Multiple Chemical Sensitivity

What is MCS/TILT?

Multiple chemical sensitivity (MCS), also known as toxic-induced loss of tolerance (TILT) or DELTA, is a syndrome often initiated by low-level chemical exposures. People afflicted by MCS suffer from a range of different symptoms, and can often link the onset of their symptoms to a specific event or type of exposure. Learn more.

Assessment Tools

Although there is currently no official diagnosis for MCS, several validated questionnaire instruments are available for assessing various aspects of environmental sensitivities or intolerance. Learn more.
