OBJECTIVE: To determine the occurrence and nature of sleep-related breathing disorders in adults with traumatic brain injury (TBI). DESIGN: Prospective, observational, consecutive sample enrollment of subjects admitted for rehabilitation after TBI. SETTING: Inpatient rehabilitation and subacute rehabilitation units of a tertiary care university medical system. Subjects (n = 28) included adults with TBI and a Rancho Los Amigos Scale level of 3 or greater who were less than 3 months postinjury and admitted for comprehensive inpatient rehabilitation. Overnight sleep study using portable 6-channel monitoring system. MAIN OUTCOME MEASURE: Respiratory disturbance index (RDI), which is the number of apneic and hypopneic episodes per hour of sleep. RESULTS: Evidence of sleep apnea was found in 10 of 28 (36%) subjects as measured by a RDI level of 5 or greater and in 3 of 28 (11%) subjects as measured by a RDI level of 10 or greater. This rate of sleep apnea is significantly (p =.002) higher than would be predicted based on population norms. No correlation was found between the occurrence of significant sleep apnea and measures of TBI severity or other demographic variables. Sleep-related breathing disorders were primarily central though obstructive apneas were also noted. CONCLUSION: In this preliminary investigation, sleep-related breathing disorders as defined by a respiratory disturbance index of 5 or greater appears to be common in adult subjects with TBI.
