More sleep? An adaptive response to control pain after traumatic brain injury

In a recent issue of Sleep Medicine, Suzuki and coworkers [1] presented several considerations regarding posttraumatic hypersomnia in patients with a recent mild traumatic brain injury (mTBI). After one month, mTBI patients with moderate to severe pain (acute pain) presented more naps (>3 naps/day) and longer sleep (>8h/night) than patients with mild pain. After one year post-injury, mTBI patients continue to sleep longer, despite the presence of chronic pain.
