A severe blow to the head may bring an unexpected consequence: disruptions in sleeping patterns that last for more than a year after the injury, a new study from Switzerland finds.
In the study, researchers looked at 31 people who had suffered a traumatic brain injury (TBI). Scientists investigated how long the individuals slept, whether their sleep was fragmented and how rested they felt while they were awake. A TBI is a brain injury resulting from traumatic impact, in which the brain’s day-to-day function is disrupted, according to the Centers for Disease Control and Prevention (CDC). The researchers also looked at a control group of 42 uninjured people.
