Clinical Information
  • A condition lasting for more than 6 months in which a person feels tired most of the time and may have trouble concentrating and carrying out daily activities. Other symptoms include sore throat, fever, muscle weakness, headache, and joint pain.
  • A syndrome characterized by persistent or recurrent fatigue, diffuse musculoskeletal pain, sleep disturbances, and subjective cognitive impairment of 6 months duration or longer. Symptoms are not caused by ongoing exertion; are not relieved by rest; and result in a substantial reduction of previous levels of occupational, educational, social, or personal activities. Minor alterations of immune, neuroendocrine, and autonomic function may be associated with this syndrome. There is also considerable overlap between this condition and fibromyalgia. (from semin neurol 1998;18(2):237-42; ann intern med 1994 dec 15;121(12): 953-9)
  • A syndrome of unknown etiology. Chronic fatigue syndrome (cfs) is a clinical diagnosis characterized by an unexplained persistent or relapsing chronic fatigue that is of at least six months' duration, is not the result of ongoing exertion, is not substantially alleviated by rest, and results in substantial reduction of previous levels of occupational, educational, social, or personal activities. Common concurrent symptoms of at least six months duration include impairment of memory or concentration, diffuse pain, sore throat, tender lymph nodes, headaches of a new type, pattern, or severity, and nonrestorative sleep. The etiology of cfs may be viral or immunologic. Neurasthenia and fibromyalgia may represent related disorders. Also known as myalgic encephalomyelitis.
  • Chronic fatigue syndrome (cfs) is a disorder that causes extreme fatigue. This fatigue is not the kind of tired feeling that goes away after you rest. Instead, it lasts a long time and limits your ability to do ordinary daily activities. Symptoms of cfs include fatigue for 6 months or more and experiencing other problems such as muscle pain, memory problems, headaches, pain in multiple joints, sleep problems, sore throat and tender lymph nodes. Since other illnesses can cause similar symptoms, cfs is hard to diagnose.no one knows what causes cfs. It is most common in women in their 40s and 50s, but anyone can have it. It can last for years. There is no cure for cfs, so the goal of treatment is to improve symptoms. Medicines may treat pain, sleep disorders and other problems. Centers for Disease Control and Prevention.
  • Distinctive syndrome characterized by chronic fatigue, mild fever, lymphadenopathy, headache, myalgia, arthralgia, depression, and memory loss; candidate etiologic agents include epstein-barr and other herpesviruses.
  • Syndrome thought to be caused by a viral organism resulting in chronic fatigue, fever, pain, sore throat, and, in some cases, depression.
