[Multiple chemical sensitivity. Is the patient suffering as a result of environmental pollutants or psychological problems?]

Multiple chemical sensitivity (MCS) poses a medical challenge. Proposed etiologies are as numerous as they are contradictory, direct and indirect costs are high, and patient suffering considerable. In the absence of objective diagnostic criteria, estimation of its prevalence is difficult. Nevertheless, establishment of the diagnosis is frequently strikingly uncritical.

Therapeutical approaches should consider carefully the risk of avoidance and social withdrawal.     «
