This guide has been developed by the Department of Family Medicine and Community Health – Wisconsin family medicine. It is an overview of what has been found useful for patients reporting MCS, Much of it is acnedotal and based on Surveys of patients with MCS. Unfortunately there is a big gap in research when it comes to EI conditions like Multiple Chemical Sensitivity. Some can be found at MCS Research James Madison University. Evidence suggests that MCS is a body and mind condition. Many people who report Multiple Chemical Sensitivity, are thought to be experiencing a Mast Cell Activation Disorder (MCAD) or Biotoxicity – Chronic Inflammatory Response Syndrome (CIRS). These are treated in similar ways to what is outlined in this handout for people with MCS.
