A study published in the medical journal PLoS ONE suggests that patients affected by fibromyalgia show changes in cerebral blood flow. These changes could be the cause of painful symptoms.
Researchers from the University of Valencia conducted a study on 30 women, including 15 affected by fibromyalgia to understand the impact of the disease on cerebral blood flow. The brains of subjects was observed through a technique of transcranial Doppler, a method of diagnosing ultrasonic observing the changes of blood flow by analyzing his brain speed in the major blood vessels.
Patients with fibromyalgia showed a disturbed cerebral blood flow, especially in the left hemisphere of the brain.
