Book excerpt: ritten by a noted expert in occupational and environmental medicine and neurology, this volume offers clinicians much-needed guidance in diagnosing and treating neurologic disorders caused by chemical exposure. The book delineates the key symptoms, presents an approach to assessing exposed individuals, and provides clinically relevant information on the twenty major occupational and environmental neurotoxicants. Discussions of the neurotoxic agents follow a consistent, user-friendly format. Dr. Feldman briefly describes the physical nature and chemical structure of each substance and its sources of exposure, recommended exposure limits, and metabolism. He then details the symptoms and physical findings associated with the substance, the most useful confirmatory diagnostic tests, and the most appropriate therapeutic and preventive measures. Finally, he presents case histories and discusses the acute and long-term risks of various exposure scenarios
