Sleep immediately after a concussion and 30 days later

What is it about?

Individuals who have sustained a concussion often report sleeping more than usual. Furthermore, individuals with a prior history of concussion often experience insomnia long after the concussion has resolved. However, objective quantification of these sleep patterns is lacking. In this article, we observed that, while individuals with an acute concussion get similar average amounts of sleep over five nights, the night-to-night variability in sleep duration is much higher for concussed individuals at the time of injury and one-month post-injury.

Why is it important?

Increased variability in night-to-night sleep duration is associated with numerous cardiovascular, endocrine, and mental health conditions. Individuals with a history of concussion may be predisposed to these if such increased variability persists beyond the first month.
