faint 1
- Derealization (feelings of unreality) or depersonalization (being detached from oneself) 1
- Fear of losing control 1
- Fear of dying 1
- Paresthesias (numbness or tingling sensations) 1
- Chills or hot flushes 1
What People Call "Anxiety Attacks"
When patients describe "anxiety attacks," they typically refer to symptoms of generalized anxiety that may include: 1
- Unrealistic or excessive worry about multiple life circumstances 1
- Motor tension (trembling, muscle tension, restlessness, easy fatigability) 1
- Autonomic hyperactivity (shortness of breath, palpitations, sweating, dry mouth, dizziness, nausea) 1
- Vigilance and scanning (feeling keyed up or on edge, exaggerated startle response, difficulty concentrating, trouble sleeping, irritability) 1
The key distinction is that panic attacks have a sudden onset, reach peak intensity within 10 minutes, and require at least 4 specific symptoms, whereas generalized anxiety symptoms build more gradually and persist over longer periods. 1
Treatment Approach
For Panic Disorder (Recurrent Panic Attacks)
Combination treatment with cognitive-behavioral therapy (CBT) plus an SSRI provides superior outcomes compared to either treatment alone. 2, 3
First-line pharmacotherapy: 4, 3
- Sertraline: Start 25-50 mg daily, titrate by 25-50 mg every 1-2 weeks to target dose of 50-200 mg/day 4
- Escitalopram: Start 5-10 mg daily, titrate by 5-10 mg increments to target dose of 10-20 mg/day 4
- Fluoxetine: Start 5-10 mg daily, increase by 5-10 mg every 1-2 weeks to target dose of 20-40 mg/day 4
Expected timeline: Statistically significant improvement begins at week 2, clinically significant improvement by week 6, maximal benefit by week 12 or later 4
CBT components for panic disorder: 2, 3
- Education about the nature of panic disorder 3
- Cognitive restructuring to challenge catastrophic misinterpretations of bodily sensations 3
- Interoceptive exposure (deliberately inducing feared physical sensations in a controlled manner) 2
- Breathing retraining and relaxation techniques 3
- Gradual exposure to situations that trigger panic 3
For Generalized Anxiety Disorder
CBT is recommended as first-line treatment for mild to moderate presentations, with SSRIs/SNRIs as alternatives for more severe presentations or when quality CBT is unavailable. 5
First-line medications: 4
- Escitalopram or sertraline (SSRIs) 4
- Duloxetine 60-120 mg/day (SNRI) - particularly beneficial for comorbid pain conditions 4
- Venlafaxine extended-release 75-225 mg/day (SNRI) - requires blood pressure monitoring 4
CBT for GAD includes: 4
- Education on anxiety 4
- Cognitive restructuring to challenge distortions 4
- Relaxation techniques 4
- Gradual exposure when appropriate 4
- Structured duration of 12-20 sessions 4
Critical Monitoring and Safety Considerations
All SSRIs carry a boxed warning for suicidal thinking and behavior, with pooled absolute rates of 1% versus 0.2% for placebo. 4 Close monitoring is essential, especially in the first months and following dose adjustments. 4
Common SSRI/SNRI side effects that emerge within the first few weeks include nausea, sexual dysfunction, headache, insomnia, dry mouth, diarrhea, and dizziness. 4 Most resolve with continued treatment. 4
What to Avoid
Benzodiazepines (such as alprazolam) should be reserved for short-term use only due to risks of dependence, tolerance, and withdrawal. 4, 1 While alprazolam is FDA-approved for panic disorder and can provide rapid symptom relief, 1 the risk of dependence increases with dose and duration of treatment. 1 Abrupt discontinuation must be avoided - dosage should be decreased by no more than 0.5 mg every 3 days when discontinuing. 1
Tricyclic antidepressants should be avoided due to unfavorable risk-benefit profile, particularly cardiac toxicity. 4
Treatment Duration
Medications should be continued for at least 12-24 months after remission, 6, 7 and in some cases indefinitely for panic disorder. 7 Discontinue gradually to avoid withdrawal symptoms, particularly with shorter half-life SSRIs. 4
