Despite abnormalities after concussion, sleep continues to aid memory and recall
Jun 05, 2015
After a concussion, a person can be left with disturbed sleep, memory deficits, and other cognitive problems for years, but a new study from the University of Massachusetts Amherst suggests that despite these abnormalities, sleep still helps them to overcome memory deficits, and the benefit is equivalent to that seen in individuals without a history of mild traumatic brain injury.
