The direct costs of untreated comorbid insomnia in a managed care population with major depressive disorder

Abstract

Objectives:

Previous research has shown that untreated insomnia has significant direct and indirect burden. Despite the high comorbidity of insomnia and Major Depressive Disorder (MDD), no studies have attempted to determine the economic costs among patients diagnosed with MDD and insomnia. The purpose of this study was to estimate the economic burden of comorbid untreated insomnia within an adult and elderly population with MDD.
