What is the history of Multiple Chemical Sensitivity?

When was Multiple Chemical Sensitivity discovered? What is the story of this discovery? Was it coincidence or not?


Multiple Chemical Sensitivity (MCS) is a controversial medical condition characterized by symptoms that are triggered by exposure to various chemicals in the environment. Individuals with MCS experience a range of symptoms, including headaches, fatigue, dizziness, nausea, and respiratory problems, when exposed to even low levels of chemicals found in everyday products such as cleaning agents, perfumes, and pesticides.



The history of MCS can be traced back to the early 20th century when reports of chemical sensitivities started to emerge. However, it wasn't until the 1950s and 1960s that the condition gained more attention. During this time, a condition known as "sick building syndrome" was identified, where individuals working in certain buildings experienced symptoms similar to MCS. This led to increased awareness of the potential health effects of indoor air pollution and chemical exposures.



In the 1980s, the term "Multiple Chemical Sensitivity" was coined by Dr. William J. Rea, an environmental physician. Dr. Rea observed that some patients exhibited symptoms in response to multiple chemicals and proposed that MCS was a distinct medical condition. This sparked further interest and research into the condition.



Throughout the 1990s, MCS gained recognition as a legitimate medical condition by some healthcare professionals, while others remained skeptical. The lack of consensus on diagnostic criteria and the absence of objective laboratory tests contributed to the controversy surrounding MCS. Some critics argued that MCS was a psychosomatic disorder or a result of other underlying conditions.



Despite the controversy, individuals with MCS sought recognition and support. They formed advocacy groups and raised awareness about the condition. In response, some governments and organizations implemented policies and guidelines to accommodate individuals with MCS, such as creating fragrance-free environments and reducing chemical exposures in public spaces.



Research into MCS has been ongoing, aiming to better understand the condition and its underlying mechanisms. Some studies have suggested that individuals with MCS may have heightened sensitivity to chemicals due to genetic factors, immune system dysfunction, or previous chemical exposures. However, the exact cause of MCS remains unknown, and more research is needed to establish a clear understanding of the condition.



Today, MCS continues to be a topic of debate within the medical community. While some healthcare professionals recognize it as a legitimate condition, others remain skeptical due to the lack of standardized diagnostic criteria and objective tests. The impact of MCS on individuals' lives can be significant, leading to lifestyle changes and avoidance of certain environments or products.



In conclusion, Multiple Chemical Sensitivity is a medical condition characterized by symptoms triggered by exposure to various chemicals. Its history can be traced back to the early 20th century, but it gained more attention in the 1950s and 1960s with the identification of sick building syndrome. The term "Multiple Chemical Sensitivity" was coined in the 1980s, leading to increased research and controversy surrounding the condition. Despite ongoing debate, individuals with MCS continue to seek recognition and support, while researchers strive to better understand the underlying mechanisms.

People have exhibited symptoms of MCS for quite some time. It is said that Edgar Allen Poe had suffered from MCS. Other notable instances are war veterans from the Gulf Wars and the 911 rescue workers. Because the medical community has had a hard time with defining and accepting the disease, patients have not been able to get proper treatment and had to seek help outside of the US medical environment.

There have been documented examples of chemical injuries and sensitivities for centuries. A classic one is Mad Hatters disease. The hatters used mercury to make beaver hats. When I was first diagnosed in 2004 and new nothing I found the website by Barbara Wilkie, Environmental Health Net of California. http://ehnca.org She has since past, 2011. She was a true champion. Anything about the history and the battle for recognition and accommodation can best be found there.

This goes back to when so many chemicals were added to our environment without proper testing.

I think it has come about starting from WW2. Lands desecrated with not only bodies but ordnance too. After the war many petroleum products appeared. It all stems from that. And advertising to sell us useless products.

MCS has been developing for decades, becoming progressively worse as the years pass. More and more chemicals have found their way into our homes and bodies through consumption, causing health issues and sensitivities. It is really quite mind boggling.

The condition now most commonly known as multiple chemical sensitivity (MCS) was brought to the attention of the U.S. medical establishment when the late Theron Randolph, a physician trained in allergy and immunology, reported that a number of his patients reacted adversely to chemicals in their environment (Randolph, 1952). He compared the condition to Selye's stress-oriented general adaptation syndrome (Kurt, 1995) and linked the adverse effects of this "petrochemical problem" to contact with chemicals found in commonly encountered substances such as cosmetics, auto fuels, exhaust fumes, and food additives. He also observed that many of his patients reacted to many industrial solvents found in small amounts in manufactured products such as construction materials, newspaper and other ink-related products, furniture, and carpet. Although Randolph and other physicians who shared his theories published articles in the medical literature during the 1950's and early 1960's, his views were not widely accepted among physicians, particularly those trained in allergy and immunology. In 1965, in response to this lack of acceptance within his specialty, he founded the Society for Human Ecology and invited physicians of all specialties (who were later often referred to as clinical ecologists) to take part. In 1985, the Society changed its name to the American Academy of Environmental Medicine (AAEM, 1992). Today, members are referred to as environmental physicians. However, the term clinical ecologist remains in use.

well in my IME WC case paperwork he mistakingly put Randolph Theron, but it is actually Theron Randolph, and Sherry Rogers a dr herself, was one of the first to start publishing about this.

First MCS patient was diagnosed in the late 1940's by clinical ecologist Dr. Theron Randolph, which led to the development of the field of clinical ecology.

Have no idea, interesting question will need to research

1/30/20 by Noeleen 2500

I don't know how to answer that

From memory: Long history as a "woman's illness." Not well studied because it involves multiple organ systems so it's difficult to isolate. Also not well studied because women's health issues are undervalued and more often dismissed as a mental health condition.

I'm not sure how far back it dates, but since the 60s and added chemicals in our world more people are falling Ill. Marketing has convinced people clean has a smell, so we are being bombarded by chemicals and fragrance non stop. This is why our numbers are increasing exponentially

Randolph in the 1950's discovered it first then the medical field picked up on it in the 1980's

Dr. Randolph first discovered MCS in the 1950s.

NO, I DON'T KNOW, I JUST KNOW THAT THERE IS A LOT OF INTRUSION OF ALTERNATIVE MEDICINES AND OTHER FALLACIES PSEUDOMÉDICAS.

Emilio : what Intrusion of alternative medicines? Allow me to disagree. I would rather say that Big Pharma is very well mounted to enrich themselves at the expense of the health. I don't know the history, but I know someone who has spent 58 years with SQM.
