What is ME/CFS?

M.E. (Myalgic Encephalomyelitis) usually starts after a viral illness and is recognised as a neurological condition by the World Health Organisation (W.H.O). However, perhaps because it is a largely invisible illness with routine tests usually being normal (although research has found many subtle abnormalities), sufferers often face many difficulties getting appropriate support and treatment. It is often now diagnosed under the name Chronic Fatigue Syndrome (CFS).

Documents about ME/CFS

Some documents that might be useful for individuals with the illness, their family members and professionals, are as follows:

Front cover of the Canadian Consesus Document

This booklet was created by an international panel of experts under the auspices of Health Canada. We posted a copy, along with some other information, to all Irish GPs (over 2500) and 110 consultants in 2006. In 2008/2009, we again wrote to all Irish GPs, sending them a bundle of information including three copies of the ME/CFS diagnostic ticksheet from these guidelines.


Cover of primer booklet

This booklet was prepared by an international panel of experts who between them had diagnosed and/or treated more than 50,000 patients who have M.E. This covers both diagnosis and treatment. We have sent copies (along with other information) to nearly 1100 Irish GPs and hope to send copies to others when funds allow.

Front cover of booklet

Produced by the International Association for Chronic Fatigue Syndrome/ Myalgic Encephalomyelitis (IACFS/ME), "the largest international group of clinicians, researchers, and other professionals dedicated to the care and research of patients with ME/CFS".


Front cover of booklet

This was published in 2015. It was prepared by the august Institute of Medicine in the US (part of the National Academy of Science). They had been given $1 million by various US health agencies to develop evidence-based clinical (as opposed to research) diagnostic criteria for ME/CFS.

A short clinicians’ guide was published to facilitate its use.
