Multiple chemical sensitivity

Common card · No. 463316

Multiple chemical sensitivity (MCS) is an unrecognized and controversial diagnosis characterized by chronic symptoms attributed to exposure to low levels of commonly used chemicals. Symptoms are typically vague and non-specific. They may include fatigue, headaches, nausea, shortness of breath, cognitive difficulties and dizziness. Recent imaging studies have shown that it is likely a neurological condition. MCS is a chronic disease that requires ongoing management. In the long term, about half of people with MCS get better and about half continue to be affected, sometimes severely.
