Use of neuropsychological testing in idiopathic environmental testing.
Individuals with idiopathic environmental intolerance (IEI) report fatigue, headaches, weakness, malaise, decreased attention/concentration, memory loss, disorientation, confusion, and psychological disturbances. These neurobehavioral symptoms may be a sign of possible alterations in the central nervous system (CNS). The evaluation of neurobehavioral functioning using standardized testing provides a surrogate measure of integrity of the CNS. However, the interpretation of neuropsychological test results must be made cautiously since this technique is extremely sensitive, but not specific. Abnormal test results could be due to a neurological disorder, a medical disorder, or a neuropsychiatric disorder. Therefore, when evaluating patients who present with symptoms of IEI, abnormal neurobehavioral results should not be attributed routinely to environmental chemical exposure until other causes are systematically ruled out.
