Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Many Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn era Veterans have suffered a mild traumatic brain injury (mTBI), and now cope with multiple post-injury symptoms, including sleep disturbances (especially insomnia). Chronic insomnia in mTBI patients has the potential to exacerbate other symptoms, delay recovery, and negatively affect many of the cognitive, psychological, and neuromuscular sequelae of mTBI, thereby decreasing quality of life. Although Cognitive-Behavioral Therapy for Insomnia (CBT-I) has been shown to be an effective evidence-based treatment for insomnia, there are no published randomized controlled trials evaluating the potential strengths and/or limitations of CBT-I in post-mTBI patients. Therefore, assessing CBT-I in the context of mTBI holds promise to provide substantial benefits in terms of improved rehabilitation outcomes in Veterans who have suffered mTBI.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This VA Rehabilitation Research and Development Career Development Award (CDA-2) proposal is designed to significantly advance the application of Behavioral Sleep Medicine practices in the treatment of Veterans seen in the VA Healthcare System, especially those recovering from traumatic brain injury (TBI). TBI has been deemed the "signature wound" of the Iraq and Afghanistan Wars, occurring in about 19.5% of Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) service members. For many Veterans, mild traumatic brain injury (mTBI) can be associated with persistent post-concussive symptoms, especially sleep disturbances. Sleep disturbances are among the most frequent complaints following mTBI, with studies suggesting that over 93% of Veterans who experienced brain injuries develop chronic sleep problems. Of the sleep disturbances diagnosed in this patient population the most common is insomnia, observed in over 50% of patients. Chronic and untreated insomnia is known to be associated with and/or increase risk for psychiatric problems, suicidal ideation, and unhealthy lifestyles (e.g., alcohol/drug abuse), lead to poorer physical health, disruption in major social and occupational responsibilities, and decreased quality of life, and may generally contribute to the persistence of post-concussive symptoms beyond the expected period of recovery. As such, treatment of sleep disturbance represents an essential component of Veteran care, one which may be particularly beneficial for Veterans with history of mTBI who commonly present to the clinic with complex multi-symptom concerns.

To address this important clinical issue, the proposed randomized clinical trial (RCT) will attempt to assess the efficacy of Cognitive-Behavioral Therapy for Insomnia (CBT-I) versus a Sleep Education control in Veterans with insomnia and a history of mTBI. CBT-I is recommended by the American Academy of Sleep Medicine for treatment of chronic insomnia and has also been adopted by the VA within an Evidence Based Practice roll-out program. Despite the acceptance of CBT-I as a first line treatment for sleep disturbance, there are no published RCTs evaluating CBT-I in mTBI patient populations. Therefore, this proposed investigation will address this gap in the literature by assessing the efficacy of CBT-I in Veterans with history of head injury.
