Why Is Panic Disorder Less Frequent in Late life?

Area of Science:

• Gerontology
• Psychiatry
• Epidemiology

Background:

• Panic disorder onset typically occurs before age 40.
• Prevalence of existing panic disorder cases decreases in later life.

Purpose of the Study:

• To review epidemiological findings on panic disorder in older adults.
• To explore hypotheses explaining the reduced frequency of panic disorder in old age.

Main Methods:

• Review of epidemiological studies on panic disorder prevalence across age groups.
• Exploration of potential contributing factors to decreased incidence in older populations.

Main Results:

• No evidence suggests methodological bias underestimating panic disorder in older adults.
• Disorder-associated mortality and age-related neurochemical changes are potential contributors.
• A cohort effect is a possible, though unproven, factor.

Conclusions:

• Panic disorder incidence and prevalence decrease significantly in older age.
• Mortality and neurobiological changes are likely drivers of this decline.
• Further research is needed to investigate cohort effects.
