Summary
Panic disorder affects 2.3% of people lifelong, with higher prevalence in women and those living alone. While often comorbid with other conditions, two-thirds of patients experience good prognosis if occasional panic attacks are acceptable.
Area of Science:
- Epidemiology of mental health disorders.
- Clinical psychiatry and psychology.
- Public health and preventative medicine.
Context:
- Panic disorder affects 2.3% of the population lifetime and 0.5-1% annually.
- Prevalence of panic attacks ranges from 4-12% globally.
- Consultation rates vary by medical specialty, notably cardiology and emergency services.
Purpose:
- To summarize the epidemiological characteristics of panic disorder.
- To identify demographic and socioeconomic factors influencing prevalence.
- To review predisposing factors, comorbidities, and prognostic indicators.
Summary:
- Panic disorder is more prevalent in women, younger/middle-aged individuals, and those living alone.
- Socio-educational level is a key socioeconomic determinant, more so than income or profession.
- Genetic and psychoaffective factors (childhood trauma, separation anxiety) contribute to its development.
- Comorbidities with anxiety disorders, depression, and substance abuse are common and indicate a poorer prognosis.
- Complete remission rates are 10-20% at 3-5 years, but prognosis is favorable for two-thirds if occasional attacks are tolerated.
Impact:
- Informs public health strategies for mental health awareness and early intervention.
- Highlights the importance of considering panic disorder in primary care and emergency settings.
- Guides clinical practice in assessing risk factors and managing comorbid conditions for improved patient outcomes.
