Sleep-wake disturbances affect approximately 50% of children with acquired brain injury, and many children with preadmission chronic conditions have an increased risk for sleep-wake disturbances, a study in Pediatric Neurology suggests.

A total of 78 children (median age, 9.9 years) with acquired brain injury who had been released from critical care hospitalization within 3 months were enrolled in the prospective cohort study. Children were diagnosed with traumatic brain injury (n=40), stroke (n=11), infectious or inflammatory disease (n=10), hypoxic-ischemic injury (n=9), or other (n=8). The “other” diagnosis category included carbon monoxide, hemolytic uremic syndrome, severe sepsis, hippocampal necrosis after polypharmacy ingestion, and refractory status epilepticus. Sleep-wake disturbances were measured using standardized T scores from the Sleep Disturbances Scale for Children parent-reported, 26-item validated questionnaire.

Approximately 56% (n=44) of children had sleep-wake disturbances, with 46% (n=36) of these children having severe disturbances. In each diagnosis subgroup, the prevalence of sleep-wake disturbances was ≥33%. Approximately 47% of children with acquired brain injury had disturbance in the initiation and maintenance of sleep, which represented the most common phenotype in the sample. In addition, 68% of children had multiple concurrent sleep-wake disturbance phenotypes.

Chronic conditions prior to admission were observed in one-third of patients. The presence of preadmission chronic conditions was associated with sleep-wake disturbances in patients with traumatic brain injury (52% with disturbances vs 5% without disturbances; P =.001). Overall, the presence of preadmission chronic conditions was associated with an increased risk for sleep-wake disturbances (43% vs 21%; P =.04).

Limitations of the study include the small and unique patient population as well as the short follow-up and lack of preinjury sleep measures.

The researchers concluded that “sleep-wake disorders offer a potentially modifiable target to improve recovery after acquired brain injury.” They emphasized that these findings “underscore the importance of systematically evaluating sleep in these children.”
