Checking out my mail listings, I came across this one from 2009. I may have made use of it before and sent it on to others. Also it came from a contact.
The article is a summary of a complex research paper. The basic premise is that MCS is a brain (neurological) issue that is chemical in effect. Chemicals may impact on the brain in various ways.
They may enter the bloodstream by one means or another. They may come through the skin, despite the protestations of cosmetic and personal product makers. They may come via the lungs, in that humans breath.
Breathing in humans is something else heavily discounted by makers except for those of fragrances.
They need breathing humans to sell their stuff. But the makers insist that the sense of smell in breathing cannot impact adversely on the brain or if it does only in a way that conveys either pleasure or the release of the urge to mate.
Or something.

Multiple Chemical Sensitivity (MCS) is a chronic acquired disorder of unknown pathogenesis.
The aim of this study was to ascertain whether MCS patients present brain single photon emission computed tomography (SPECT) and psychometric scale changes after a chemical challenge.This procedure was performed with chemical products at non-toxic concentrations in 8 patients diagnosed with MCS and in their healthy controls.• In comparison to controls, cases presented basal brain SPECT hypoperfusion [decreased blood flow] in small cortical areas of the right parietal and both temporal and fronto-orbital lobes.• After chemical challenge, cases showed hypoperfusion in the olfactory, right and left hippocampus, right parahippocampus, right amygdala, right thalamus, right and left Rolandic and right temporal cortex regions.• By contrast, controls showed hyperperfusion in the cingulus, right parahippocampus, left thalamus and some cortex regions.• The clustered deactivation pattern in cases was stronger than in controls (p=0.012) and the clustered activation pattern in controls was higher than in cases (p=0.012).• In comparison to controls, cases presented poorer quality of life and neurocognitive function at baseline, and neurocognitive worsening after chemical exposure.Chemical exposure caused neurocognitive impairment, and SPECT brain dysfunction particularly in odor-processing areas, thereby suggesting a neurogenic [nervous system] origin of MCS.Source: Journal of the Neurological Sciences, Oct 2, 2009.

The increased power of many products in the last few years and with more to come must mean many more people will be affected. Any who are already affected will have more problems.
