Consensus criteria for the definition of multiple chemical sensitivity (MCS) were first identified in a 1989 multidisciplinary survey of 89 clinicians and researchers with extensive experience in, but widely differing views of, MCS. A decade later, their top 5 consensus criteria (i.e., defining MCS as [1] a chronic condition [2] with symptoms that recur reproducibly [3] in response to low levels of exposure [4] to multiple unrelated chemicals and [5] improve or resolve when incitants are… 
Chemical Sensitivity-The Frontier of Diagnosis and Treatment
TLDR
A scientific approach to the management of CS is proposed, by introducing the latest developments in diagnosis and treatment and provide insight into requirements for future study.
Multiple Chemical Sensitivity
TLDR
A general overview of the history, definition, demographics, prevalence, and etiologic challenges in defining and understanding MCS is provided.
Multiple Chemical Sensitivity: Discriminant Validity of Case Definitions
TLDR
Using the University of Toronto's Health Survey self-administered questionnaire to determine discriminant validity of multiple chemical sensitivity definitions, features from 2 of 7 case definitions achieved good discrimination and identified patients with an increased likelihood ofmultiple chemical sensitivity.
A Multiple Center Study of Multiple Chemical Sensitivity Syndrome
TLDR
The study data suggested that the domains operationalized by the questionnaire had reasonable psychometric characteristics, which support the fact that Multiple Chemical Sensitivity syndrome is often overlooked–even by those physicians who treat it most frequently–and that use of both sets of objective criteria for identifying the syndrome would greatly improve the sensitivity of physician diagnoses.
Review of the Available Scientific Evidence on Multiple ChemicalSensitivity Syndrome
TLDR
It is believed that the adoption of measures to sensitize the general population about MCS, could influence the reduction of exposures to trigger substances and improve understanding of this disease and people who suffer it.
Italian Expert Consensus on Clinical and Therapeutic Management of Multiple Chemical Sensitivity (MCS)
TLDR
The first Italian MCS consensus had the double aim: to improve MCS knowledge among healthcare workers and patients by standardizing the clinical and therapeutic management to MCS patients and to improve and shed light on MCS misconceptions not supported by evidence-based medicine (EBM).
Multiple chemical sensitivity
MCS goes under many names and overlaps with many other syndromes and conditions (see Table 50.1). The most frequently used terms recognize that chemicals and the environment are understood by the

Multiple chemical sensitivities syndrome: toward a working case definition.
TLDR
It is proposed that the major criteria accepted by the majority of survey respondents be used provisionally as the basis for categorizing cases in investigations of MCS syndrome.
The relationship between fibromyalgia and the multiple chemical sensitivity syndrome.
TLDR
Fibromyalgia patients with and without MCS did not differ in other symptomatology, and MCS may represent an additional symptom complex within the spectrum of FM, which is similar to those reported in other studies of MCS.
Prevalence and Overlap of Chronic Fatigue Syndrome and Fibromyalgia Syndrome Among 100 New Patients with Multiple Chemical Sensitivity Syndrome
TLDR
This study assesses the prevalence of pure MCS, M CS-CFS, MCS-FMS and the overlap of all three among 100 consecutive new patients evaluated for MCS in a private practice specializing in occupational and environmental medicine.
Prevalence of people reporting sensitivities to chemicals in a population-based survey.
TLDR
The homogeneity of responses across race-ethnicity, geography, education, and marital status is compatible with a physiologic response or with widespread societal apprehensions in regard to chemical exposure.
Prevalence and nature of allergy and chemical sensitivity in a general population.
TLDR
If the prevalence of sensitivity to chemical irritants is, in fact, equivalent to that of allergy, as was found in this study, then support for the scientific investigation of chemical sensitivity is justified.
VALIDATION OF A BRIEF SCREENING MEASURE OF ENVIRONMENTAL CHEMICAL SENSITIVITY: THE CHEMICAL ODOR INTOLERANCE INDEX
The development and validation of a brief self-report screening measure of environmental chemical sensitivity, the Chemical Odor Intolerance Index (CII), is described. Subjects included 1734 college
Comparison of patients with chronic fatigue syndrome, fibromyalgia, and multiple chemical sensitivities.
TLDR
Demographic and clinical factors and health locus of control do not clearly distinguish patients with CFS, FM, and MCS.
Neuropsychiatric and somatic characteristics of young adults with and without self-reported chemical odor intolerance and chemical sensitivity.
TLDR
Compared with their respective comparison groups, cacosmic and chemically sensitive groups had significantly higher incidences of illnesses associated with chemicals, alcohol intake, opiate drug use, and caffeine use, even after controlling for the psychological measures and histories of atopic allergy.
Chronic multisymptom illness affecting Air Force veterans of the Gulf War.
TLDR
Among currently active members of 4 Air Force populations, a chronic multisymptom condition was significantly associated with deployment to the GW and veterans who met the case definition had significantly diminished functioning and well-being.
Self-reported chemical sensitivity and wartime chemical exposures in Gulf War veterans with and without decreased global health ratings.
TLDR
Preliminary findings suggest the need for further study of chemical sensitivity, including tests for acquired increases in neural sensitizability to multiple low-level chemicals, in ill Persian Gulf War veterans.
