The pain from fibromyalgia is real

30.11.2006
University of Michigan doctors say widespread evidence verifies validity of condition, say patients should be taken seriously

Many people with fibromyalgia – a debilitating pain syndrome that affects 2 to 4 percent of the population – have faced the question of whether the condition is real.

Fibromyalgia often has been misdiagnosed as arthritis or even a psychological issue. Increasingly, though, the scientific knowledge about fibromyalgia is growing, and a new paper from the University of Michigan Health System says there are “overwhelming data” that the condition is real, is characterized by a lower pain threshold and is associated with genetic factors that can make some people more likely to develop fibromyalgia.

The review paper, in the December issue of the journal Current Pain and Headache Reports, cites recent studies involving pain, genetics, brain activity and more. The paper's authors hope these findings will lead to a better understanding and acceptance of fibromyalgia and related conditions.

“It is time for us to move past the rhetoric about whether these conditions are real, and take these patients seriously as we endeavor to learn more about the causes and most effective treatments for these disorders,” says Richard E. Harris, Ph.D., research investigator in the Division of Rheumatology at the U-M Medical School's Department of Internal Medicine and a researcher at the U-M Health System's Chronic Pain and Fatigue Research Center.

A growing amount of research related to the neurobiology of the condition supports the notion that the pain of fibromyalgia is real. Studies at U-M and elsewhere using two neuroimaging techniques – functional magnetic resonance imaging (fMRI) and single photon emission computed tomography (SPECT) – indicate there is a difference between patients with and without fibromyalgia.

“In people without pain, these structures encode pain sensations normally. In people with fibromyalgia, the neural activity increased,” says Daniel J. Clauw, M.D., director of the U-M Chronic Pain and Fatigue Research Center and professor of rheumatology at the U-M Medical School, and an author of the new paper. “These studies indicate that fibromyalgia patients have abnormalities within their central brain structures.”

In a 2003 paper in the journal Science, a U-M team reported that a small variation in the gene that encodes the enzyme called catechol-O-methyl transferase, or COMT, made a significant difference in the pain tolerance, and pain-related emotions and feelings, of healthy volunteers. Researchers also have found that individual mutations in the COMT gene are related to the future development of temporomandibular joint disorder, also known as TMD or TMJ, a condition related to fibromyalgia.

Together, these studies about COMT and numerous studies with animals suggest that pain sensitivity is determined at least in part by a person’s genetic makeup, Clauw says.

The authors note that there are some legitimate areas of debate regarding fibromyalgia, including disagreements about how precisely it should be defined and whether people with the condition deserve compensation. But none of those disagreements should detract from the acceptance of it as a condition causing real pain, they say.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
