Syndrome caractérisé par une fatigue persistante ou récurrente, des douleurs musculaires diffuses, des perturbations du sommeil, une diminution des capacités cognitives et ce, depuis au moins 6 mois. Ces symptômes ne sont ni provoqués par un effort, ni soulagés par le repos. Ils entraînent une diminution des activités professionnelles, scolaires, sociales ou personnelles. On retrouve parfois une altération mineure de l'immunité, du système neuroendocrinien et du système nerveux autonome. Il a pu être rapproché du syndrome de fibromyalgie. (Extr.

Definition (MEDLINEPLUS)
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.

Definition (MSH)
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.

Definition (NCI)
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.
