Patients with persisting Lyme symptoms were previously found to have higher and more frequent anti-neural antibodies compared to people who were healthy or who had recovered from Lyme disease. Patients with chronic fatigue syndrome (CFS) and persisting Lyme disease often have similar symptoms. This study found that CFS patients do not have elevated anti-neural antibodies. Thus, the common symptoms of persisting Lyme and CFS are not likely due to anti-neural antibodies
