The reason is not known as yet but new research is in progress to elucidate this polysymptomatic disorder. Given the controversy surrounding the diagnosis, it is not surprising that treatment has become confused and emotional.
Many treatments continue to be tried and some partial successes have been found.
Treatments fall into a number of formats and these will be described. Such therapies are unsuccessful in part because the disease has a cause that few expected and vitamins will not alter. A few have had clinical trial data to validate them and none have curative intent. The best that could be hoped for, was and is, a slight improvement in function and the doctor has not always been helpful even with that. There is an increasing public demand for more effective therapies and proper support, not only from doctors but also now, highly skilled medical therapists such as dieticians, social workers etc.
