The label 'chronic fatigue syndrome' (CFS) has persisted for many years because of lack of knowledge of the etiological agents and of the disease process.
In view of more recent research and clinical experience that strongly point to widespread inflammation and multisystemic neuropathology, it is more appropriate and correct to use the term 'myalgic encephalomyelitis' (ME) because it indicates an underlying pathophysiology.
It is also consistent with the neurological classification of ME in the World Health Organization's International Classification of Diseases (ICD G93.3).
