• onset
  • Broadly speaking however, the physical route of initialization of multiple chemical sensitivity is NOT well understood, although in the USA, in a study into the effects of the drug Neurontin, one part of the study specifically linked brain injury to the onset of multiple chemical sensitivity, concluding that the injury allowed easier sensitization to MCS excitants to occur than would otherwise have been the case. (multiplechemicalsensitivity.org)
  • Many patients who are suffering multiple chemical sensitivity report that following the onset of their problems, they became sensitive to "everything they breathe, eat & touch", which is often not far from the truth, ( refer generalization & spreading earlier). (multiplechemicalsensitivity.org)
  • injury
  • As already discussed, the mechanisms of multiple chemical sensitivity & environmental injury are only partly understood but usually start with one well-defined toxic event & this is often exposure to one toxic chemical, but, what comes as a surprise to many outsiders is that multiple chemical sensitivity can also be caused by a physical event or occurance, such as, for example, a car crash or a knock on the head. (multiplechemicalsensitivity.org)
  • Secondly looking at the physical route for the initialization of multiple chemical sensitivity environmental injury, this could be almost any injurious physical event. (multiplechemicalsensitivity.org)
