Multiple chemical sensitivity

Multiple chemical sensitivity (MCS) is an unrecognized and controversial diagnosis characterized by chronic symptoms attributed to exposure to low levels of commonly used chemicals.[1][2] Symptoms are typically vague and non-specific. They may include fatigue, headaches, nausea, and dizziness.

Although these symptoms can be debilitating, the cause is unknown. MCS is not recognized as an organic, chemical-caused illness by the World Health Organization, American Medical Association, or any of several other professional medical organizations.[3][obsolete source] Recent imaging studies have shown that it is likely a neurological condition.[4]

MCS is a chronic disease that requires ongoing management. In the long term, about half of people with MCS get better and about half continue to be affected, sometimes severely.[5]

Note 1: This syndrome is characterized by the patient's belief that his or her symptoms are caused by very low-level exposure to environmental chemicals. The term "chemical" is used to refer broadly to many natural and man-made substances, some of which have several chemical constituents. Note 2: ...
