Narrowing the CFS field with the fatigue scope

Because CFS embraces so many symptoms in addition to plain, old exhaustion, doctors and researchers are working on narrowing the fatigue scope — more clearly defining the intensity and duration of fatigue caused by CFS. By narrowing the fatigue scope, they can concentrate on defining the other characteristics of the illness and more easily determining whether a person has CFS or something else.
The best way for a doctor to narrow down the fatigue and make a correct diagnosis is to ask questions. She determines whether the patient’s fatigue is indeed as prolonged as he says and performs diagnostic tests to eliminate other illnesses that can cause fatigue to narrow it down.
