SleepSMART for Veterans With Insomnia and Mild Cognitive Impairment

Description

With increasing age, adults report greater frequency of insomnia symptoms, including difficulty falling and staying asleep, waking too early, and associated impairments in daytime functioning and quality of life. Veterans are particularly vulnerable to insomnia, with rates double and even triple those of civilian populations. When left untreated, chronic insomnia may contribute to increased risk for cognitive decline (e.g., Alzheimer’s disease) and can lead to poorer physical health, disruption in major social and occupational responsibilities, and decreased quality of life. CBT-I is the first-line treatment for insomnia, but factors like poor adherence and poor recall for CBT-I content can diminish its impact for certain populations. Specifically, the cognitive impairments experienced by individuals with Mild Cognitive Impairment (MCI) may limit the adherence and rate of progress in CBT-I. Therefore, it is critical to ensure that vulnerable populations, such as older Veterans with MCI, can fully benefit from sleep treatment. The study team developed SleepSMART (Sleep Symptom Management and Rehabilitation Therapy) to help cognitively impaired Veterans learn and adhere to the CBT-I regimen, thereby leading to faster and more complete sleep treatment benefits. Based on the results of a recent pilot investigation, SleepSMART demonstrated preliminary efficacy as a modified form of CBT-I treatment that is uniquely tailored to aging Veterans with MCI. This investigation will build on previous research by conducting a randomized controlled trial investigating the effectiveness of SleepSMART, compared to standard CBT-I, in 150 Veterans age 60+ with insomnia and MCI.
