Abstract:
Study investigated the night-to-night consistency of diagnosing and classifying obstructive sleep apnea (OSA) using nocturnal polysomnography (NPSG) in individuals with traumatic brain injury (TBI). NPSG is considered the gold standard for detecting the presence of sleep apnea. However, there is a limitation with its use known as the “first-night effect” (aberrant polysomnography findings on the first night in a sleep lab). Forty-seven adults with self-reported mild-to-severe TBI underwent two nights of in-laboratory NPSG to examine variability between the first and second night with regards to OSA diagnosis and severity as well as sleep architecture. Results showed that OSA detection and severity were consistent from night-to-night in 89 percent of participants with TBI. Participants demonstrated longer rapid eye movement latency on the first night compared to the second night of the sleep study. These findings indicate that two nights of in-laboratory NPSG are generally consistent in reliably diagnosing OSA in individuals with TBI and that first-night effects are minimal. One night of NPSG has diagnostic utility in the evaluation of sleep disorders in individuals with TBI.
