Functional connectivity abnormalities were observed in participants, including reduced engagement in task-related brain regions and apparent difficulties in regulating default mode brain areas that appeared to reverse following CBT-I treatment. CBT-I administration varied in treatment length and duration across the studies, as did neuroimaging assessment, which included task-based and resting-state functional magnetic resonance imaging (fMRI), and structural magnetic resonance imaging (MRI). Nine studies met current review selection criteria, of which six studies compared insomnia groups with good sleepers, waitlist, and/or control groups. This systematic literature review aimed to evaluate a growing body of exploratory studies that have examined CBT-I treatment effects using neuroimaging assessment. N2 - Cognitive behavioral therapy for insomnia (CBT-I) is the gold-standard non-pharmacological treatment for insomnia, a complex disorder that comprises psychological, behavioral, and physiological components. T1 - Neuroimaging Correlates of Cognitive Behavioral Therapy for Insomnia (CBT-I): A Systematic Literature Review Taken together, the neuroimaging results complement behavioral measures of treatment efficacy, indicating support for the effectiveness of CBT-I treatment in the recovery of brain function and structure.", Taken together, the neuroimaging results complement behavioral measures of treatment efficacy, indicating support for the effectiveness of CBT-I treatment in the recovery of brain function and structure.Ībstract = "Cognitive behavioral therapy for insomnia (CBT-I) is the gold-standard non-pharmacological treatment for insomnia, a complex disorder that comprises psychological, behavioral, and physiological components. This study contributes to the growing body of literature supporting Cognitive Behavioral Therapy for Insomnia as an evidenced based treatment option for veterans experiencing insomnia through a dissemination of the findings, strengths, limitations, and implications for future research.Cognitive behavioral therapy for insomnia (CBT-I) is the gold-standard non-pharmacological treatment for insomnia, a complex disorder that comprises psychological, behavioral, and physiological components. Studies included in this systematic review produced these findings: improvements in sleep quality, sleep efficiency, sleep onset latency, total sleep time, a reduction in depressive and insomnia symptoms, increased normalization of sleep, and a reduction in dysfunctional beliefs about sleep. This framework was utilized to explore Cognitive Behavioral Therapy as an effective means of treating veterans experiencing insomnia. The Behavioral Model of Insomnia was used as the conceptual framework for this review. Using the sociology research database SocINDEX nine studies examining the effectiveness of Cognitive Behavioral Therapy as a treatment option for insomnia and insomnia related symptoms met criteria for the review. In this systematic literature review, research regarding veterans experiencing insomnia and the utilization of Cognitive Behavioral Therapy for Insomnia as an effective treatment modality were synthesized.
