Multiple chemical sensitivity multiorgan dysesthesia, multiple symptom complex, and multiple confusion: problems in...

Area of Science:

• Environmental Medicine
• Clinical Toxicology
• Psychiatry

Background:

• Increasing patient reports of multiorgan symptoms linked to environmental chemical exposure.
• Alleged multiple chemical sensitivities (MCS) present with diverse symptoms like fatigue, confusion, and pain, often without objective physical signs.
• Lack of established diagnostic criteria for environmental agent effects necessitates careful clinical evaluation.

Purpose of the Study:

• To address the need for diagnostic criteria in evaluating patients with suspected environmental chemical exposure.
• To guide physicians in assessing patients presenting with symptoms attributed to multiple chemical sensitivities (MCS).
• To differentiate between organic disease and potential psychiatric comorbidities in MCS patients.

Main Methods:

• Comprehensive patient history and physical examination, including detailed chemical exposure assessment.
• Systematic evaluation for objective physical signs and physiological abnormalities.
• Consideration of psychiatric evaluation when objective findings are absent.

Main Results:

• Patients with alleged MCS frequently exhibit subjective symptoms without demonstrable tissue pathology or physiological abnormalities.
• Diagnosable psychiatric illnesses are often present in individuals with MCS.
• A definitive cause-effect relationship between multiple chemical exposure and reported symptoms remains unestablished.

Conclusions:

• Physicians should conduct thorough evaluations for patients reporting symptoms from environmental chemical exposure.
• When objective findings are absent, psychiatric assessment may be beneficial for patients with suspected MCS.
• Maintain an open mind regarding MCS, while acknowledging the lack of established scientific causality.
