Brain Imaging Study Sheds Light on Fibromyalgia
Addiction Drug May Help Ease Fibromyalgia
Fibromyalgia is a disorder that causes pain in your muscles and joints. It may also cause headaches, muscle stiffness, body aches and can disrupt your sleep. Stress or lack of sleep can make the symptoms of fibromyalgia worse. More women than men have fibromyalgia, and the disorder is common--it is seen in up to 5% of the population. However, it isn't life-threatening and it doesn't cause permanent damage.
The treatment for fibromyalgia is usually a combination of medicine to ease pain and self-care. One of the best things you can do if you have fibromyalgia is exercise. Begin with stretching exercises and gentle, low-impact activity, such as walking, swimming or bicycling. Start your exercise program slowly because at the beginning, exercise may make your pain worse. Some muscle soreness is normal when you're starting to exercise, but sharp pain may be a sign that you have overworked or injured your muscles.
As you progress with exercise, it will become more comfortable for you. For exercise to help, you must do it regularly. The goal is to get started and keep going, to gain relief from pain and to improve sleep. Below are some exercises you might want to try:
Walking: Start slowly by walking 5 minutes the first day. The next day, add a minute to this total. Keep adding 1 or 2 minutes a day until you are walking 60 minutes a day. When you reach this point, walk for at least 1 hour, 3 or 4 times a week. If you find yourself struggling as you're working your way up to walking for 60 minutes, go back to a length of time that was comfortable for you, and continue walking for this period of time for several days. Then continue to increase the minutes again until you reach the goal of 60 minutes. Try as many times as you need to reach the goal of walking for 60 minutes.
Walking/jogging: After you feel comfortable walking 3 or 4 times a week, you can alternate walking with slow jogging. Walk 2 blocks, then jog 1 block, walk 2 blocks, jog 1 block, and so on. Do this as often as it feels comfortable. Extend your exercise for longer periods if you feel comfortable.
Bicycling: Stationary bicycles (exercise bikes) offer the benefit of exercising indoors. Keep track of your mileage, or set a goal of bicycling for 60 minutes.
Swimming: Swimming is a great source of exercise that is very gentle on your joints. Try treading water for 1 to 2 minutes at a time, or swimming several laps. Try to work up to swimming laps for 30 total minutes.
The type of exercise you choose is up to you. It's important that you start exercising and keep doing it. Exercise relieves much of the pain fibromyalgia causes. Some people even find that exercise makes all their pain go away. You will also feel better if you have some control over your own care and well-being.
Scans Reveal Brain Abnormalities in Fibromyalgia Patients
Finding offers more evidence that the condition is 'real', researchers say
Researchers have detected abnormalities in the brains of people with fibromyalgia, a complex, chronic condition characterized by muscle pain and fatigue.
"We showed in our study that the functional abnormalities observed were mainly related to disability," and not to anxiety and depression status, said Dr. Eric Guedj, the study's lead author and a researcher at Centre Hospitalier-Universitaire de la Timone in France.
While some researchers have suggested that the pain reported by fibromyalgia patients was the result of depression, the new study suggests otherwise. The abnormalities found on brain scans done by the study authors were independent of the women's anxiety and depression levels, Guedj said.
The French researchers evaluated 20 women diagnosed with fibromyalgia and 10 healthy women without the condition who served as a control group. They asked all the women to respond to questionnaires to determine levels of pain, disability, anxiety and depression.
Then, the researchers performed brain imaging called single photon emission computed tomography, or SPECT.
The imaging showed that women with the syndrome had "brain perfusion" -- or blood flow abnormalities -- compared to the healthy women. The researchers then found that these abnormalities were directly correlated with the severity of disease symptoms.
An increase in blood flow was found in the brain region known to discriminate pain intensity, the researchers found.
The findings were published in the November issue of The Journal of Nuclear Medicine.
An estimated 10 million Americans are thought to have fibromyalgia, the majority of them women, according to the National Fibromyalgia Association. They report a history of widespread pain in all four quadrants of the body for at least three months, and pain in at least 11 of 18 "tender points."
Besides pain, fibromyalgia symptoms include fatigue; problems with cognitive functioning, memory and concentration; difficulty sleeping; and stiffness.
The cause of fibromyalgia remains a mystery, according to the association, but it may occur following physical trauma such as an injury, experts say. Treatments focus on relieving symptoms and helping patients function.
In previous research, Guedj and his team had found functional abnormalities in areas of the brain of fibromyalgia patients. The latest study goes a step further, demonstrating that the brain abnormalities are correlated with disease severity, he said.
Dr. Patrick Wood, senior medical adviser for the National Fibromyalgia Association, said the new study provides "further evidence of an objective difference between patients with fibromyalgia and those who don't have the disorder." Wood reviewed the study results but was not involved with the research.
Other studies have found a correlation between brain abnormalities and fibromyalgia symptoms, Wood said, adding that the new study adds more evidence and information on how the abnormalities affect patients.
