At the present time multiple chemical sensitivities (MCS) is generally
acknowledged to be a poorly understood clinical syndrome which is exh
ibited by individuals exposed to low levels of exposure to environment
al agents that the general population tolerate quite well. A wide rang
e of individual symptoms (typically multiple and related to neurologic
, endocrine/metabolic, and immunological, often occurring simultaneous
ly) are displayed by MCS patients. Questions concerning whether or not
RIGS is a real clinical condition, a form of psychiatric illness or a
combination of both remain to be unambiguously clarified.
