Pain Disorders
Information and appreciation regarding the role of insufficient sleep in chronic pain is now emerging. This chapter reviews the sleep, daytime sleepiness, and fatigue of people with various chronic pain disorders. The bidirectional relation of sleep and pain is described in this chapter, and the modulating effects of mood and cognitive factors on the sleep-pain nexus are discussed. Central and peripheral mechanisms underlying the sleep–pain nexus are explored. Finally, pharmacological and behavioral treatments for sleep and pain are reviewed with a focus on the association of improved sleep leading to improved pain. It is concluded that further research is necessary to better understand the interrelation of sleep and pain, which may lead to better therapies for sleep and pain.
