Chronic fatigue syndrome (CFS) is a condition characterized by prolonged fatigue that does not disappear even after extended rest. The disease has many symptoms. These include confusion.. Experts from Columbia University tried to find out the cause of this symptom..

Researchers measured the levels of 51 markers of inflammation from a group of cytokines in cerebrospinal fluid in 32 people with an average of 7 years suffering from CFS, 40 patients with multiple sclerosis and 19 healthy people.. Scientists used the method of enzyme immunoassay. The levels of most cytokines, including interleukin-1, were lower in participants with chronic fatigue syndrome than in volunteers from the other two groups, Rosbalt reports..

One cytokine, eotaxin, was elevated in people with multiple sclerosis and in participants with CFS compared to controls. In a previous study, researchers found similar results when testing the blood of people with chronic fatigue syndrome..

So, changes occur not only in the blood, but also in the central nervous system.. Experts hope that their findings will help develop new methods for the diagnosis and treatment of CFS, writes MedDaily.
