Psychiatric treatments in multiple chemical sensitivity.

Despite the controversy and uncertainty surrounding the causes of the MCS syndrome, psychiatric treatments may provide some relief to MCS patients. These approaches may help patient and physician focus on the most important goals: relief of symptoms and improvement of function. Success requires that physician and patient establish a collaborative relationship and negotiate a treatment plan. Behavioral treatments are most effective at reducing disability and promoting a return to active life. When directed at appropriate target symptoms, psychopharmacologic treatments may reduce some of the most distressing symptoms of chemical sensitivity.
