A study published recently in the journal Frontiers in Human Neuroscience found that although traumatic brain injuries (TBI) can disrupt sleep, patients who can sleep after a TBI receive the same memory-consolidating benefits of sleep as their peers without brain injuries.
Disruptions in sleep and memory are common symptoms after a traumatic brain injury. Even patients who suffer a mild TBI may struggle to sleep well and to remember things. In most people, sleep helps the brain retain information it has learned during the day. Researchers wanted to know whether people with TBIs would also find it easier to remember things after they slept, even though the TBI did affect their sleep.
