Abstract

Human exposure assessment and the results of implementing 'precautionary avoidance' suggested a relationship between a hairdresser's neuropsychiatric symptoms and occupational exposure to potentially hazardous chemicals. A variety of investigations in response to patient complaints of depression, emotional instability and various physical symptoms revealed no objective abnormality; the CH2OPD2 mnemonic (community, home, hobbies, occupation, personal habits, diet and drugs) recommended by the Ontario College of Family Physicians was used as a first-line screening tool to assess potential environmental exposure to toxins. After occupational leave of absence, the patient reported cessation of symptoms. Environmental causes for familiar medical problems are frequently undiagnosed; it is recommended that, where appropriate, a screening tool for evaluation of environmental exposure to toxics be incorporated into primary care assessment and management of patients.

Abstract

Thoughts and moods are the result of biological processes; disordered thoughts and moods may be the result of disordered biological processes. As brain dysfunction can manifest with emotional symptoms or behavioral signs, the etiology of some mental health afflictions and some abnormal conduct is pathophysiological rather than pathopsychological. Various studies confirm that some chemical toxicants which modify brain physiology have the potential to affect mood, cognitive function, and to provoke socially undesirable outcomes. With pervasive concern about myriad chemical agents in the environment and resultant toxicant bioaccumulation, human exposure assessment has become a clinically relevant area of medical investigation. Adverse exposure and toxicant body burden should routinely be explored as an etiological determinant in assorted health afflictions including disordered thinking, moods, and behavior. The impact of toxicant bioaccumulation in a patient with neuropsychiatric symptoms is presented for consideration as an example of the potential benefit of recognizing and implementing exposure assessment.
