Abstract:

Study examined self-reported and objective sleep disturbance in individuals with traumatic brain injury (TBI) and explored possible relationships among sleep architecture and self-reported sleep quality, fatigue, and daytime sleepiness. Forty-four community-dwelling adults with TBI completed the Pittsburgh Sleep Quality Index (PSQI), the Multidimensional Assessment of Fatigue (MAF), and the Epworth Sleepiness Scale (ESS). They underwent two nights of in-laboratory nocturnal polysomnography (NPSG). Pearson product-moment correlation coefficients and hierarchical linear regression was used to analyze the data. Based on the PSQI cut-off score of ≥10, 22 participants were characterized as poor sleepers. Twenty-seven participants met criteria for clinically significant fatigue as measured by the Global Fatigue Index of the MAF. Fourteen participants met criteria for excessive daytime sleepiness as measured by the ESS. Poor sleep quality was associated with poor sleep efficiency, short duration of stage 2 sleep, and long duration of rapid eye movement sleep. There was little-to-no association between high levels of fatigue or daytime sleepiness with NPSG sleep parameters. Results show that a high proportion of the sample endorsed poor sleep quality, fatigue, and daytime sleepiness. Those who reported poorer sleep quality exhibited a shorter proportion of time spent in stage 2 sleep. These findings suggest that disruptions in stage 2 sleep might underlie the symptoms of sleep disturbance experienced following TBI.
