Patients with PTSD experience less pain sensitivity — may be related to altered processing
January 02, 2007Patients with posttraumatic stress disorder show reduced pain sensitivity, a pattern that may be related to altered pain processing in the brain, according to a report in the January issue of the Archives of General Psychiatry, one of the JAMA/Archives journals.
Posttraumatic stress disorder (PTSD) is an anxiety disorder that may occur in individuals exposed to a traumatic event. It is characterized by chronic arousal, re-experience of the event, and avoidance of stimuli related to the event, according to background information in the article. To the authors' knowledge, no functional imaging study has explored whether patients with PTSD experience and process pain in a different way than control subjects.
Elbert Geuze, Ph.D., of Central Military Hospital and the Rudolph Magnus Institute of Neuroscience, Utrecht, the Netherlands, and colleagues conducted a study to examine neural correlates of pain processing in patients with PTSD. Twelve male Dutch veterans with PTSD and 12 male veterans without PTSD were recruited and matched for age, region of deployment and year of deployment. The experimental procedure consisted of psychophysical assessment and neuroimaging with functional magnetic resonance imaging (fMRI)-the use of magnetic resonance imaging to learn which regions of the brain are active in a specific function. During fMRI, the patients rated the pain they experienced from fixed and variable temperatures applied to their hands.
"Patients with PTSD rated temperatures in the fixed-temperature assessment as less painful compared with controls," the authors report.
"Before fMRI, patients with PTSD already showed a significant reduction in pain sensitivity," the authors write. "During imaging, patients with PTSD rated a fixed temperature as significantly less painful than control veterans." Patients with PTSD showed altered pain processing in brain areas associated with mood and cognitive pain processing.
"These data provide evidence for reduced pain sensitivity in PTSD. The witnessed neural activation pattern is proposed to be related to altered pain processing in patients with PTSD," the authors conclude.

Hebrew University researchers show how morphine can be given more effectively
Researchers at the Hebrew University of Jerusalem have found a way to maintain the pain-killing qualities of morphine over an extended period of time, thus providing a solution for the problem of having to administer increasing dosages of the drug in order to retain its effectiveness.
Study finds Zen meditation alleviates pain
Zen meditation - a centuries-old practice that can provide mental, physical and emotional balance - may reduce pain according to Université de Montréal researchers. A new study in the January edition of Psychosomatic Medicine reports that Zen meditators have lower pain sensitivity both in and out of a meditative state compared to non-meditators.
GSU study first to confirm long-term benefits of morphine treatment in infants
A recent study conducted by researchers at Georgia State University is the first of its kind to demonstrate that administration of preemptive morphine prior to a painful procedure in infancy blocks the long-term negative consequences of pain in adult rodents.
Too hot to handle! Scientists identify heat sensing regulator
Neuroscientists at Johns Hopkins are a step closer to understanding pain sensitivity - specifically why it's variable instead of constant - having identified a gene that regulates a heat-activated molecular sensor.
UCLA study finds brain response differences in the way women with IBS anticipate and react to pain
UCLA researchers found that women with IBS cannot effectively turn-off a pain modulation mechanism in the brain, which causes them to be more sensitive to abdominal pain, compared to women without IBS.
