Background: Identification and management of comorbidities in TBI has become an increasing focus for optimizing TBI outcomes. Recent meta-analyses highlight sleep disturbance and sleep disorders following TBI (Mathias & Alvaro, 2012). Improving the recognition and treatment of sleep disorders in TBI should be a central focus of rehabilitation. The Traumatic Brain Injury Model System (TBIMS) has created an infrastructure allowing multi-center investigations into sleep dysfunction in those who have had a moderate to severe TBI and received inpatient rehabilitation.
Objective: This paper will describe the 1) infrastructure used to advance sleep dysfunction/disorders research following TBI, 2) preliminary findings from these studies, and 3) repository of data which can be accessed for secondary analyses by investigators outside of the TBIMS infrastructure.
Methods: Two internal mechanisms allow investigators at TBIMS sites to collaborate on projects of shared interest: Research Modules and Special Interest Groups (SIG).
Results: To date, five studies have resulted from the TBIMS collaborative process focusing on insomnia, circadian disruption, and sleep apnea.
Conclusions: Future directions for the SIG include continued development of available knowledge and understanding of the multidimensional factors that contribute to TBI-related sleep disturbance, optimal assessment tools, effectiveness of available treatments, and treatment compliance in this population.
