It is defined by substantial impairment in preillness levels of activity and function, along with prominent symptoms of excessive fatigue, unrefreshing sleep, postexertional malaise (a general symptom provocation after a person's usual physical or cognitive exertion is exceeded), difficulty with cognitive tasks, and orthostatic intolerance (1).Many treatments are available to address individual ME/CFS symptoms, including interventions effective for postural tachycardia syndrome, syncope, fibromyalgia, chronic pain, and headaches.
