Epidemiology: Insomnia

Introduction

In this analysis, Datamonitor estimates that there were a total of 53 million cases of insomnia in 2010 in the seven major markets with nearly a half of these cases present in the US. Prevalence rates for insomnia are expected to remain constant; therefore, any changes in prevalence will depend on population dynamics in the seven major healthcare markets

Features and benefits

* Gain insight to market potential, including a robust 10-year epidemiology forecast of prevalent insomnia cases.
* Understand the key epidemiologic risk factors associated with insomnia.

Highlights

Datamonitor expects an increase in prevalent insomnia cases in the next decade in the seven major markets as a result of an ageing population.
Unsatisfactory sleep can cause severe distress and cause social, interpersonal, and occupational impairment.

Your key questions answered

* What are the most robust epidemiologic studies for insomnia prevalence data?
* How will the patient population change over the next decade in the US, Japan, and five major EU markets (France, Germany, Italy, Spain, and the UK)?
* How do changes in population structure and risk factors affect the trend in prevalent insomnia cases?
