Healio: Many adults with a traumatic brain injury had a persistent form of insomnia for up to 12 months, according to a prospective cohort study published in JAMA Network Open.

“Insomnia can develop during the acute (0 to 7 days), subacute (8 to 90 days), or chronic (>90 days) phase after TBI,” Emerson W. Wickwire, PhD, of the Sleep Disorders Center and division of pulmonary and critical care medicine in the department of medicine at the University of Maryland School of Medicine in Baltimore, and colleagues wrote. “Not only can TBI disturb sleep, but there is evidence that poor sleep is associated with neurodegeneration, independently contributing to morbidity and long-term sequelae of TBI.”

Wickwire and colleagues set out to identify any various tracks of insomnia in the 12 months following incidence of TBI.

Participants were screened through the Federal Interagency Traumatic Brain Injury Repository (FITBIR), a data cache for federally funded research projects in the U.S., which yielded 2,022 suitable candidates, including those aged 17 years and older already taking part in the Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) study.
