Multiple Chemical Sensitivity: The Controversy

Multiple Chemical Sensitivity (MCS) is still a controversial issue among medical doctors and clinical ecologists and has yet to be legitimized by the medical establishment and state medical-insurance institutions.


Controversy
Since MCS has not been clearly defined and many of its hypotheses are not testable, the American Medical Association and other medical professional organizations disagree with the Clinical Ecologists because they don't have the research, scientific or biological, to prove their beliefs.
Other factors that keep MCS controversial are the Clinical Ecologists' lack scientific documentation according to established scientific procedures and the use of experimental treatment and diagnostic procedures.

There are complex immunological tests and brain scans that appear to show abnormalities caused by chemical exposure, the medical profession does not consider this "reliable information." Also there are neuro-psychological tests given to MCS patients that measure brain function and can show decreased blood flow to some areas of the brain, according to Dr. Gordon Baker, a Burien allergist.

Scientifically oriented professionals suspect that the majority of MCS patients suffer from psychological disorders such as depression, anxiety reactions, and bodily reactions to stress. Many of them agree that, although some people are sensitive to one or a few specific chemicals, there is no general hypersensitivity to chemicals.

A wide army of names has been associated with MCS. Besides Multiple Chemical Sensitivity, it can be called Twentieth Century Disease, Environmental Illness, Environmental Sensitivity, Chemical Injury, Chemical Aids, Ecologic Illness, Total Immune Disorder Syndrome, or Total Allergy Syndrome.

Each of these names has specific implications regarding the underlying cause, mechanism, or manifestations of the disease. The difficulty in agreeing upon a definition or a name for this condition has been a major hindrance in achieving scientific respectability.


What is MCS?
Multiple Chemical Sensitivity is allergic reactions to chemicals that are often not antibody driven. A person with MCS can not detoxify and eliminate chemicals in his body because they are entering the body faster than it can eliminate them. The chemicals then store in the fatty tissues of the body - the heart, liver, and brain.
Allergy & Environmental Sensitivity Support & Research Association of Australia says MCS is like an allergy, in that people afflicted react to things that don't bother other people, but the biological mechanisms are different. [ Overview of our MCS model air purifier, air scrubber, air cleaner ]

Definition
Multiple Chemical Sensitivity is hard to define because it can encompass so many variables that are not consistent in each individual that suffers from the disorder. There is no commonly accepted definition of Multiple Chemical Sensitivity even though there are two definitions that are widely accepted by many doctors that have MCS training and understanding.
Dr. Mark Cullen, Yale School of Medicine, quoted by most Occupational and Environmental doctors, defines MCS as an acquired disorder characterized by recurrent symptoms, referable to Multiple organ systems, occurring in response to demonstrable exposure to many chemically unrelated compounds at doses far below those established in the general population to cause harmful effects.

Clinical Ecology, a clinical ecologists' journal, defines Ecologic Illness as a chronic multi-system disorder, usually polysymptomatic, caused by adverse reactions to environmental incitants, modified by individual susceptibility and specific adaptation. The incitants are present in air, water, food, drugs and our habitat.

To use language that is understandable to the average person, Multiple Chemical Sensitivity is a chronic condition that is characterized by multiple symptoms, in multiple organs, affecting multiple senses, and triggered by multiple chemicals.

Brief History
A wide range of new chemicals were synthesized after World War II and were put into the market place. Since then thousands of these petroleum based synthetic chemicals are added to products every year. They are in the household products we use, in the clothes we wear, in the food we eat, and in the air we breathe. Most of these chemicals have not been adequately tested for their potential toxicity and have become troublesome for many. 
Theron Randolph, M.D., a Chicago allergist, recognized in the early 1950's that people were getting sick from their environment. By the 1960's the government was aware that pollution was the cause of adverse health affects.

Because the government was wanting to conserve energy in the early 1970's, it encouraged the construction industry to become more energy efficient. This led to changing the ventilation requirements needed to bring fresh air into the new buildings being built. The combination of the ventilation changes in buildings and the increase in volatile chemicals being used in manufacturing materials led to what is now called sick building syndrome.

Medical doctors and scientists are starting to agree that different people react differently to modern man-made chemicals and that real progress has been made in defining the condition and understanding some of its origins. 

Many physicians are most at ease when one kind of germ causes one kind of disease, therefore, they are not comfortable treating MCS because it encompasses many unknowns, many causes, and many symptoms.

The next article will discuss who is afflicted, the causes, triggers, symptoms, and treatment of MCS.
