Insomnia in the Population
Insomnia symptoms + daytime
consequences 9-15%
Insomnia symptoms-Overall prevalence 30-48%-Often or always: 16-21%-Moderate to extreme: 10-28%
Insomnia diagnosis
6%Direct economic costsof insomnia in the US are estimated ~ $14 billion Ohayon, Sleep Med Rev, 2002

Wall Disorders– Sleep-Related Hypoventilation / Hypoxemia due to Pulmonary Parenchymal or
Vascular Pathology• Other Sleep-Related Breathing Disorder

• Prevalence ~1 in 2000 (US)– Comparable to multiple sclerosis,
greater than cystic fibrosis• Men and women affected equally• Age at onset
– Can present at any age– Majority 15-30 years of age– 6% prior to 10 years of age
