Epidemiology of panic disorder: progress and unresolved issues

Area of Science:

• Psychiatry
• Epidemiology
• Mental Health

Background:

• Panic disorder (PD) affects approximately 2% of adults lifetime, with a 6-month prevalence of 1.2%.
• Panic attacks have a lifetime rate of 9%, with higher prevalence in females and those divorced or separated.
• PD onset peaks between ages 25-44, varying by sex.

Purpose of the Study:

• To summarize current epidemiological findings on panic disorder.
• To highlight the prevalence, risk factors, and co-occurring conditions associated with panic disorder.
• To identify gaps in knowledge regarding the etiology, natural history, and management of panic disorder.

Main Methods:

• Review of recent epidemiological studies on panic disorder and panic attacks.
• Analysis of prevalence rates, demographic associations, and co-morbidity data.
• Synthesis of information on the course, impairment, and healthcare utilization associated with panic disorder.

Main Results:

• Panic disorder has a chronic course with limited remission, leading to significant social and functional impairment.
• Individuals with panic disorder experience increased risks of relationship problems, financial dependence, and poor health.
• Panic disorder is associated with high utilization of both general and mental healthcare services.

Conclusions:

• Despite advances, significant questions remain regarding the etiology, natural history, and prevention of panic disorder.
• Current epidemiological data lack detail on the role of risk factors in the developmental stages of panic disorder.
• Further research is needed to fully understand and manage panic disorder effectively.
