A study says months after a concussion or other traumatic brain injury, you may sleep more hours, but the sleep isn’t restorative, reports NPR.
“If you ask them, they say they are fine,” says Dr. Lukas Imbach, the study’s first author and a senior physician at the University Hospital Zurich in Zurich. When Imbach confronts patients with their test results, “they are surprised,” he says.
The results, published Thursday in the online edition of the journal Neurology,suggest there could be a quiet epidemic of sleep disorders among people with traumatic brain injuries. The injuries are diagnosed in more than 2 million people a year in the United States. Common causes include falls, motor vehicle incidents and assaults.
