The complex of symptoms associated with chronic fatigue syndrome (CFS) and Lyme disease can be very similar. The strong similiarities can result in delayed diagnosis or even misdiagnosis. Symptoms which are common to both conditions include:

• Sleep disturbances
• Fibromyalgia
• Dysautonomias (malfunction of the autonomic nervous system)
• Extreme fatigue often associated with cognitive impairment

In the Journal of Chronic Fatigue Syndrome (DOI: 10.1300/J092v13n04_06), the case study of a 33 year old man was presented. For two years, the man was treated for CFS with limited success. Once doctors reconsidered the diagnosis of Lyme disease for the patient, realizing he had a history of prolonged exposure to tick-infested mountains, they were able to confirm Lyme disease and alter disease management. With the accurate diagnosis, the patient improved and achieved better function. Researchers concluded it is very important to be aware that chronic Lyme disease can present as CFS.
