Chronic Fatigue Syndrome, or CFS, is a controversial disorder. Official medical classification of CFS as a disease has only existed since 1988, and since then the exact epidemiology and even definition of the disease has been contested and argued for decades. The debate currently hinges on whether or not CFS is a physiological disease, or a psychological or psychosocial disease. Some argue that CFS is strongly tied to depression and stress and a number of other psychological factors and in order to create improvement, psychological treatment is required. Conversely, many believe that CFS is a physiological disease with many possible causes, or even multiple causes, or potentially even a compounding of a number of conditions simultaneously.
