Internal links are links from one MEpedia page to another. In contrast, links to websites outside MEpedia are called “external links”.
Typically, page names will be linked to once in the introductory section of an article (the lead paragraph), and then will be linked to again the first time the page name appears in the rest of an article. However, this is only a guideline, subject to editor discretion. For instance, if an important page name is mentioned three times in the body of a very long article, it may serve the reader to create an internal link each time.
When adding a reference to a page, consider using "author links" to link to any pages on the named authors of scientific papers (even if they are cited multiple times in the same article). For more information on this, please see MEpedia:Author links.
Linking to a page that doesn't exist yet
Sometimes you may want to link to a relevant page, even though no one has created that page yet. If it's relevant to ME, go ahead and link to it anyway. The link will show up as a red link but it will also be added to the list of wanted pages. Once the page is created, all red links to it throughout MEpedia will turn blue. See more about this at MEpedia:Wanted pages.
myalgic encephalomyelitis (ME) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.
