Diagnosis is based on a history of illness that suggests chronic fatigue syndrome and by systematic exclusion of other possible causes of a person's symptoms. However, people of different races and ages have been diagnosed. Diagnosis in some groups might reflect cultural differences and differences in access to medical care. Studies are needed to determine risk factors for the disorder. Without knowing the cause, it is difficult to identify effective treatments.
Doctors can, however, prescribe medicines to relieve symptoms.
CDC is currently conducting studies to determine how common chronic fatigue syndrome is in the United States. Prevention steps can be devised once the cause of chronic fatigue sydrome is identified. If you have any questions about the disease described above, consult a health-care provider.
