Chronic Pain and Mental Disorder

Pain is a kind of complex psychological process of biology.Pain perception and emotional activities are inseparable;pain is a kind of feeling,emotion and multidimensional nature of the cognitive experience that vary widely between people and even within an individual depending on the context and meaning of the pain and the psychological state of the person.Cognitive and emotional factors have a surprisingly important influence on pain perception.This article reviews the neural mechanisms underlying the modulation of pain by cognitive and emotional states-important components of mind-body therapies.It will also examine the accumulating evidence that chronic pain itself alters brain circuitry,including that involved in endogenous pain control,suggesting that controlling pain becomes increasingly difficult as pain becomes chronic.
