Sleep And TBI Recovery

For patients with serious brain injuries, there’s a strong link between sleep patterns and recovery.  A study of 30 patients hospitalized for moderate to severe traumatic brain injuries found that sleep quality and brain function improved in tandem, researchers reported Wednesday in the journal Neurology.

Patients who still had low levels of consciousness and cognitive functioning would “sleep for a couple of minutes and then wake up for a couple of minutes,” both day and night, says Nadia Gosselin, the study’s senior author and an assistant professor in the psychology department at the University of Montreal.

But “when the brain recovered, the [normal] sleep-wake cycle reappeared,” Gosselin says.

The results raise the possibility that patients with brain injuries might recover more quickly if hospitals took steps to restore normal sleep patterns, Gosselin says. Drugs are one option, she says. Another is making sure patients are exposed to sunlight or its equivalent during the day and at night rest in a dark, quiet environment.

“I think bad sleep can have bad consequences for brain recovery,” she says.(npr.org)
