"connie" 29. februar 2004 Hi Folks, The NEW online version of the long awaited "WHO Guide to Mental and Neurological Health in Primary Care" can be read at: http://www.whoguidemhpcuk.org/index.asp Please note the following: "The terms 'Post-viral fatigue syndrome' and '(benign) myalgic encephalomyelitis' (classified under G93.3 'neurological disorders') have been used where there is excessive fatigue following a specific trigger such as a viral disease and/or where the symptoms do not fulfil the criteria for F48.0. 'Fatigue syndrome', both chronic and not, with or without an established physical precursor, has been classified under 'neurasthenia', F48.0. In practice, there is extensive overlap in symptoms (up to 96%)." This statement can be found at: http://www.whoguidemhpcuk.org/page_view.asp?c=16&did=2099&fc=005027 The CFS or CFS/ME section can be found at: http://www.whoguidemhpcuk.org/content_show.asp?c=16&fid=895&fc=005027 Chronic fatigue syndrome (CFS or CFS/ME) G93.3. CFS is commonly referred to as (benign) myalgic encephalomyelitis (encephalopathy) or ME. A range or spectrum of disorders exists, characterized by abnormal levels of and unusual types of fatigue, along with other features and symptoms. Whether these represent distinct entities or variations on a common theme is uncertain. Aetiology and pathogenesis are not always known. Terminology is therefore problematic. "Incidence and prevalence of some neurological conditions" can be found at: http://www.whoguidemhpcuk.org/page_view.asp?c=16&did=2610&fc=001002 Take care all. Connie
